Flutter Version 2.8.1 causes error running "flutter pub get"

The plugin `flutter_wallet` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2
embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding:
https://flutter.dev/go/android-plugin-migration.

flutter --version

Flutter 2.8.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 77d935af4d (4 weeks ago) • 2021-12-16 08:37:33 -0800

I propose to fix this issue or to add the flutter version which is required to build to the documentation.
