I've tried several times:
## It works on the second build
flutter clean && flutter build ios/apk --debug || flutter build ios/apk --debug
## Doesn't work
flutter clean && flutter build ios/apk --release || flutter build ios/apk --release
## Doesn't work
flutter build aot --debug --target-platform android-arm64 || flutter build aot --debug --target-platform android-arm64
## Doesn't work
flutter build aot --debug --target-platform ios || flutter build aot --debug --target-platform ios
Considering release build using AOT not JIT build mode, it seems to be related to AOT build mode of Dart for Flutter.
in my case.
flutter packages get and flutter run
the flutter's version is not the same may cause the problem
