feat(ui): migrate Flutter UI library to Next.js 16 (App Router)
...
Migrate all 87 Dart files from /Users/chase/Documents/cozsweet/lib/ui/
to TypeScript React components, replacing Flutter-native features with
Web equivalents and reimplementing the BLoC pattern with React
Context + useReducer.
Highlights
- 1:1 BLoC -> Context+useReducer+side-effects mapping for auth, chat,
user, and sidebar features (4 providers wired in root-providers.tsx)
- 500px MobileShell primitive eliminates per-screen layout boilerplate
- Headless Dialog primitive (createPortal + ESC + scroll lock) powers
quota / pwa-install / username / pronouns / subscription / other-options
dialogs
- New integrations/: facebook-sdk, google-identity, pwa-install,
media-recorder (Web Speech API + MediaRecorder), browser-detect,
chat-websocket (singleton), message-queue (throttled send)
- CSS Modules + existing design tokens (no new styling system);
extended with breakpoints.css and dimensions.css
- Custom hooks: useBreakpoint (useSyncExternalStore),
useFullVisibility (IntersectionObserver), usePwaInstall,
usePullToRefresh
- Vitest + jsdom; 15 unit tests (chat-reducer, auth-validators)
- React 19.2.4, Next.js 16.2.7, Zod 4, lottie-react, classnames
Workarounds
- next.config.ts: experimental.staticGenerationRetryCount = 0 to
bypass Next.js 16.2.7 /_global-error workStore prerender bug
- src/app/global-error.tsx: required Client Component
- src/types/globals.d.ts: centralized window.google / FB /
SpeechRecognition declarations
Routes (/, /splash, /auth, /chat, /chat/deviceid/[deviceId],
/sidebar) all build and lint clean.
