Flutter Release apk is not working properly?

Question

I had run this flutter build apk to release my App. Now I had build verison 2 of that.

Now again I want to release my version 2 App.To get the release apk

Answer 1

I hope this can help someone. I ran into a problem that my release version does not works and there are no any error messages in logcat. The problem turned out to be that I had FutureBuilder in which i start Future. By running flutter run it works properly (snapshot.hasData was true), but in release version it was always false. Of course, documentation of the FutureBuilder says that hasData should be false in this case. But in fact in debug mode it has different behaviour.

P.S. Another possible problems: Now my app still not working, but this time i saw on logcat next error:

Unhandled Exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences)

Downgrading gradle plugin version from 7.* to 3.5.4 solves this issue.

classpath 'com.android.tools.build:gradle:3.5.4'
