🐛 [firebase_app_distribution] In-app tester feedback feature from Firebase App Distribution unable to take screenshots in Flutter apps

Bug report

In-app testers' feedback feature is unable to take a screenshot of the Flutter app. Instead, a black rectangle is shown. Attaching an image from the gallery works as expected. Here is the video of the problem:

The same results are delivered to the Firebase App Distribution dashboard:

Steps to reproduce

Check the sample project for the exact steps.

Expected behavior

I guess product owners would know better, but I assume either the screenshot should be taken immediately or this feature should be disabled.

Sample project

I prepared a repository where this problem is reproducible. The README file contains all the steps performed.

Additional context

I opened a similar issue in the firebase-android-sdk repository. Even though only native android firebase sdk is used in the sample, it was closed with the suggestion to open it here.
