运行 Flutter 项目后，出现此错误。我能做些什么来解决它？
错误:The method 'setMockMessageHandler' isn't defined for the class 'BasicMessageChannel<dynamic>'.我努力了:flutter pub upgrage这是结果:
No dependencies changed.
1 package is discontinued.
76 packages have newer versions incompatible with dependency constraints.
Try `flutter pub outdated` for more information.
flutter clean
flutter pub upgrade --major-versions
最佳答案
尝试修复你的缓存，它对我有用
flutter pub cache repair
关于android - 没有为类 'BasicMessageChannel<dynamic>' 定义“setMockMessageHandler”，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/69244540/
