React Native, content going under navigation header, SafeAreaView not working

As you can see in the image below, I have to give some top margin in order to "not" hide my half of the content under the navigation header, isn't header supposed to be a "safe area" for the below content, to be on the safe side I provided the SafeAreaView but still my content goes under the Header and unfortunately I have to give some hardcoded margin top value to avoid hiding.
The above image is when I comment marginTop.
Above image is when I add marginTop: 70
Code:
NotificationScreen.tsx:
import {
View,
SafeAreaView,
Text,
StatusBar,
} from 'react-native';
import Animated, {FadeIn, FadeOut} from 'react-native-reanimated';
import OrderItem from '../../components/OrderItem';
const NotificationScreen = () => {
const [orders, setOrders] = useState([]);
useEffect(() => {
// calling API...
}, []);
return (
<SafeAreaView style={styles.container}>
<StatusBar backgroundColor="transparent" translucent />
<Text style={{color: 'lightgray', fontSize: 18}}>My Orders: </Text>
<Animated.FlatList
data={orders}
entering={FadeIn}
leaving={FadeOut}
contentContainerStyle={{
alignItems: 'center',
}}
keyExtractor={(_: any, index) => 'key' + index}
renderItem={({item}) => <OrderItem key={item.id} data={item} />}
/>
</SafeAreaView>
);
};
const styles = StyleSheet.create({
container: {
marginTop: 70, // if I remove this, the content goes under the header as shown in image.
flex: 1,
padding: 10,
backgroundColor: COLORS.primary,
},
});
export default NotificationScreen;
One more query, why my OrderItem not taking the full width of FlatList (see image, the gray box is not takin the full width...), I have provided width: 100% to my OrderItem container:
OrderItem.tsx:
const OrderItem = ({data}) => {
return (
<View style={styles.container}>
<View style={styles.textBlock}>
<Text style={styles.label}>Strategy: </Text>
<Text style={styles.info}>{data.strategyTitle}</Text>
</View>
// ... same views as shown in image
</View>
);
};
const styles = StyleSheet.create({
container: {
width: '100%',
paddingVertical: 10,
paddingHorizontal: 10,
alignItems: 'center',
justifyContent: 'space-between',
backgroundColor: COLORS.lightGray,
borderRadius: 10,
},
textBlock: {
flexDirection: 'row',
alignItems: 'center',
justifyContent: 'space-between',
},
label: {
color: 'grey',
fontSize: 16,
},
info: {
color: 'white',
fontSize: 16,
},
});
export default OrderItem;

The SafeAreaView does not work currently for Android devices. You need to have something like this to avoid this issue:
import { Platform,StatusBar } from "react-native";
const styles = StyleSheet.create({
container: {
paddingTop: Platform.OS == "android" ? StatusBar.currentHeight : 0,
},
});
<SafeAreaView style={styles.container}>
</SafeAreaView>
And for the OrderItem not taking all available width, remove from Animated.FlatList this:
contentContainerStyle={{alignItems: 'center'}}

TypeError: undefined is not a function (near '...currencyFilter.map...')

I'm quite new to react native and trying to set up a search bar with search functionality. I'm trying to set it up where the list updates with each letter typed. The data is displayed fine but the error occurs when I try and type something into the search bar.

with hooks you don't pass the state object like setState, you just pass the new value
change
setSearch({
filterCurrency: datas.filter(i => i.name.toLowerCase().includes(searchFor.toLowerCase)),
});
to
setSearch( datas.filter(I =>i.name.toLowerCase().includes(searchFor.toLowerCase)));

Adding a DOM element with the press of a button in react native

I want to be able to add a <Text> element with the press of a button in react native
Is this possible to make ? and how can i do it ?
my code :
import React, { Component } from 'react'
import { StyleSheet, Text, View, Button } from 'react-native'
export default class App extends Component {
onPress = () => {
//some script to add text
}
render() {
return (
<View style = { styles.container }>
<View style = { styles.ButtonContainer }>
//i want to add text here
<Button
onPress={this.onPress}
title="Add item"
color="#FB3640"
accessibilityLabel="Add item"
containerViewStyle={{width: '100%', marginLeft: 0}}
/>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'column',
justifyContent: 'space-between',
backgroundColor: '#fff',
alignItems: 'center',
},
text: {
marginTop: 100,
},
ButtonContainer: {
margin: 20,
width: '90%',
}
});
Thank you !

You need to define a piece of state and initialized it with false. When the user presses the button you have to switch this piece of state to true. Have a look here for more information about the local state: https://reactjs.org/docs/state-and-lifecycle.html#adding-local-state-to-a-class
Something like that should work:
import React, { Component } from 'react'
import { StyleSheet, Text, View, Button } from 'react-native'
export default class App extends Component {
state = {
displayText: false
}
onPress = () => {
this.setState({ displayText: true });
}
render() {
return (
<View style = { styles.container }>
<View style = { styles.ButtonContainer }>
{displayText && <Text>This is my text</Text>}
<Button
onPress={this.onPress}
title="Add item"
color="#FB3640"
accessibilityLabel="Add item"
containerViewStyle={{width: '100%', marginLeft: 0}}
/>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'column',
justifyContent: 'space-between',
backgroundColor: '#fff',
alignItems: 'center',
},
text: {
marginTop: 100,
},
ButtonContainer: {
margin: 20,
width: '90%',
}
});

