React Native Paper Dark Theme - javascript

How do I set the theme to dark theme in React Native Paper? In all my screens, all the <View>'s still have white backgrounds.
const theme = {
...DarkTheme,
colors: {
...DarkTheme.colors,
primary: '#2d3436',
accent: '#1C1C1C',
background : '#636e72'
}
};
render() {
return(
<PaperProvider theme={theme}>
<App />
</PaperProvider>
);
}

Applying a theme and provider level wont change all the views.
You will have to use the 'withTheme' when exporting which would provide the theme prop which you can use to access the colors.
import { withTheme } from 'react-native-paper';
const Test = ({ theme,children }) => {
const { colors } = theme;
return (
<View style={{ backgroundColor: colors.background }}>
{children}
</View>
);
};
export default withTheme(Test);
If you want to use the same theme for all Views, create a custom wrapper component which sets the color like above

using theme.spacing inside theme definition

I have the following theme setup:
export const themeDefault = createTheme({
themeName: 'Default (Mortgage Hub)',
spacing: 4,
...typography,
palette,
components: {
MuiButton: {
styleOverrides: {
root: {
paddingLeft: theme.spacing(12),
paddingRight: theme.spacing(4),
border: '10px',
},
},
},
},
})
And I would like to use theme.spacing inside however, of course. Theme is not defined yet. I have tried to use makeStyles & useTheme however these are hooks. So of course they will not work.
Are you able to supply styleOverrides once the theme has been indicated?
The styleOverrides feature of the theme is extremely powerful and versatile. In the Overrides based on props portion of the documentation, you can find an example of specifying a callback within the styleOverrides which then gives you access to the component's props and state (via ownerState) and the theme.
Below is an example showing how the callback syntax gives you access to the theme as well as showing how you can leverage ownerState to do conditional styles based on the props passed to a component (e.g. based on whether or not startIcon was specified or which variant was used or any combination of interest).
import * as React from "react";
import Stack from "#mui/material/Stack";
import Button from "#mui/material/Button";
import { createTheme, ThemeProvider } from "#mui/material/styles";
import SaveIcon from "#mui/icons-material/Save";
const theme = createTheme({
themeName: "Default (Mortgage Hub)",
spacing: 4,
components: {
MuiButton: {
styleOverrides: {
root: ({ ownerState, theme }) => {
const conditionalStyles = {};
if (ownerState.startIcon !== undefined) {
conditionalStyles.paddingLeft = theme.spacing(6);
if (ownerState.variant === "outlined") {
conditionalStyles.border = "5px solid black";
conditionalStyles["&:hover"] = { border: "5px solid grey" };
}
} else {
conditionalStyles.paddingLeft = theme.spacing(4);
}
return {
...conditionalStyles,
paddingRight: theme.spacing(4)
};
}
}
}
}
});
export default function BasicButtons() {
return (
<ThemeProvider theme={theme}>
<Stack spacing={2} direction="row">
<Button variant="text">Text</Button>
<Button variant="contained">Contained</Button>
<Button variant="outlined">Outlined</Button>
<Button startIcon={<SaveIcon />} variant="contained">
Contained with startIcon
</Button>
<Button startIcon={<SaveIcon />} variant="outlined">
Outlined with startIcon
</Button>
</Stack>
</ThemeProvider>
);
}

