Platform Channel Sample App

The samples repo in the flutter is a place where every Flutter enthusiast can find flutter examples on various topics from animation to state management. One of the interesting things which Flutter provides is Platform channels for communicating between your Dart code and the platform-specific code of your host app. The current folder add_to_app has a few apps that touch on platform channels, but nothing dedicated to the topic. The repo also misses out for the examples showing how to bind the native C/C++ code in Flutter. The idea is to create samples which demonstrate use of EventChannel, MethodChannel, BasicMessageChannel, MessageCodec, AndroidView, and also binding the native C/C++ code in Flutter
