Calling useNavigation hook from TouchableOpacity inside a DrawerNavigator from react-navigation pkg throwing error, full source on question body

I'm learning react and react-native last 4 days because need build an mobile app and having the following problem when coding a react-native app:
After some research I found a way to embed a TouchableOpacity inside the top bar of DrawerNavigator, just after the hamburger button and it works giving me an alert.
The problem comes when I try to replace the alert with a call to useNavigation().navigate('Login'); from inside it onPress attribute, it throw the error below.
I want mirror the behavior of menu item on the TouchableOpacity doing the navigation.
Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem., js engine: hermes

}

},

fontSize: 20,
margin: 10,
backgroundColor: 'greenyellow',
},
itemNav: {
fontSize: 40,
padding: 10,

},
});

Here navToLogin is a stand alone function, not in a Functional component. Hooks need to be in a functional component to use. The bellow code should work which navToLogin move the function inside a functional component.
const NestedTabBar = props => {
const navigation = useNavigation();
const navToLogin = () => {
navigation.navigate('Login');
}
return (
<>
<TouchableOpacity
style={stl.itemNav}
onPress={
() => {
//Alert.alert('NavigateToLogin');
navToLogin();
}
} >
<Text>[NavigateToLogin]</Text>
</TouchableOpacity>
</>
);
}

React native `input` must be a function received undefined

I have an array which displays a list of jobs with the radio button(each).If I click any radio button I want to get its value so far I'm getting an error input must be a function received undefined. how can I achieve something like this in react native?
Code
import React, {useState} from 'react';
import {View, Text, TextInput, Image,Button,Body,Pressable,ScrollView,Switch} from 'react-native';
export default function Home({ navigation}){
let roles = navigation.getParam('roles')
const [isEnabled, setIsEnabled] = useState(false);
const toggleSwitch = () => setIsEnabled(previousState => !previousState);
const handleClick = (data, e) => {
alert(e.target.value, data);
}
<View>
{
Object.keys(roles).map((key) => {
return (
<View>
<View style={styles.XYQHC}>
<Text>{roles[key]['name']}</Text>
<Switch
trackColor={{ false: "#767577", true: "#81b0ff" }}
thumbColor={isEnabled ? "#f5dd4b" : "#f4f3f4"}
ios_backgroundColor="#3e3e3e"
onValueChange={toggleSwitch}
value={isEnabled}
/>
<input type="radio" name="roles" value={roles[key]['name']} defaultChecked={roles[key]['id'] == 3 ? true : false } onClick={handleClick.bind(this, roles[key]['name'])}/>
</View>
</View>
)
})
}
</View>
};

I had to edit a little bit to make it work and to assume some input data but here is a working example of your code:
import React, { useState, useEffect } from 'react';
import { View, Text, TouchableOpacity } from 'react-native';
function RadioButton({ label, onPress, selected, style }) {
return (
<TouchableOpacity
style={[
{
flexDirection: 'row',
alignItems: 'center',
marginLeft: 12,
marginVertical: 20,
},
style,
]}
onPress={onPress}>
<View
style={{
height: 24,
width: 24,
borderRadius: 12,
borderWidth: 2,
borderColor: '#000',
alignItems: 'center',
justifyContent: 'center',
marginRight: 12,
}}>
{selected ? (
<View
style={{
height: 12,
width: 12,
borderRadius: 6,
backgroundColor: '#000',
}}
/>
) : null}
</View>
<Text>{label}</Text>
</TouchableOpacity>
);
}
export default function Home({ navigation }) {
// let status = navigation.getParam('status');
let status = 2;
// let roles = navigation.getParam('roles');
let roles = [
{
id: 1,
name: 'lawyer',
},
{
id: 2,
name: 'farmer',
},
{
id: 3,
name: 'architect',
},
];
const [isEnabled, setIsEnabled] = useState(false);
const [chosenRole, setChosenRole] = useState(false);
useEffect(() => {
roles.find((role) => {
if (role.id === status) {
setChosenRole(role);
return true;
}
return false;
});
}, []);
const handleClick = (data) => {
console.log(data);
setChosenRole(data);
};
return (
<View style={{ marginTop: 30 }}>
{roles.map((role) => {
return (
<View>
<RadioButton
label={role.name}
selected={role.name === chosenRole.name}
onPress={() => handleClick(role)}
/>
</View>
);
})}
</View>
);
}

Invariant Violation Text string must be rendered within a <Text> component

I'm really sorry to bother you, but I try to learn React-Native. I'm trying to make a weather app and I have this error :

I was asking myself if the problem could be :
{this.props.currentWeather && <WeatherCard currentWeather={this.props.currentWeather} />}
Because it's not inside a Text component...
If you can help, it could be really great :D
If you need other resources, do not hesitate!
Thanks in advance :)

It might be because of this try this:
change
{this.props.currentWeather.name}
to
{this.props.currentWeather.name != undefined ? this.props.currentWeather.name : null}
Similarly do the above thing for {this.props.currentWeather.main.temp}
Hope this helps!

I would like to post my answer if someone has the same problem. The error says that a text string is "outside" a component. However it wasn't the case. It was indentation's problem. So don't forget to pay attention about that :D Expo can be mean !

