How to initiate the launch of FlutterActivity in your application?

To launch FlutterActivity in an Android application, you need to create an Intent and start it from a context (for example, from an Activity).

Example code in Kotlin:

import io.flutter.embedding.android.FlutterActivity

// Launch FlutterActivity
val intent = FlutterActivity.createDefaultIntent(context)
context.startActivity(intent)

If you need to pass an initial route or other parameters, you can use methods to create an Intent with additional arguments, for example:

val intent = FlutterActivity.withNewEngine()
    .initialRoute("/myRoute")
    .build(context)
context.startActivity(intent)

Thus, FlutterActivity is launched like a regular Android activity.
