flutter - 如何在 chrome 平台上运行 flutter 测试？ "No tests ran"尝试启动项目时

Question

为了创建一个 android/web 应用程序，我想在特定平台上运行 flutter 测试。当我指定“chrome”时，我得到“没有运行测试”。当然，当我执行“flutter run -d chrome”时，应用程序正在运行

使用 flutter 启动应用程序很容易重现该问题。这是我在 linux 上所做的:

mkdir chrome_test
cd chrome_test
create .
flutter test test/

=> 所有测试都通过了!

当我在 test/widget_test.dart 开头添加 @TestOn("vm") 时
=> 所有测试都通过了!

当我在 test/widget_test.dart 开头添加 @TestOn("chrome") 时
=> 没有运行测试。
