android - Flutter项目中 "flutter.minSdkVersion"的值在哪里初始化？

Question

我创建了一个新的 Flutter 项目，这就是 app/build.gradle 中 minSdkVersion 的样子文件:

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.projectname"
    minSdkVersion flutter.minSdkVersion
    targetSdkVersion flutter.targetSdkVersion
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

flutter.minSdkVersion 的值在哪里？放？
请注意，以前，该配置值如下所示:

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.projectname"
    minSdkVersion 19 //*** This is the part that needs to be changed, previously was 16
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

此外，这是 android/local.properties 的内容文件:

sdk.dir=/Users/usernaem/Library/Android/sdk
flutter.sdk=/Users/username/flutter
flutter.buildMode=release
flutter.versionName=1.0.0
flutter.versionCode=1

如您所见，flutter.minSdkVersion 的值那里没有设置，但是项目可以编译构建成功。flutter.minSdkVersion 在哪里和 flutter.targetSdkVersion变量初始化？

转到您的 flutter 提取文件夹中的此文件:
flutter/包/flutter_tools/gradle/flutter.gradle
在那里你可以找到所有的静态变量。
