How to open a link when user clicks on Firebase notification in a Flutter App?

Question

I am using Firebase in a Flutter app. To send notifications, I am using Firebase Messaging plugin. Whenever I send a notification using Firebase website, the notification just opens the app when user clicks on it. I want to send a notification which opens a URL instead of the app.

I don't know if this information is useful: while composing a notification on Firestore, I always put click_action as FLUTTER_NOTIFICATION_CLICK in "Custom data" section in Additional Options.

You can use onLaunch() and onResume() methods to handle notification's opening action.

for more information of notification's reaction on different platforms please see below link: https://pub.dev/packages/firebase_messaging#receiving-messages

 _firebaseMessaging.configure(
       onMessage: (Map<String, dynamic> message) async {
         print("onMessage: $message");
       },
       onBackgroundMessage: myBackgroundMessageHandler,
       onLaunch: (Map<String, dynamic> message) async {
         print("onLaunch: $message");
       },
       onResume: (Map<String, dynamic> message) async {
         print("onResume: $message");
       },
     );

And you can use url_launcher to open URLs: https://pub.dev/packages/url_launcher
