Flutter Dart Error: Dart_LookupLibrary: library 'package:home_widget/home_widget_callback_dispatcher.dart' not found

Question

I am using Home Screen Widget the package is here https://pub.dev/packages/home_widget/install

and with flutter run --release I get the following error Dart Error: Dart_LookupLibrary: library 'package:home_widget/home_widget_callback_dispatcher.dart' not found.

but I don't get any error in flutter run --profile and it works.

I cannot publish to the play store without running flutter run in --release mode. What should I do to prevent flutter run --release mode from giving an error?

Error code:

E/flutter (24125): [ERROR:flutter/shell/common/shell.cc(93)] Dart Error: Dart_LookupLibrary: library 'package:home_widget/home_widget_callback_dispatcher.dart' not found.
