[firebase_messaging] Notification banner not showing on Android

[MichaelM97]

When receiving an FCM from cloud functions in a Flutter app, on iOS the notification appears with a banner and in the system tray as expected. However, on Android the notification appears straight in the system tray without displaying a banner.

Shouldn't the behaviour be the same for both platforms when sending the exact same FCM?

Here is the FCM:

const payload = {
          notification: {
            title: 'You have a new message!',
            body: 'Tap to reply'
          },
          data: {
            click_action: 'FLUTTER_NOTIFICATION_CLICK',
            uid: sendingUserID
          }
        };

const options = {
      priority: 'high'
    };

admin.messaging().sendToDevice(token, payload, options);

Is there additional flag that I can set in options or the payload?

Hi @MichaelM97
could you please provide your flutter doctor -v
and your flutter run --verbose.
Thank you

For flutter run --verbose is there any specific information you're looking for? As the output for that is ~20000 lines. If it's dependency versions, they are as follows

Hello, i am getting this exact same problem. What gives?

[lexyfeito]

Any news on this? i am ran into the same problem.

FCM only displaying notifications when the app in the background or quit, not when in the foreground. You can use the https://pub.dev/packages/flutter_local_notifications to display a banner style notification - the channel must have a high priority.

Leaving open for documentation improvements.

I know all this @Ehesp Elliot. I cant even get it to show up high priority from the fcm console. Can you explain simply how to get it done with the least complication from fcm and ill get it working from whatever stack. Thanks.

[Ehesp]

I cant even get it to show up high priority from the fcm console.

What do you mean by show up high priority? Do you mean when on a different app on the device you want it to appear over the top (as a banner?)

[nicolasvahidzein]

Exactly. Trying for 3 weeks. Impossible.

@Ehesp Any way you can help me with this?
