我用android建立了一个flutter环境。

之后，我创建了一个新的flutter项目，并试图在上面显示的物理设备(AROFQV5V8LJ，智能手机)上运行该项目，但它不起作用:
$ flutter create key_borrow
$ cd key_borrow
$ flutter run
FAILURE: Build failed with an exception.

BUILD FAILED in 644ms
Running Gradle task 'assembleDebug'... 1,292ms
Exception: Gradle task assembleDebug failed with exit code 1
我已经尝试了所有的方法，包括卸载和重新安装所有的环境。一些我已经尝试过的例子:
$ ./android/gradlew clean
$ ./android/gradlew build
$ flutter clean
$ flutter pub get
$ flutter run
所有这些命令运行没有错误，但当我试图运行或构建应用程序(与flutter cli)，它总是返回相同的错误上面。
此外，我试图将./android/app/build.gradle上的compileSdkVersion和targetSdkVersion更改为版本32(最新)，仍然得到相同的错误。gradle版本也是如此:我做了一些降级，没有任何变化。
我也尝试在android studio上打开项目:它没有显示文件上的任何错误，但当我尝试运行它时，我仍然得到相同的错误。
有人知道吗?

我已经创建了这个新项目多次，总是得到相同的错误。此外，我尝试了这些建议，但我仍然得到同样的错误:
$ flutter create .
$ flutter run
$ rm pubspec.lock
$ flutter pub get
Running "flutter pub get" in key_borrow... 3.8s
$ flutter run
更改gradle版本
我改变文件android/build。gradle: changedcom.android.tools.build:gradle:7.1.2tocom.android.tools.build:gradle:4.1.3
颤振CLI导致相同错误．所以，我试着运行gradle，我得到了这个:
$ cd android
$ ./gradlew clean build
*[Several log lines that I ommitted]*
> Task :app:lint FAILED
FAILURE: Build failed with an exception.
* What went wrong:

Fix the issues identified by lint, or add the following to your build script to proceed with errors:
...
android {
lintOptions {
abortOnError false
}
}
...

执行flutter create .命令，注意创建后有一个句号。这将添加所有缺失的文件。然后尝试构建应用程序。
