+# Platform Channel Samples
+
+A sample app which demonstrates how to use `MethodChannel`, `EventChannel`, `BasicMessageChannel` and `MessageCodec` in Flutter.
+
+## Goals
+
+* Demonstrate how to use `MethodChannel` to invoke platform methods.
+* Demonstrate how to use `EventChannel` to listen continuous value changes from the platform.
+* Demonstrate how to use `BasicMessageChannel` and `MessageCodec` to send messages of different types across the platform.
+
+## The important bits
+
+### [Method Channel demo](./lib/src/method_channel_demo.dart)
+
+Demonstrates how to implement a `MethodChannel` to increment and decrement a
+counter.
+
+### [Event Channel demo](./lib/src/event_channel_demo.dart)
+
+Demonstrates how to implement an `EventChannel` to listen to value changes from
+the Accelerometer sensor from native side.
+
+### [Platform Image demo](./lib/src/platform_image_demo.dart)
+
+Demonstrates how to implement a `BasicMessageChannel` using
+`StandardMessageCodec` to load an image from native asset.
+
+### [Basic Message Channel demo](./lib/src/pet_list_screen.dart)
+
+Demonstrates how to implement `BasicMessageChannel` using `JSONMessageCodec`,
+`BinaryCodec` and `StringCodec` to send and receive data about pets.
+
+## Questions/issues
+
+If you have a general question about Platform Channels in Flutter, the
+best places to go are:
+
+* [The FlutterDev Google Group](https://groups.google.com/forum/#!forum/flutter-dev)
+* [The Flutter Gitter channel](https://gitter.im/flutter/flutter)
+* [StackOverflow](https://stackoverflow.com/questions/tagged/flutter)
+
+If you run into an issue with the sample itself, please file an issue [here](https://github.com/flutter/samples/issues).
