Platform channels are Flutter's mechanism for communicating between Dart code and native platform code (iOS/Android) — letting Flutter access native features or existing native code not available through Dart packages. They bridge Flutter to the underlying platform.
Why platform channels exist
Flutter (Dart) can't directly access every native platform feature. Platform channels
let Dart call NATIVE code (Kotlin/Java on Android, Swift/Objective-C on iOS):
→ access native APIs/SDKs not covered by existing plugins
→ use existing native libraries or platform-specific functionality
→ integrate with native code in a hybrid app
→ The bridge between Flutter and the native platform.
