build_runner showing error The getter 'macroKeyword' isn't defined for the class 'ClassDeclaration'

When I am running build_runner command it is showing me following error:

Failed to build build_runner:build_runner:

Solution

  • Add analyzer: ^5.11.1 to your dev_dependencies and run the following:

    flutter clean

flutter pub get

dart run build_runner build

    Note: If the analyzer version 5.11.1 doesn't work for you, try changing the version and it will work. You can check for the version here https://pub.dev/packages/analyzer/changelog
