【中文标题】Flutter Web：在 Flutter 运行时在注入的 client.js 脚本中检测到未处理的错误

【英文标题】：Flutter Web: Unhandled error detected in the injected client.js script on flutter run

【发布时间】：2021-01-31 05:36:10

【问题描述】：

运行flutter run -d chrome 时出现以下错误。我无法弄清楚这个错误来自哪里。我尝试了here 中的解决方案，但没有改变任何东西。

医生总结（要查看所有详细信息，请运行 flutter doctor -v）：[✓] Flutter（通道未知，1.20.2，在 Linux 上，语言环境 en_CA.UTF-8）[✓] android 工具链 - 为 Android 设备开发（Android SDK 版本 30.0.0) [✓] Chrome - 为网络开发 [✓] Android Studio（4.0 版）[✓] 连接设备（4 个可用）

你能帮忙吗？

client.js:3316 Unhandled error detected in the injected client.js script.

You can disable this script in webdev by passing --no-injected-client if it
is preventing your app from loading, but note that this will also prevent
all debugging and hot reload/restart functionality from working.

The original error is below, please file an issue at
https://github.com/dart-lang/webdev/issues/new and attach this output:

【参考方案1】：

Chrome 的更改似乎导致了已通过更改 Dart SDK 解决的问题。

flutter upgrade 将为您提供可以解决此错误的最新 Dark SDK。

More information 在 Github 上的 SDK update

【讨论】：

我遇到了同样的问题，升级颤振后错误消失了。我遇到错误时的 Flutter 版本（Channel beta，1.19.0-4.3.pre，在 Microsoft Windows 上）我当前的版本是 Channel beta，1.23.0-18.1.pre，在 Microsoft Windows 上。
