Architects Flutter widget trees and Riverpod or Bloc state so rebuilds are scoped, build() stays pure, and const widgets skip recomposition. Use when someone asks "why is my Flutter screen janky", "should I use Riverpod or Bloc", "my whole page rebuilds when one field changes", or is building or refactoring Flutter screens, wiring StatelessWidget/StatefulWidget, Consumer, or BlocBuilder. Do NOT use for Android Jetpack Compose UI - use jetpack-compose-builder instead; do NOT use for React…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Flutter Widget Architect Structure Flutter widget trees and state so rebuilds start and stop exactly where intended and build() is a pure, cheap function of state. The costly failure this prevents is the rebuild storm: one text field changes, the entire screen re-runs build(), the frame budget blows past 16ms (60fps) or 8ms (120fps), and the user sees jank that profiling later traces to architecture, not to any single slow line. ## Operating procedure Order matters: decompose before optimizing subscriptions, because `.select` on a monolithic build() buys nothing. ### Step 1: Gather inputs Before restructuring a screen, establish: 1. The screen or widget in question and where jank or excessive rebuilds appear (default: run DevTools rebuild tracking or `debugPrintRebuildDirtyWidgets` first and capture which widgets rebuild). 2. Existing state management - Riverpod, Bloc, provider, setState, or a mix (a mix inside one feature is itself the finding). 3. Which state is local-ephemeral (a toggle, one text field) vs shared/async/tested. 4. List sizes - anything that can exceed roughly 30 items must be lazy. Label any performance claim not backed by DevTools as a guess. …

How to install
mdr add skillmedev/skills/flutter-widget-architect@sha256:2fd0ab3f4dc71487The line at the top of this page pins the label git:20261005.bea4ea5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
