URI的目标不存在：flutter_bloc/flutter_bloc.dart＆＃x27;。 Android Studio
我创建了一个全新的扑动项目，我添加了 Bloc： ^8.0.3 和equatable： ^2.0.3 pubspec。 yaml文件，我刚导入导入'软件包：flutter_bloc/flutter_bloc.dart';在主文件中，它给了我上述错误uri的目标不存在：'软件包：flutter_bloc/flutter_bloc.dart'。
我添加了一个cubit文件和导入的导入'package'package'package：bloc/bloc.dart'; ，导入后没有问题，我可以总结'软件包：bloc'和'Flutter'存在，但是'Flutter_bloc'不存在，也不知道为什么，即使我也不存在尝试了许多解决方案，例如删除pubspec.lock和.packages并运行命令flutter pub get code> include> include inclage：package：package：package：package：package： flutter_lints/flutter.yaml ，但问题未解决
I created a brand new flutter project, I added bloc: ^8.0.3 and equatable: ^2.0.3 to pubspec.yaml file, I just imported import 'package:flutter_bloc/flutter_bloc.dart'; in the main file, and it gives me the above error Target of URI doesn't exist: 'package:flutter_bloc/flutter_bloc.dart'.
I added a cubit file and imported import 'package:bloc/bloc.dart'; and no problem happened after importing, I can summarize that 'package:bloc' and 'flutter' exist, but the 'flutter_bloc' not exist, and don't know why, even I tried a lot of solutions like deleting pubspec.lock and .packages and run command flutter pub get, and disable include: package:flutter_lints/flutter.yaml, but the problem not solved

您还应该添加 flutter_bloc package to pubspec.yaml文件，该文件使其易于使用blocs and cubits。
然后运行
flutter Pub获取以获取软件包。You should also add flutter_bloc package to the pubspec.yaml file which makes it easy to use blocs and cubits.
and then run
flutter pub getto get the package.