React-navigation switch theme toggle

i've implemented theming support into my app with react-navigation, as you can see below.
i am using the system theme settings, and my app follows this rule
this is working great, but there's one thing left on my to-do list,
a option to toggle light/dark theme inside my app,
keep this selection, and store it into the user defaults or something like that..
i followed the official docs (https://reactnavigation.org/docs/themes/)
but they don't mention how to switch themes manually.
in my testing i always got a message that the theme prop is read only and cannot be changed manually.
so how to do that?
any help'd be greatly appreciated ;)
App.js
import { NavigationContainer } from '#react-navigation/native';
import { createStackNavigator } from '#react-navigation/stack';
import { AppearanceProvider, useColorScheme, useTheme } from 'react-native-appearance';
const Stack = createStackNavigator();
// ------------------App-----------------------------
export default function App() {
const scheme = useColorScheme();
const MyDarkTheme = {
dark: true,
...},
const LightTheme = {
dark: false,
...}
return (
<AppearanceProvider>
<NavigationContainer theme={scheme === "dark" ? MyDarkTheme : LightTheme}>
<Stack.Navigator>
<Stack.Screen>
name="home"
...
<Stack.Screen
name="Settings"
component={Settings}
/>
</Stack.Navigator>
</NavigationContainer>
</AppearanceProvider>
);
}
in my Components:
import React, { useState, useEffect} from 'react';
import { Card } from 'react-native-elements';
import { useTheme} from '#react-navigation/native';
function CardOne(props) {
const { colors } = useTheme(); // works
const theme = useTheme();
return (
<Card containerStyle={{backgroundColor: colors.cardBackgroundColor, borderColor: colors.borderColor, borderWidth: 2, borderRadius: 5}}>
...
</Card>
);
}
export default CardOne;
i really someone can help me out ;)
You can use the Context and do something like below, basically maintain the theme in state at App.js and update value via context.
export const ThemeContext = React.createContext();
export default function App() {
const [theme, setTheme] = useState('Light');
const themeData = { theme, setTheme };
return (
<ThemeContext.Provider value={themeData}>
<NavigationContainer theme={theme == 'Light' ? DefaultTheme : DarkTheme}>
<Drawer.Navigator initialRouteName="Root">
<Drawer.Screen name="Home" component={HomeScreen} />
<Drawer.Screen name="Root" component={Root} />
</Drawer.Navigator>
</NavigationContainer>
</ThemeContext.Provider>
);
}
You can switch the theme from a screen like below
function ProfileScreen({ navigation }) {
const { setTheme, theme } = React.useContext(ThemeContext);
return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
<Text>Profile Screen</Text>
<Button
title="Switch Theme"
onPress={() => setTheme(theme === 'Light' ? 'Dark' : 'Light')}
/>
</View>
);
}

How to add a style to TextFields in theme provider

I added custom transitions and colors for the textfields and i can pass it to the component with makeStyles hook .
But the problem is every time i want to use the customs i should define it in the component
I want to set it in the theme provider so that it is an static style for all the textfield components
I tried to add in overrides section in the createMuiTheme
Here is what i've tried so far (just the relevant part)
const THEME = createMuiTheme({
overrides:{
"& label.Mui-focused": {
color: "white",
},
"& .MuiInput-underline:after": {
borderBottomColor: "white",
},
}
return (
<div>
<MuiThemeProvider theme={THEME}>
<Header />
<MainPage />
</MuiThemeProvider>
</div>
);
};
Theme provider works fine on the other components
I added MuiTextField element to the overrides element to define the style for textfields
const THEME = createMuiTheme({
overrides: {
MuiTextField: {
root:{
"& label.Mui-focused": {
color: "white",
},

