I'm using react-native-dropdownalert for my react native app. If a notification comes, the dropdownalert will be shown. How can I detect the tap on the bar?
I saw the official documentation and there is an onClose method. onClose doesn't meet the need above.
Any method I should use or any good react native 3rd party library I can use instead?
version>=4.1.0
onTap prop added in 4.1.0 release.
onTap={() => console.log('User tapped!')}
version<4.1.0
onClose returns data.
data = {type, title, message, action}
action is what you need.
action can be automatic, programmatic, tap or pan
onClose={({ type, title, message, action }) => action === 'tap' && console.log('User tapped!')}

Is it possible to add code to callback function for componentWillUnmount that will stop callback from unmounting? I want to provide message to user that says "are you sure you want to quit?"
BackHandler module could solve your issue in android. For ios, you need to add gestureEnabled: false in react navigation props and bind alert function with back button on header.
I want to clear errorMessage, when we navigate from Sign in to Sign up and vice-versa, for that I tried using onWillFocus but it has been deprecated.
Can anyone suggest me the replacement of onWillFocus?
You can use the original useEffect hook prescribed which gets triggered when a screen is loaded and when a state changes. You can either pass [] parameters so it only runs once or you can use a state to check it.
useEffect(() => {
// do you work here
}, []);
I setup notification system with firebase and react native. It's working fine, but when i receive notification in any state of app(killed, fore or background) and do click notification push me to home screen. I want to go on notification screen when someone click on notification.
How it will possible?
First, you have to add a Firebase Notification listener at the top-level component. I'll suggest placing it in App.js.
Foreground Listener
Background Listener
After that, You have to navigate to a particular screen with the help of a navigation prop. if you place the listener at App.js then you will not have access to the navigation prop since App.js will return the navigation container.
For that, you have to create one helper function like this navigation without prop
e.g.
export const App = () => {
messaging().setBackgroundMessageHandler(async remoteMessage => {
navigate('Notification'); //navigate to notification screen
});
const unsubscribe = messaging().onMessage(async remoteMessage => {
//generate local notification using your preferred library
//handle navigation
})
return <RootNavigator />;
};
I have implemented firebase cloud messaging in my app successfully. But when a new notification appears, my app should open and then redirect to the notifications page from app.js.
The app is showing log info when the notification is clicked but when I try this.props.navigator.push("Notification"); in that function, it shows an error undefined is not an object(evaluating this.props.navigation.push)
I am guessing this is because I haven't yet initialised my stacknavigator but I don't know this for sure. I am using react-navigation in my app.
Here is the function in my app.js that gets called when the notification is clicked.
const notificationOpen = await firebase.notifications().getInitialNotification();
if (notificationOpen) {
const { title, body } = notificationOpen.notification;
console.log('getInitialNotification:');
this.props.navigator.push("Notification");
}
Also, the navigation code is not working even in my render function in app.js so I think props is not initialised in app.js.
Can anyone help me fix this and land me to the notification page?
Considering you have a route called Notification in your stack navigator and also your app.js has access to the navigator's navigation prop, then you might want to use this.props.navigation.navigate('Notification') in case you are using react-navigation.
The problem with your code is this.props.navigation doesn't have any method called push so it will surely give an undefined error. To know more about navigation prop consider going through this doc.
AppState.addEventListener('change', ...)
The listener does not getting any call. I'm using StackNavigator to put root screen and the screen with AppState
(Updated) It's been called when I restart the app. But the Component where I use AppState is not yet the active screen
In my case, I just want to get notified when a navigation come back to or leave a screen. So I can simply do this
this.props.navigation.addListener('didFocus', ...);
this.props.navigation.addListener('didBlur', ...);
The problem with AppState still remains
