# Platform Channel Samples
|
|
|
|
A sample app which demonstrates how to use `MethodChannel`, `EventChannel`, `BasicMessageChannel` and `MessageCodec` in Flutter.
|
|
|
|
This sample is currently being built. Not all platforms and functionality are in place.
|
|
|
|
## 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 `BasicMessageChanngel` 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.
