如何在我的颤振项目中识别 BlockProvider？

Question

所以，我最近正在尝试 BLOCK 模式，并且在像这样在我的 pubsec yaml 文件中导入了 block_pattern 包之后

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  bloc_pattern: ^2.2.2+3
  rxdart:

现在，我建立了一个名为 CartListBloc 的类作为 BlockBase 的扩展

class CartListBloc extends BlocBase {
  CartListBloc();
  //etc...

当我尝试将 BlockProvider 放入主类时，尽管导入正确，但 IDE 无法识别它。

import 'package:bloc_pattern/bloc_pattern.dart';
import 'bloc/cartListBloc.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return BlockProvider( // here it doesn't recognize BlockProvider
      blocs: [

      ],
      child:
    );
  }
}

你必须去掉BlocProvider中的k

import 'package:bloc_pattern/bloc_pattern.dart';
import 'bloc/cartListBloc.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return BlocProvider( // remove the K
      blocs: [

      ],
      child:
    );
  }
}
