[Firebase In App Messaging] Request update version Firebase in app messaging

[TaiHK]

The current version of firebase inapp-mesaging for android on flutter is:

com.google.firebase: firebase-inappmessaging-display: 18.0.2

On: > https://pub.dev/packages/firebase_in_app_messaging

https://github.com/FirebaseExtended/flutterfire/blob/master/packages/firebase_in_app_messaging/android/build.gradle

It will be faulty:
Firebase InApp Messaging not working with Android OS 6.0.1
https://github.com/firebase/firebase-android-sdk/issues/630

But on the latest version it has been fixed:

I'm currently not seeing this error on the latest version of inappmessaging-display (19.0.3). In case you're still having issues, please let me know so I can continue on with the investigation.

implementation 'com.google.firebase:firebase-inappmessaging-display:19.0.4'

Please update to the latest version.
