What is platform channel in Flutter?

A named channel for communicating with platform plugins using asynchronous method calls . Method calls are encoded into binary before being sent, and binary results received are decoded into Dart values.

Overview. 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 …

Simplest Example – Calling Native from Flutter Here we create a method channel object in Flutter, iOS, and Android with the same name. The Android and iOS objects will set a method call handler to receive calls from Flutter . The Flutter code can then call invokeMethod to call the handlers on the native objects.