Make the RBSheet reusable as a widget React-Native

I am using RBSheet Package for showing up the bottom sheet in my project. I have understood the concept of how to use it from the documentation. Is there a way that I can make the bottom sheet reusable like a Widget? I have tried doing this:
BottomSheetComponent.js
const BottomSheet = ({ message, buttonText }) => {
// to open this sheet as soon as someone call this Component
this.RBSheet.open();
return(
<RBSheet ref={ ref => { this.RBSheet = ref; }}
customStyles={{mask: { backgroundColor: COLORS.dark }, container: { elevation: 100 }}}>
<View style={styles.messageContainer}>
{/* Add more data later */}
</View>
</RBSheet>
);
}
export default BottomSheet;
MainComponent.js
const MainComponent = () => {
const bottomSheet = () => {
// Trying to call the bottom sheet here
<BottomSheet />
}
return(
<View>
<Button onPress={() => bottomSheet()} title="Bottom Sheet" />
</View>
);
}
export default MainComponent;
I have failed to get the bottom sheet. I have just started working on React Native. I don't want to go with the generic way which is explained in the Package's docs, it is not a good practice to make the same bottom sheet in two different pages from scratch.
So, after a lot of research, I finally figured out what I was doing wrong.
I was using it for the Class Component, although I was using Functional Component
The reference was missing, for which, Metro Build Runner, was giving me errors.
Solution
To solve the issue:
I need to create my own reference
Pass it to the ref props of the Package
MainComponent.js
import React, { useRef } from 'react';
const MainComponent = () => {
// To be used for the reference for the bottom sheet
const sheetRef = useRef();
const bottomSheet = () => {
// Here how you open the bottom sheet right
sheetRef.current.open();
}
return(
<View>
<Button onPress={() => bottomSheet()} title="Bottom Sheet" />
{/* Passing the sheet ref for the binding */}
<BottomSheet sheetRef={sheetRef} />
</View>
);
}
export default MainComponent;
BottomSheet.js
const BottomSheet = ({ sheetRef }) => {
return(
{/* This is the place to make it work */}
<RBSheet ref={sheetRef}
customStyles={{mask: { backgroundColor: COLORS.dark }, container: { elevation: 100 }}}>
<View style={styles.messageContainer}>
{/* Add more data later */}
</View>
</RBSheet>
);
}
export default BottomSheet;
Can you try this?
const bottomSheet = () => {
// Trying to call the bottom sheet here
return <BottomSheet />;
}

MUI customize button color?

I am struggling to modify button colors in MUI next (v1).
How would I set muitheme to behave similarity to bootstrap, so I could just use "btn-danger" for red, "btn-success" for green... ?
I tried with custom className but it doesn't work properly (hover color does't change) and it seems repetitive. What options do I have?
In MUI v5, this is how you create customized colors in your theme for your MUI Button. The primary and secondary colors are created the same way under the hood:
const { palette } = createTheme();
const { augmentColor } = palette;
const createColor = (mainColor) => augmentColor({ color: { main: mainColor } });
const theme = createTheme({
palette: {
anger: createColor('#F40B27'),
apple: createColor('#5DBA40'),
steelBlue: createColor('#5C76B7'),
violet: createColor('#BC00A3'),
},
});
Usage
<Button color="anger" variant="contained">
anger
</Button>
<Button color="apple" variant="contained">
apple
</Button>
<Button color="steelBlue" variant="contained">
steelBlue
</Button>
<Button color="violet" variant="contained">
violet
</Button>
If you're using typescript, you also need to add additional types for the colors you just defined:
declare module '#mui/material/styles' {
interface CustomPalette {
anger: PaletteColorOptions;
apple: PaletteColorOptions;
steelBlue: PaletteColorOptions;
violet: PaletteColorOptions;
}
interface Palette extends CustomPalette {}
interface PaletteOptions extends CustomPalette {}
}
declare module '#mui/material/Button' {
interface ButtonPropsColorOverrides {
anger: true;
apple: true;
steelBlue: true;
violet: true;
}
}

