当我运行flutter build apk -v时，我看到以下输出：

当我这样更改（android \ app）build.gradle时，将显示相同的输出。
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
buildTypes {
release {
signingConfig signingConfigs.release
useProguard true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
我认为androidx有问题，但我不知道该怎么办。
我第一次成功迁移androidx时就尝试了迁移，但是当我再次尝试时，他们说项目中未找到任何用法，因此我不能再做一次
其他信息： 我使用了android studio，并升级了所有内容。 gradle，sdkversion（到29）distrubuturl（到5.4.1）并还添加了android.useAndroidx = true
