Individual skill
flutter
Use when building, structuring, testing or optimizing a Flutter app — feature-first layering, Riverpod 3 or Bloc, typed go_router, freezed models, a dio data layer, Material 3, jank hunting, widget/golden tests. Targets Flutter 3.44 / Dart 3.12. NOT React Native (that is `react-native`), NOT Compose Multiplatform (that is `compose-multiplatform`).

# Flutter & Dart app architecture
The opinionated default stack for a production Flutter app: **feature-first + layered** folders,
**Riverpod 3** with codegen for shared/async state, a **typed go_router**, **freezed** immutable
models, a **dio** data layer, and explicit `Result<T, Failure>` error modeling — all on **Material 3**.
Escape hatches are first-class: **Bloc/Cubit** instead of Riverpod when the team already runs Bloc,
and raw `http`/`get_it` are allowed — but **pick one of each per app, never mix two**. Pinned versions
this skill targets: **Flutter 3.44 / Dart 3.12**, **Riverpod 3.0**, **go_router 17.2.x**
(+ `go_router_builder 4.3.x`), **freezed 3.x** / `json_serializable`, **dio 5.x**, **mocktail 1.x**.
## Boundaries
> **⚠<U+FE0F> SDD new-feature gate — read this first.** If this skill fired on a **new, non-trivial feature or behaviour change** and there is **no approved spec + plan** under `02-DOCS/wiki/sdd/`, STOP — do **not** write feature code yet. Hand off to `../specify/SKILL.md` first: it runs brainstorm → spec → plan → tasks before any code, then routes back here once the plan is approved. Build here directly only for a genuinely one-line / low-risk change. Method: `../asdd/SKILL.md`.
