Have you worked with integrating native components and Flutter in one project?

Yes, I have worked with integrating native components and Flutter in a single project. This is usually done to utilize platform-specific features that are not yet implemented in Flutter, or for a gradual transition to Flutter.

In Android, this is implemented by creating a Flutter module and connecting it to the native application, or vice versa — adding native views to Flutter via PlatformView.

Example for Android (Kotlin):

// Launching FlutterActivity from a native Android application
val intent = FlutterActivity.createDefaultIntent(context)
startActivity(intent)

For iOS, FlutterViewController can be used to embed Flutter UI into a native application.

This approach allows flexible combination of native and Flutter UI, but requires attention to lifecycle management and communication between layers (for example, via MethodChannel).
