mobx-dart

> The skill is based on mobx v2.6.0 / flutter_mobx v2.0.4, generated at 2026-03-30. MobX.dart is a reactive state management library for Dart and Flutter built around three core concepts: Observables (reactive state), Actions (state mutations), and Reactions (side-effects). It uses `mobx_codegen` for annotation-based code generation to minimize boilerplate. ## Core References | Topic | Description | Reference | |-------|-------------|-----------| | Store & Code Generation | Store class pattern, annotations, build_runner setup | [core-store-and-codegen](references/core-store-and-codegen.md) | | Observables | Observable, Computed, @observable, @readonly, @computed, reactive extensions | [core-observables](references/core-observables.md) | | Actions | @action, runInAction, untracked, transaction, async actions | [core-actions](references/core-actions.md) | | Reactions | autorun, reaction, when, asyncWhen, custom schedulers | [core-reactions](references/core-reactions.md) | ## Features ### Flutter Integration | Topic | Description | Reference | |-------|-------------|-----------| | Observer Widget | Observer, Observer.withBuiltChild, ReactionBuilder for reactive UI | [features-observer-widget](references/features-observer-widget.md) | | Reactive Collections | ObservableList, ObservableMap, ObservableSet, ObservableFuture, ObservableStream, Atom | [features-reactive-collections](references/features-reactive-collections.md) | ## Best Practices | Topic | Description | Reference | |-------|-------------|-----------| | Store Organization | Widget-Store-Service triad, store hierarchy, inter-store communication, Provider integration | [best-practices-store-organization](references/best-practices-store-organization.md) | | Reactivity Rules | When MobX reacts, tracking pitfalls, Observable vs plain collections, form validation pattern | [best-practices-reactivity-rules](references/best-practices-reactivity-rules.md) | | JSON Serialization | json_serializable integration with custom converters for observable collections | [best-practices-json-serialization](references/best-practices-json-serialization.md) | ## Advanced | Topic | Description | Reference | |-------|-------------|-----------| | Context & Config | ReactiveContext, ReactiveConfig, read/write policies, error boundaries | [advanced-context-and-config](references/advanced-context-and-config.md) | | Spy (Debugging) | Spy API for tracing reactive events and debugging | [advanced-spy](references/advanced-spy.md) |
