评估根项目“android”时出现问题。 配置项目 ':app' 时出现问题

Question

我正在尝试构建一个运行flutter build apk --split-per-abi 的 apk ，我收到以下消息：

请注意，一周前没有发生这种情况。

FAILURE: Build failed with an exception.

* Where:
Script 'C:\sandbox\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 646

* What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
   > The value for this property cannot be changed any further.

* 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.

* Get more help at https://help.gradle.org

BUILD FAILED in 4s
Running Gradle task 'assembleRelease'...
Running Gradle task 'assembleRelease'... Done                       5,5s
Gradle task assembleRelease failed with exit code 1

然后我运行flutter doctor -v以查看 android 和 flutter 是否已过时。

更新并重新启动 Android Studio 后，我遇到了同样的错误。 知道可能是什么问题吗？
