What is platform channel and why would you need them?

Top 7 YouTube channels I follow for Flutter tutorials

On the client side, MethodChannel enables sending messages that correspond to method calls . On the platform side, MethodChannel on Android ( MethodChannelAndroid ) and FlutterMethodChannel on iOS ( MethodChanneliOS ) enable receiving method calls and sending back a result.

Overall the Platform Channel represents a way to connect native code with the Flutter app (Dart) . It can be used to implement any Flutter missing functionality using a platform-specific code (plugins) and call any APIs whether available in Java or Kotlin code on Android, or in Objective-C or Swift code on iOS.
