How do you write a Flutter plugin that communicates with native platform code?

A Set plugin: true in pubspec.yaml and implement all logic in Dart B Define a MethodChannel in Dart, implement MethodCallHandler in native Android (Kotlin) and iOS (Swift) code, and use invokeMethod() to call native functions C Use dart:ffi to call native functions directly without any platform project changes D Extend the FlutterPlugin abstract class and override all inherited platform methods
