Sooner or later, every Flutter app hits a wall: a native framework with no `pub.dev` package, an abandoned plugin with dozens of unresolved issues, or a feature like a Live Activity in the Dynamic Island, that Flutter simply cannot render. At that point, you're writing platform code, and most of us do it the worst possible way: a hand-written `MethodChannel` with stringly-typed method names, custom codecs, and no compile-time safety across Dart, Swift, and Kotlin. This talk is about doing it properly with Pigeon, demonstrated through real integrations I built and documented not `getBatteryLevel()`. We begin by looking at why the traditional `MethodChannel` approach breaks down and what Pigeon's generated, type-safe interfaces change. From there, we work through four progressively more complex integrations: AirPlay : Native continuously pushes route and device state back into Flutter. Simple method calls aren't enough; you need event streams that cross the platform boundary cleanly. HealthKit : Native owns permissions and asynchronous authorisation. The platform boundary now has more states than just success and failure, and your API needs to model them explicitly. Live Activities : Native owns the UI, rendered by SwiftUI in a separate process. Flutter is no longer the renderer it becomes a data source. This is the integration that fundamentally changes how many developers think about a Flutter application. Across all of these examples, the underlying pattern is the same and it's the real takeaway from the talk. The complexity of a platform integration isn't determined by the framework you're calling; it's determined by how much responsibility the native platform has taken over. Once you recognise that pattern, you can predict how difficult an integration will be before you write a single line of code. You'll leave knowing how to replace hand-written platform channels with Pigeon, design type-safe APIs that handle errors and event streams gracefully, and confidently integrate native iOS frameworks even when no Flutter package exists.
