Right now I can handle messages when the app is open, minimized, or closed, but when I click on the notification. How to process a message if a user logs into the application without notification?
useEffect(() => { messaging().setBackgroundMessageHandler(async remoteMessage => { handlerMessage(remoteMessage) setInitialRoute('Messenger') }); messaging().onMessage(async remoteMessage => { handlerMessage(remoteMessage); }); messaging() .getInitialNotification() .then(remoteMessage => { if (remoteMessage) { handlerMessage(remoteMessage); setInitialRoute('Messenger') } });}, []);
