当我运行我的应用程序的测试时,我得到了这个异常:
NoSuchMethodError: Attempted to use type 'SimplePipe' as a function. Since types do not define a method 'call', this is not possible. Did you intend to call the SimplePipe constructor and forget the 'new' operator?
我从这条错误消息中得出结论,我的项目实际上不是使用 Dart 2.0 而是使用 Dart 1.0。不过,sdk 设置为>=2.0.0-dev.53.0 <2.0.0
in pubspec.yaml
。
我的一个朋友在他的 PC 上在相同条件下运行相同测试时收到此错误消息。他已经试过跑步了pub get
。
Dart 2.0.0-dev.54.0.flutter-46ab040e58 is incompatible with your dependencies' SDK constraints. Please run "pub get" again
