我正试图从我的flutter应用程序构建apk，但我遇到了这个错误：

我在谷歌上搜索了一下，发现compileSdkVersion必须是28。这是我的构建渐变应用程序：
android {
compileSdkVersion 28
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "net.mobile"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
storePassword keystoreProperties['storePassword']
}
}
buildTypes {
release {
signingConfig signingConfigs.release
}
}
}
但我还是犯了错误？
