## What it is
MobX ported to the Dart language, providing transparent functional reactive state management for Dart and Flutter apps. It uses observables, actions, and reactions to automatically keep application state and the UI in sync.

## Use cases
- manage state in a flutter app
- reactive state management for dart
- keep ui in sync with app state automatically
- replace provider or bloc with mobx
- observable computed values in dart
- flutter counter app with reactive state

## When to choose
- building Flutter or Dart apps that want automatic reactive UI updates from state changes
- you prefer the MobX observables/actions/reactions model over bloc or redux
- you want boilerplate-free state management with code generation support

## When to avoid
- you need a state solution with no code-generation or build_runner step
- your team prefers explicit, unidirectional data flow like redux or bloc
- you are not using Dart or Flutter

## Facets
- artifact type: library
- maturity: active
- function: state-management
- domain: mobile-development, frontend, web-development
- platform: cross-platform
- tags: mobx, reactive-programming, observables, flutter-favorite, code-generation, flutter
