一段时间以来，我一直在探索颤动的网络，一切都很好。
但是我在为flutter_web组件创建单元测试（例如StatelessWidget测试）时遇到问题。
我发现有一个名为flutter_web_test的软件包，但似乎不能正常工作。
测试代码如下：
我已经安装了flutter_web演示项目使用的测试软件包：flutter_web_test
// import fluter
import 'package:flutter_web_test/flutter_web_test.dart';
// a stateless widget is imported
import 'package:ies2.pms/views/main.dart';
void main() {
testWidgets(
'test whether ',
(WidgetTester tester) async {
// very simple code, create widget in test
await tester.pumpWidget(CYFCustomView(name: 'aaa'));
print('aaa');
},
);
}
然后我开始使用flutter test运行>
然后我收到以下错误：

我应该如何在flutter_web项目上运行单元测试？他们已经构建了flutter_web_test软件包，因此应该可以使用。