I came up with this solution using Brendans answer in this thread. Hopefully it'll help someone in a similar situation.
import React, { Component } from 'react'
import { MuiThemeProvider, createMuiTheme } from 'material-ui/styles'
import Button from 'material-ui/Button'
import { red, blue } from 'material-ui/colors'
const redTheme = createMuiTheme({ palette: { primary: red } })
const blueTheme = createMuiTheme({ palette: { primary: blue } })
class Buttons extends Component {
render = () => (
<div className="ledger-actions-module">
<MuiThemeProvider theme={redTheme}>
<Button color="primary" variant="raised">
Delete
</Button>
</MuiThemeProvider>
<MuiThemeProvider theme={blueTheme}>
<Button color="primary" variant="raised">
Update
</Button>
</MuiThemeProvider>
</div>
)
}
There is a mistake with Bagelfp's answer, and some other things to consider;
First, 'error' is not a supported color theme in material-ui#next v1's Button component. Only 'default', 'inherit', 'primary' and 'secondary' are accepted by the color prop.
Here is the approach I have found to be the easiest so far. First, choose your two most common theme colors and place them at the root of your app.
import React from 'react';
import { Component } from './Component.js'
import { MuiThemeProvider, createMuiTheme } from 'material-ui/styles';
const theme = createMuiTheme({
palette: {
primary: 'purple',
secondary: 'green',
error: 'red',
},
});
export class App extends Component {
render() {
return (
<MuiThemeProvider theme={theme}>
<Component />
...
</MuiThemeProvider>
);
}
}
Then in your component, choose the theme with your desired color;
import React from 'react';
import Button from 'material-ui/Button';
export const Component = (props) => (
<div>
<Button variant="fab" color="primary">
I am purple, click me!
</Button>
</div>
)
If you need a third and fourth color, you can export Component.js with a new palette just like you did in App.js.
This is the only solution I have found that allows me to retain the darkened hover effect (none of the official override examples retain functioning hover). I really wish I could find a way to simply drop in a new theme color when calling Button, but for now this is the most simple way to do it.
EDIT: My new preferred method is to create a CustomButton component using styled-components and material-ui buttonbase. I also place the styled-components theme provider at the root of my app alongside my MuiThemeProvider. This gives me easy access to additional theme colors in all my styled-components without importing and dropping in more ThemeProviders. In the case of my CustomButton, I just give it a theme prop, which is passed right down to the css in styled(ButtonBase). See the styled-component docs for more info.
Try this:
import * as React from 'react';
import Button, { ButtonProps } from "#material-ui/core/Button";
import { Theme } from '#material-ui/core';
import { withStyles } from '#material-ui/styles';
const styles: (theme: Theme) => any = (theme) => {
return {
root:{
backgroundColor: theme.palette.error.main,
color: theme.palette.error.contrastText,
"&:hover":{
backgroundColor: theme.palette.error.dark
},
"&:disabled":{
backgroundColor: theme.palette.error.light
}
}
};
};
export const ButtonContainedError = withStyles(styles)((props: ButtonProps) => {
const { className, ...rest } = props;
const classes = props.classes||{};
return <Button {...props} className={`${className} ${classes.root}`} variant="contained" />
});
Now you have a ButtonContainedError to use anywhere.
And it is consistent with your theme.
Here is an example typescript implementation:
import React from "react";
import { createStyles, Theme, makeStyles } from "#material-ui/core/styles";
import capitalize from "lodash/capitalize";
import MuiButton, {
ButtonProps as MuiButtonProps
} from "#material-ui/core/Button";
export type ColorTypes =
| "primary"
| "secondary"
| "error"
| "success"
| "warning"
| "default"
| "inherit"
| "info";
type ButtonProps = { color: ColorTypes } & Omit<MuiButtonProps, "color">;
const useStyles = makeStyles<Theme>(theme =>
createStyles({
outlinedSuccess: {
borderColor: theme.palette.success.main,
color: theme.palette.success.main
},
outlinedError: {
borderColor: theme.palette.error.main,
color: theme.palette.error.main
},
outlinedWarning: {
borderColor: theme.palette.warning.main,
color: theme.palette.warning.main
},
outlinedInfo: {
borderColor: theme.palette.info.main,
color: theme.palette.info.main
},
containedSuccess: {
backgroundColor: theme.palette.success.main,
color: theme.palette.success.contrastText,
"&:hover": {
backgroundColor: theme.palette.success.dark
}
},
containedError: {
backgroundColor: theme.palette.error.main,
color: theme.palette.error.contrastText,
"&:hover": {
backgroundColor: theme.palette.error.dark
}
},
containedWarning: {
backgroundColor: theme.palette.warning.main,
color: theme.palette.warning.contrastText,
"&:hover": {
backgroundColor: theme.palette.warning.dark
}
},
containedInfo: {
backgroundColor: theme.palette.info.main,
color: theme.palette.info.contrastText,
"&:hover": {
backgroundColor: theme.palette.info.dark
}
}
})
);
const Button: React.FC<ButtonProps> = ({ children, color, ...props }) => {
const classes = useStyles();
const className = classes?.[`${props.variant}${capitalize(color)}`];
const colorProp =
["default", "inherit", "primary", "secondary"].indexOf(color) > -1
? (color as "default" | "inherit" | "primary" | "secondary")
: undefined;
return (
<MuiButton {...props} color={colorProp} className={className}>
{children}
</MuiButton>
);
};
Button.displayName = "Button";
export default Button;
with this you can do <Button variant="contained" color="success"> with autocomplete and warning free :)
Update:
In Material UI V5 this is achievable in a much more elegant way. You can just add a color to the palette and the button will automatically support it! Their documentation has a great example of how to do this: https://mui.com/customization/palette/#adding-new-colors
You can use theme.palette.getContrastText() to calculate the correct text color based on a background color value.
import { Button, makeStyles } from '#material-ui/core';
const useStyles = makeStyles((theme) => ({
deleteButton: {
// to make a red delete button
color: theme.palette.getContrastText(theme.palette.error.main),
background: theme.palette.error.main,
}
}));
export const DeleteButton = () => {
const classes = useStyles();
return (
<Button className={classes.deleteButton}>Delete</Button>
);
}
first try to install npm install #material-ui/styles the
apply styles according to material documentation, for react class component you can use below code:
import React, {Component} from "react";
import { styled } from '#material-ui/styles';
import Button from '#material-ui/core/Button';
const MyButton = styled(Button)({
background: 'linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)',
border: 0,
borderRadius: 3,
boxShadow: '0 3px 5px 2px rgba(255, 105, 135, .3)',
color: 'white',
height: 48,
padding: '0 30px',
});
class AprinClass extends Component {
render() {
return (
<MyButton>Styled Components</MyButton>
)
}
}
export default AprinClass;

