Answer 1

Please go to file -> android/app/build.gradle

and edit minSdkVersion from 16 to 21

    defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.google_maps"
    minSdkVersion 21
    targetSdkVersion 30
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

Answer 2

According to it's document you should set the minSdkVersion in android/app/build.gradle:

android {
    defaultConfig {
        minSdkVersion 20
    }
}

Also add this code in the main file :

void main() {
  if (defaultTargetPlatform == TargetPlatform.android) {
    AndroidGoogleMapsFlutter.useAndroidViewSurface = true;
  }
  runApp(MyApp());
}
