SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps Flutter developers implement Android-native capabilities that Flutter cannot directly access by providing a reliable Kotlin platform-channel integration pattern.

Core Features & Use Cases

  • MethodChannel Architecture: Create thin Kotlin dispatchers with handler registries, lifecycle-aware registration, and Flutter-native communication boundaries.
  • Native Integration Patterns: Handle main-looper execution, engine lifecycle management, notImplemented fallbacks, and native-to-Flutter callbacks.
  • Use Case: Build Android Auto support, foreground services, widgets, or deep operating system integrations while keeping business logic in Dart whenever possible.

Quick Start

Use the kotlin skill to implement a Kotlin MethodChannel handler registry for a new Flutter Android feature.

FAQPage Schema
How do I create a MethodChannel in Kotlin for Flutter native Android integration?

To create a MethodChannel for Flutter native Android integration, you build a thin Kotlin dispatcher with a handler registry that manages Flutter engine communication and lifecycle-aware registration. This pattern establishes a typed boundary for safe native-to-Flutter invocation.

When do I need Kotlin platform channels in a Flutter app?

You need Kotlin platform channels when your Flutter app requires native Android capabilities beyond Dart APIs, such as Android Auto support, foreground services, or deep OS-level integrations. This Skill provides the reliable platform-channel pattern to bridge those features.

What's the best way to handle main-thread execution in Flutter Android native channels?

Handling main-thread execution in Flutter Android native channels requires reliable main-looper execution and lifecycle-aware registration within your Kotlin dispatcher. This ensures safe native-to-Flutter callbacks and proper engine lifecycle management during platform communication.

Can I implement Android foreground services in Flutter using Kotlin?

Yes, you can implement Android foreground services in Flutter by using Kotlin platform channels to bridge the native OS-level feature. This approach keeps your business logic in Dart whenever possible while handling the native integration through a MethodChannel dispatcher.

Why does my Flutter platform channel throw a notImplemented error on Android?

A Flutter platform channel throws a notImplemented error on Android when the Kotlin handler registry lacks a registered handler for the invoked method. Implementing a notImplemented fallback within your MethodChannel dispatcher resolves this native integration gap.

Do I need to keep business logic in Dart when building Flutter native Android integrations?

You should keep business logic in Dart whenever possible when building Flutter native Android integrations. Use Kotlin platform channels strictly as a thin dispatcher to bridge OS-level features, maintaining a typed boundary between native and Flutter layers.