You could create a theme with palettes defined for each of their 3 supported intentions (primary, secondary, error), and then use the color prop on <Button> to use those. In your example the btn-danger could be <Button color='error'>
EDIT: Brendan's answer is correct here that error is not supported for Button. According to the documentation Button only supports intentions that "make sense for this component.", so only primary and secondary would work here.
From their docs (trimmed down a little here):
const theme = createMuiTheme({
palette: {
primary: purple,
secondary: red
}
});
function Palette() {
return (
<MuiThemeProvider theme={theme}>
<div>
<Button color="primary">{'Primary'}</Button>
<Button color="secondary">{'Secondary'}</Button>
</div>
</MuiThemeProvider>
);
}
See Brendan's Answer for a more realistic example of creating themes for your components.
The easiest way to change the button color is to add the "style" attribute. Here's an example of a green button I created:
import Button from '#material-ui/core/Button';
<Button
variant="contained"
color="primary"
style={{ backgroundColor: '#357a38' }}
>
Run
</Button>
From 2022/05:
According to the official Doc: Customize MUI with your theme, you need to use ThemeProvider and createTheme.
First, customize the primary color like this,
import {ThemeProvider, createTheme} from '#mui/material/styles';
const theme = createTheme({
palette: {
primary: {
main: '#000000',
},
},
});
Then wrap your App or anywhere your want with the ThemeProvider component, and set the color props of your Button component to primary.
function YourApp() {
// logic omitted
return (
<ThemeProvider theme={theme}>
<YourApp>
<Button color="primary">Click me</Button>
</YourApp>
</ThemeProvider>
);
}
I found out that !important works in the classes. (React Hooks)
const styles "...etc..." = (theme: Theme) => ({
buttonWarning: {
backgroundColor: theme.palette.warning.dark + '!important'
}
}))
Then in the button
const classes = styles();
<Button className={classes.buttonWarning}>Hello</Button>
Use This sx props it gives more understanding and also more relative to the MUI. in most of the MUI components, they use these props.
import {Button} from '#mui/material'
<Button variant="contained" sx={{
borderRadius: 35,
backgroundColor: "#21b6ae",
padding: "18px 36px",
fontSize: "18px",
**color:"white"**
}} >
elevation
</Button>
Export any color from '#mui/material/colors'; (Docs)
import { pink } from '#mui/material/colors';
and use like this
<Button variant="contained" sx={{ backgroundColor: pink[700] }}>Check</Button>
