Flutter 应该如何使用颤振web_测试包在颤振web项目上运行单元测试？
我已经在网上探索了一段时间，一切都很好 但是我在为颤振web组件创建单元测试（例如无状态小部件测试）时遇到了问题 我发现有一个名为flatter_web_测试的软件包，但它似乎没有很好地工作 测试代码如下： 我已经安装了颤振web演示项目使用的测试包：Flutter 应该如何使用颤振web_测试包在颤振web项目上运行单元测试？,flutter,flutter-dependencies,flutter-test,flutter-web,Flutter,Flutter Dependencies,Flutter Test,Flutter Web,我已经在网上探索了一段时间，一切都很好 但是我在为颤振web组件创建单元测试（例如无状态小部件测试）时遇到了问题 我发现有一个名为flatter_web_测试的软件包，但它似乎没有很好地工作 测试代码如下： 我已经安装了颤振web演示项目使用的测试包：颤振web\u测试 // import fluter import 'package:flutter_web_test/flutter_web_test.dart'; // a stateless widget is imported import

我应该如何在Flatter_web项目上运行单元测试？他们已经建立了Flatter\u web\u测试包，所以它应该是功能性的。你应该移动到Flatter 1.9，Flatter\u web已被弃用，较短的方法是将Flatter更新到1.9，创建一个新的项目并在其上激活web:
Flatter run-d chromeFlatter build web
