Bridge Flutter to native code with confidence. You will learn when native integration is genuinely needed, how MethodChannel carries calls between Dart and Kotlin/Swift, how to return results and errors safely, and how to package it all as a reusable platform plugin.

When (and when not) to drop to native code — free to watch, no account needed.
What you'll learn
- Bridge Flutter to native code using MethodChannel across Android and iOS
- Implement Kotlin and Swift handlers that receive calls and return typed results
- Propagate native errors and platform exceptions back to Dart cleanly
- Stream continuous native data to Dart with EventChannel and Platform checks
- Package native integration as a reusable, federated platform plugin
