【中文标题】在 Flutter 中读取“lib/generated_plugin_registrant.dart”时出错【英文标题】：Error when reading 'lib/generated_plugin_registrant.dart' in Flutter 【发布时间】：2020-10-16 21:33:46 【问题描述】：

我是 Flutter 开发的新手。当我尝试使用颤振在本地创建我的应用程序时工作正常。但是，如果我在解决依赖关系后尝试导入其他 repo，它仍然无法正常工作。

我做了什么：

我在 Chrome 中执行应用程序，而不是在设备中。我在 Master 和 Beta 渠道都试过了。我做了 Flutter clean，Flutter pub get 和 delete .vscode 仍然没有解决问题。

错误日志：

【问题讨论】：

通过重新生成 Gradle 文件来解决。我切换到 Android Studio 来解决所有其他依赖项 【参考方案1】：

“读取 'lib/generated_plugin_registrant.dart 时出错” 当您在主通道升级后在 chrome 设备中运行您的 Flutter 应用程序时发生，而不提供 Web 支持。
