Flutter sample maybe shows code that's not existing in a new Flutter project using Android Studio

Hi team,

in the DevBlogs article "https://devblogs.microsoft.com/surface-duo/get-started-with-flutter-on-surface-duo/"' step 2 containts the following task:

This code should go right below the GeneratedPluginRegistrant.registerWith(flutterEngine); line

Nevertheless if I copy and paste your example source MainActivity.kt including the method below, everything works but it was for me a little confusing to work with this step's task.

The vanilla activity looked like:

package io.github.tscholze.flutter_app3

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {
}
