我在运行应用程序时遇到问题。
我的 flutter 细节是:

Flutter 版本:1.12.13+hotfilx.9

在 Visual Studio 中运行 flutter 运行时，它显示了这一点:

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.

* Try:

提前感谢您帮助我。

在主 channel 上创建的 Flutter 项目将生成 android/settings.gradle文件指向 Flutter 工具中存在于 1.18.0-dev.5.0 ( currently available on all channels ) 中的文件。
从 master 切换 -> stable “降级” Flutter 相对于该更改，并且该文件不再存在。
您可以通过重新生成 android/settings.gradle 来解决此问题。在稳定时:

$ rm android/settings.gradle
$ flutter create .