ReactJS TypeError: this.props. is not a function

I'm building an application, where there is a form presented with different steps. In all the steps but one, I manage to provide the necessary functions as props to make some operations such as 'handleNext', 'handleBack' or 'handleChange'.
Nevertheless, in the last step, represented in the class SuccessForm, when I try to execute the 'handleDownload' function, I get the following error:
TypeError: this.props.handleDownload is not a function
Here it is the SuccessForm.js class:
export class SuccessForm extends Component {
constructor() {
super();
}
download = e => {
e.preventDefault();
this.props.handleDownload();
}
render() {

Try calling super(props) in the constructor:
constructor(props) {
super(props);
}
and passing function with this instance (this.handleDownload) as it is a class property:
<SuccessForm handleDownload={this.handleDownload} />
Update:
You have a bug on the last step when you not passing a property:
activeStep === steps.length ? <SuccessForm handleDownload={this.handleDownload}/>

Assuming that you have a class in your parent Component, what you're missing is the this keyword in the function reference...
case 3:
return <SuccessForm
handleDownload={this.handleDownload}
/>;

React Native Redux causing whole page to render upon calling function

I have an issue with React Native Redux where I am calling a Redux action from the onChangeText function from inside a TextField. Normally, an update like this would only cause the TextField itself to update, however the whole page is being re-rendered upon each call of the function.
Here is the code for the TextField. The method in question is this.props.updateURL(value)
<TextField label='Server'
value={this.props.profile.url}
labelFontSize={textFont(16)}
tintColor='#B3B2B6'
autoCapitalize="none"
autoCorrect={false}
returnKeyType={'next'}
blurOnSubmit={false}
autoFocus={!this.props.profile.edited}
style={styles.inputStyle}
selectionColor={CUSRSOR_COLOR}
editable={!this.props.profile.edited}
onChangeText={async value => {
this.props.updateURL(value)
}}
renderAccessory={()=>{
return(<TouchableOpacity onPress={this.handleScanPress} >
<Image source={ImgScan} style={{height: 25, width: 25, overflow:'visible', marginBottom:20, marginRight: 10}}/>
</TouchableOpacity>);
}}
>
</TextField>
This is for the Redux methods mapStateToProps and mapDispatchToProps:
const mapStateToProps = (state) => {
return {
profile : state.profileReducer,
deviceUid: state.GlobalReducer.deviceUid,
locationsList: state.LogsReducer.locationList,
errorList: state.ErrorsReducer.failedList,
watermarkText: state.GlobalReducer.watermarkText,
alertPresent: state.LogsReducer.alertPresent
}
};
const mapDispatchToProps = (dispatch) => {
return {
updateURL : (url) => dispatch(updateURL(url)),
updateUserName : (userName) => dispatch(updateUserName(userName)),
updatePassword : (password) => dispatch(updatePassword(password)),
updateDeviceName : (deviceName) => dispatch(updateDeviceName(deviceName)),
allFieldsEntered : (url,userName,password) => dispatch(allFieldsEntered(url,userName,password)),
loginDevice: (url,userName,password,deviceName,deviceId,navigation,existingUser) => dispatch(callLoginApi(url,userName,password,deviceName,deviceId,navigation,existingUser)),
updateFailureMessage: (message) => dispatch(updateFailureMessage(message)),
showLoader: () => dispatch(showLoader()),
hideLoader: () => dispatch(hideLoader()),
updateRegistrationSuccess: (value) => dispatch(updateRegistrationSuccess(value)),
checkForInternet: () => dispatch(checkConnectivity()),
getProfileDetails: async(isToken) => await dispatch(fetchProfileDetails(isToken)),
updateLocationSwitch: (value) => dispatch(updateLocationStatus(value)),
updateIsEdit: (value) => dispatch(updateIsEdit(value)),
storeRegistrationFlagInAsync: () => dispatch(storeRegistrationFlagInAsync()),
isDeviceConnected: (value) => dispatch(isDeviceConnected(value)),
requestLocationPermissions: () => dispatch(requestLocationPermissions()),
passwordChanged: (value) => dispatch(updateIsPasswordChanged(value)),
isEditPage: (value) => dispatch(isEditPage(value)),
getDeviceName: () => dispatch(getDeviceName()),
shouldEnableLocation: (value) => dispatch(shouldEnableLocation(value)),
fetchLocationList: () => dispatch(fetchLocations()),
syncRecords: (url,userName,password,locationList,deviceId,isFromError,shouldPresentErrorMsg) => dispatch(syncFailedRecords(url,userName,password,locationList,deviceId,isFromError,shouldPresentErrorMsg)),
fetchFailedRecords: (shouldShowLoader) => dispatch(fetchFailedRecords(shouldShowLoader)),
updateDeviceAction: (action,deviceId,url) => dispatch(performDeviceAction(action,deviceId,url)),
callLogoutApi: (userName,password) => dispatch(callLogoutApi(userName,password)),
syncDeviceActions: () => dispatch(syncDeviceActions()),
syncPendingUpdates: (url,userName,password,deviceId) => dispatch(syncPendingUpdates(url,userName,password,deviceId)),
fetchPendingLocationsList: () => dispatch(fetchPendingLocationsList()),
showPasswordChangeAlert: (alertFlag,navigation) => dispatch(handleUIForPasswordChange(alertFlag,navigation)),
}
}
export default connect(mapStateToProps,mapDispatchToProps)(Profile);
Here are the reducers:
const initialState = {
url: '',
userName : '',
password : '',
deviceName : '',
resourceCode : '',
isDeviceConnected : false,
allFieldsFilled: false,
token: '',
gpsTrackingInterval : 5,
apiPostingInterval : 30,
failureMessage : '',
registered : false,
edited: false,
editPage: false,
isConnected: true,
shouldEnableLocation: false,
resourceDesc: '',
adminEmail: '',
companyName: ''
}
const profileReducer = (state=initialState,action) => {
switch (action.type) {
case actionTypes.UPDATE_URL :
return {
...state,
url: action.payload
}
...
}
This is the Redux action:
export const updateURL = (url) => {
return {
type: actionTypes.UPDATE_URL,
payload: url
};
