I am facing this issue when I run flutter pub run build_runner build. I have tried solutions like flutter clean, flutter pub-cache repair flutter pub get, etc. Dependencies like Mockito, HTTP, and build_runner are added on pubspec and flutter pub get ran successfully as well.

Failed to precompile build_runner:build_runner:

      return kinds.contains(TargetKind.topLevelVariable);

adding the analyser https://pub.dev/packages/analyzer dependency 1.5.0 in the dev-dependencies of pubspec yaml worked for me

 dev_dependencies:
   analyzer: 1.5.0

As stated here: https://github.com/dart-lang/sdk/issues/46136#issuecomment-848910733, you should be able to just run flutter pub upgrade without specifying any analyzer version, and it'll work!

Try add these lines to your pubspec.yaml

dependency_overrides:
   meta: 1.6.0

  • Thank you. I didn't wanted to upgrade to latest version for the moment. This is a good solution for anyone who don't want to upgrade to latest versions for the moment. – Hiran Walawage Dec 20 '21 at 16:17

flutter pub upgrade --major-versions

This will do the thing. Happy coding.

dependency_overrides: analyzer: '1.5.0'

Adding this pubspec.yaml file worked for me

it seems to be an issue with newest verson of analyser. I was able to fix it by just downgrading the version from 1.6.0 to 1.5.0.

dev_dependencies: analyzer: 1.5.0
