[英]flutter pub run build_runner build not working
运行 flutter pub run build_runner build 时出现此错误。
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()
^^^^^^^^^^^^^

String get displayString {
^^^^^^^^^^^^^
../../snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/meta-1.7.0/lib/meta_meta.dart:91:14: Context: This is one of the extension members.
String get displayString {
^^^^^^^^^^^^^
../../snap/flutter/common/flutter/.pub-cache/hosted/pub.dartlang.org/analyzer-0.41.2/lib/src/error/best_practices_verifier.dart:260:36: Error: The getter 'commaSeparatedWithOr' isn't defined for the class 'List<dynamic>'.
- '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;
这个问题很可能与过时的依赖项有关,我今天也遇到过类似的问题。
运行flutter pub upgrade
,它应该可以工作!
那些遇到这个问题的人,只需覆盖"meta"
依赖项即可。
只需将这些行添加到 pubspec.yaml
dependency_overrides:
meta: 1.6.0
