In Episode 6 of "How Flutter Works," Craig takes us beneath the Dart code to explore the Flutter engine and embedders. This episode explains how Flutter mobile apps rely on native Android and iOS code to launch and operate, how the Flutter engine connects your Dart code to the host platform, and how embedders facilitate communication between the two. Craig also highlights the structure of a newly generated Flutter project, dives into how threads are managed in a Flutter app, and explains the roles of PlatformChannels and the Pigeon package.
You’ll also learn why the Flutter engine is written in C++ rather than Dart, how it evolved from a fork of Chrome, and how it uses Skia or Impeller to render each frame. The episode wraps up by looking ahead to Flutter's future architecture improvements, which aim to simplify native interop even further. If you want a clear mental model of how Flutter apps work under the hood, this is the perfect way to connect all the layers together.
