Flutter Platform Channels Example

This project is a practical example of how to use Platform Channels in Flutter to communicate between Dart code and native platform code (Android/iOS).

What are Platform Channels?

Platform Channels allow Flutter to communicate with native platform code (Kotlin/Java on Android and Swift/Objective-C on iOS). This is useful when you need to access device-specific features not directly available in Flutter.

Types of Platform Channels used in this project

  • 🔹 MethodChannel: calls native methods and waits for a response. Example: Getting the battery level (based on Flutter’s official documentation).

  • 🔸 EventChannel: receives continuous streams of data from native code. Example: Sensor monitoring (custom example created for this project).

  • ⚪ BasicMessageChannel: exchanges messages more freely, without the traditional request-response structure (not implemented in this example but important to know).