react native - Passing navigation props from parent to child

I'm trying to create a simple-ish mobile app, but I'm pretty new to this. I've spent some time searching about the errors I'm getting. It seems like a common problem, but they all had the same/similar solutions but the solutions didn't work for me.
What is I'm trying to do? Right now the app is two pages, the home screen (Overview Cards) and the Add Card screen.
There's a button on the Overview Cards that takes you to Add Card.
Add Card allows you to fill out some TextInput boxes and
Add Card should allow you to press the save button and be taken back to the Overview Card screen and see the data you entered in the form.
However, I am getting stuck at Step 3. I am trying to make the Save button navigate the user back to Overview Cards, but there are simply errors instead.
Below is my code, the errors I'm getting, and then what I've tried.
App.js
import React from 'react';
import { StyleSheet, Text, TextInput, View, Button, TouchableOpacity, ShadowPropTypesIOS } from 'react-native';
import AddCard from './components/AddCard.js';
import { NavigationContainer } from '#react-navigation/native';

import { useNavigation } from '#react-navigation/native';
function HomeScreen({ navigation }) {
return (
<View style={styles.homeContainer}>
<Button title="Add Card" onPress={() => navigation.navigate('Add Card')}/>
{/* <Text value={this.props.inputValFT}/> */}
<Text style={styles.textStyle} >VISA xxxx</Text>
<Text style={styles.textStyle}>MASTERCARD xxxx</Text>
<Text style={styles.textStyle}>AMEX xxxx</Text>
</View>
);
}
function AddCardScreen() {
return (
<View style={styles.addCardContainer}>
<AddCard navigation={this.props.navigation} /> // **HERE**
</View>
);
}
const Stack = createStackNavigator();
function App() {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={HomeScreen} options={{ title: 'Overview Cards' }} />
<Stack.Screen name="Add Card" component={AddCardScreen} />

}

The errors I'm getting:
In App.js you can see the ** HERE ** that I put in. When I try to run this, the app loads fine until I click the "Add Card" button. I get this error: undefined is not an object (evaluating 'this.props.navigation').
If I take the navigate={this.props.navigation} part out from App.js, the app loads as it's meant to again, but this time I can click the "Add Card" button and reach the next screen with no issue. I fill out the form (TextInput parts in AddCard.js), but when I click the "Save" button, the app crashes. The error is: TypeError: undefined is not an object (evaluating 'navigation.navigate'). Most likely because of what I'm doing with onPress where it says ** HERE 2 ** in AddCard.js. handleSubmit() is currently commented out, but it used to be inside the onPress.
What I've tried:
Some of the answers I saw were that I need to pass in navigation from the parent to the child and that will make it work. By trying that, I get the errors I mentioned earlier. I also saw that someone mentioned using "withNavigation" or "useNavigation" which was supposed to allow the child to access navigation, but that didn't work for me either. Below are some of the links that I was trying to follow.
How do I pass navigation props from parent component to header?
Pass navigation.navigate to Child Component
https://reactnavigation.org/docs/use-navigation/
Thank you for reading, hopefully my explanation is clear enough.

I think your problem is somewhere here:
function AddCardScreen({ navigation }) {
return (
<View style={styles.addCardContainer}>
<AddCard navigation={navigation} />
</View>
);
}
There is no this, you're not in a class component, therefore this doesn't exists
The prop you are trying to pass should be called navigation and not navigate, since that's how you try to access it in the child component.
The navigation prop needs to be destructured inside the function argument function AddCardScreen({ navigation }), same as you already do for HomeScreen.

Center text below image in react native

I'm trying to center the Edit text below the image. This the start of the profile page for an app I'm working at so I want the Edit button text to be centered below the image.
Here's the code:
import React from 'react';
import { AppRegistry, StyleSheet, Text, View, Image, TextInput, TouchableHighlight, Alert, Button } from 'react-native';
import { Constants, ImagePicker } from 'expo';
const util = require('util');
export default class TopProfile extends React.Component{
state = {
image: 'https://www.sparklabs.com/forum/styles/comboot/theme/images/default_avatar.jpg',
};
render() {
let { image } = this.state;
return (
<View style={styles.container}>
<View style={styles.column}>
<TouchableHighlight onPress={this._pickImage}>
{image &&
<Image source={{ uri: image }} style={{ width: 100, height: 100, borderRadius: 50}} />}
</TouchableHighlight>
<Button
style={styles.button}
title="Edit"
onPress={this._pickImage}
/>
</View>
</View>
);
}
_pickImage = async () => {
let result = await ImagePicker.launchImageLibraryAsync({
allowsEditing: true,
aspect: [4, 3],
});
console.log(result);
if (!result.cancelled) {
this.setState({ image: result.uri });
}
};
}
const styles = StyleSheet.create({
container: {
flex: 1,
flexDirection: 'row'
},
column:{
flex: 1,
flexDirection: 'column',
alignItems: 'flex-start',
paddingLeft: 10,
},
button: {
}
});
module.exports = TopProfile;
And this is what I'm currently getting:
Does anyone have an idea how can I fix this?

There's an error in your column style props.
You've defined alignItems: 'flex-start'. When the flexDirection: 'column', the alignItems prop effects the X-axis of the view, EG how items in the view are horizontally positioned. Setting their alignment to flex-start is not what you want here.
Change your styles to:
column:{
flex: 1,
flexDirection: 'column',
alignItems: 'center', //THIS LINE HAS CHANGED
paddingLeft: 10,
},

it's either you specify the with of the <View style={[styles.column, {width:100, justifyContent:'center'}]} or you wrap your <TouchableHighlight> and <Button> inside another <View>
