react native firebase messaging click notification

Question

I received the notification from the sender, when I click the notification, app opened.

However, the notification return value does not call to the onMessage() function.

From the documentation , function getInitialNotification() is do what I need. But still not get any value from onMessage() when app opened.

  componentDidMount(){
    firebase.messaging().getInitialNotification();
    firebase.messaging().onMessage(function(payload) {
      console.log("Message received. ", payload);
      // ...
    });
  }

Answer 1

As per documentation, getInitialNotification returns Promise, so you should use it like this:

firebase.messaging().getInitialNotification().then( ​initialMessage => {
   console.log("Initial Message: ", initialMessage); 
})
