when running flutter pub run build_runner build I get this error.
Failed to build build_runner:build_runner:
../../snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/analyzer-0.41.2/lib/src/error/best_practices_verifier.dart:258:50: Error: The property 'displayString' is defined in multiple extensions for 'TargetKind' and neither is more specific.
- 'TargetKind' is from 'package:meta/meta_meta.dart' ('../../snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/meta-1.7.0/lib/meta_meta.dart').
Try using an explicit extension application of the wanted extension or hiding unwanted extensions from scope.
var kindNames = kinds.map((kind) => kind.displayString).toList()

- 'List' is from 'dart:core'.
Try correcting the name to the name of an existing getter, or defining a getter or field named 'commaSeparatedWithOr'.
var validKinds = kindNames.commaSeparatedWithOr;
This issue is related to outdated dependencies most likely, I had a similar one just today.
Run flutter pub upgrade and it should work!
