Small examples. Real connections.

Start with a single observable. Work up to shared feature state, asynchronous data, and the dependency graph itself. Every example runs real Flutter widgets with MobX, and includes the source that powers it.

Choose an example, then press Run example. The documentation stays lightweight until you choose to load Flutter.

Take the gallery with you

Open the full Flutter app or run flutter run -d chrome -t lib/gallery/main.dart from mobx_examples. Each example is a GoRouter route with a deferred Dart import. The docs embed individual routes using Flutter multi-view; one engine serves the mounted views.
