I tried the following flutter clean; flutter pub cache repair; flutter pub run build_runner clean; flutter packages pub run build_runner build --delete-conflicting-outputs and didn't work.

My pubspec.yaml

dependencies:
  flutter:
    sdk: flutter
  font_awesome_flutter: ^8.8.1
  responsive_scaffold: ^1.3.0+2
  flutter_bloc: ^6.0.1
  flutter_slidable: ^0.5.5
  hive: ^1.3.0
  hive_flutter: ^0.3.0+1

dev_dependencies:
  hive_generator: ^0.7.0
  build_runner: ^1.7.2
  flutter_test:
    sdk: flutter

dependency_overrides:
  analyzer: '0.39.14'

NOTE:

I tried this yesterday and all was fine but when I upgrade Flutter today, everything crash. The logs says to open the issue here, I know this is a Flutter project, not a Dart project.

Thanks for the report! Two questions:

• are you experimenting with the null safety feature? If so, it's a bit early for that, but you'd want to use a recent flutter sdk from the master channel, not stable
• what happens if you remove the explicit dependency_overrides on package analyzer? It's possible that that's forcing a slightly older version that doesn't handle 2.10 language references when running on a 2.9.1 sdk

[Classy-Bear]

• I'm not experimenting with null safety

When I removed the dependency_overrides I get the following logs...

@Classy-Bear so it looks like the build succeeds now? I am going ahead and close this issue then.

[Classy-Bear]

No it didn't. The logs from above repeats itself. A temporary solution is downgrading to build_runner to 1.10.1 in the stable channel. I will leave this closed because is a duplicate. And it looks like is being trying to be solved.
