我正在尝试测试一个使用配置单元库存储数据的数据库类。
我写了这个代码测试：

// import ...
import 'my_datasource_hive_test.mocks.dart';

@GenerateNiceMocks([
  MockSpec<BoxCollection>()
])

void main() {
  test(
    'MyDatasourceHive Constructor',
    () {
      // Assign
      final mockMyCollection = MockBoxCollection();
      final datasource = MyDatasourceHive(
        collection: mockMyCollection,
      );
    },
  );

然后运行生成MockBoxCollection类的命令：
flutter pub run build_runner build
当我运行测试时，我有下一个错误：
The parameter 'boxCreator' of the method 'MockBoxCollection.openBox' has type 'CollectionBox/*1*/<V> Function(String, BoxCollection)?', which does not match the corresponding type, 'CollectionBox/*2*/<V> Function(String, BoxCollection)?', in the overridden method, 'BoxCollection.openBox'.
