在Visual Studio中运行Flutter时，它显示如下：

Launching lib\main.dart on CPH1859 in debug mode...

FAILURE: Build failed with an exception.

* Where:
Settings file 'project_name\android\settings.gradle' line: 15

* What went wrong:
A problem occurred evaluating settings 'android'.
> Could not read script '\flutter\packages\flutter_tools\gradle\app_plugin_loader.gradle' as it does not exist.

预先感谢您的帮助。

Answer 1

在主渠道上创建的Flutter项目将生成一个android/settings.gradle文件，该文件指向Flutter工具中存在于1.18.0-dev.5.0中的文件（当前位于master, dev, and beta channels上，但没有稳定）。

从主服务器切换->相对于该更改稳定地“降级” Flutter，并且该文件不再存在。

您可以通过在稳定状态下重新生成android/settings.gradle来解决此问题：

$ rm android/settings.gradle
$ flutter create .

有关更多详细信息，请参见GitHub issue。

Answer 2

只需降级您使用的最新库/软件包，就可以了

Answer 3

只需运行版本项目setting.gradle即可替换当前的setting.gradle文件代码。例如：其他版本项目： android> setting.gradle

此代码将是您当前的flutter版本，只需将您的setting.gradle替换为旧的一个或其他项目

Settings.gradle

r'^[^A-Z]*E[^A-Z]*S[^A-Z ]*(?= )'

Answer 4

将频道从稳定更改为 master 对我有用。

要查看频道：

flutter channel

要更改频道：

flutter channel <channel_name>

例如flutter channel master

运行应用程序时出现错误“ $ flutterSdkpath \ packages \ flutter_tools \ gradle \ app_plugin_loader.gradle”
