Older version of the Android plugin API

Hello dear developers. I am unfamiliar with Flutter - SDK.
I want to build the Canvas LMS application (android) https://github.com/instructure/canvas-android but when I run the "flutter pub get" command, I get this message:
Running "flutter pub get" in flutter_student_embed ... 1,8s
The plugin flutter_crashlytics is built using an older version of the Android plugin API which assumes that it's
running in a full-flutter environment. It may have undefined behaviors when Flutter is integrated into an existing app
as a module.
The plugin can be updated to the v2 Android Plugin APIs by following https://flutter.dev/go/android-plugin-migration.
