当项目已经评估时，Flutter 无法运行 Project.afterEvaluate(Closure)

Question

解决方法：看起来有一个信号插件依赖于flutter_tools。解决方法是在“android/app/build.gradle”中依次放置一个signal插件：

apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

将 Flutter 版本从 2.8.1 升级到 2.10 后，我开始收到以下错误。我重新安装了 Flutter，但结果没有改变。当我将 Flutter 降级到 2.8.1 时，它可以正常工作，但是当我升级到 2.10 时，它就不行了。

Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* Where:
Script '/Users/aksoyhlc/flutter/flutter/packages/flutter_tools/gradle/flutter.gradle' line: 421

 What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
   > **Cannot run Project.afterEvaluate(Closure) when the project is already evaluated.**

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

有同样的问题。 仍然没有解决它，但看起来像一个信号插件有问题。如果您将其删除，则一切正常。至少对我来说。

在 OneSignal-Gradle-Plugin 存储库中打开的问题： https://github.com/OneSignal/OneSignal-Gradle-Plugin/issues/184
