Design and debug Dart asynchronous infrastructure with Future, Stream, isolates, cancellation, and lifecycle-safe ownership. Use for races, stale results, background CPU work, stream leaks, or async error handling; not for routine form-local validation or submission unless its underlying ordering mechanism is the task.

Apply modern Dart language and API patterns in non-concurrency code. Use for types, records, patterns, sealed classes, extensions, constructors, null safety, collections, and package APIs; route async and isolate work to dart-concurrency.

Build or audit Flutter accessibility for semantics, screen readers, focus, keyboard access, text scaling, contrast, target size, and motion preferences. Pair with flutter-responsive-layout when large text causes reflow, clipping, or overflow across constraints.

Build or review provider-neutral AI features in Flutter, including streaming responses, conversation state, structured output, tool calls, attachments, cancellation, and safe service boundaries. Use when model behavior is part of the product; do not use for ordinary APIs, product analytics, or generic chat between people.

Implement or diagnose Flutter motion with implicit, explicit, route, Hero, staggered, and physics-based animations. Use when timing, transition, or motion behavior is requested or broken; route optical materials, shaders, general layout, and performance profiling to their specialists.

Coordinate end-to-end delivery of a complete Flutter app or feature across UI, state, data, tests, bounded implementation review, and runtime verification. Use for broad vertical-slice ownership; not for data-only sync/cache, one screen or form, or contained work that merely touches multiple files or two domains.

Select, review, or evolve Flutter application boundaries, dependency direction, and feature organization. Use for new project structure, scaling problems, or architecture migrations; do not impose a new pattern during a focused feature fix.

Implement, repair, or review Flutter user authentication and session lifecycle, including OAuth or OIDC redirects, PKCE, token refresh, logout, account switching, passkeys, and device re-authentication. Use when sign-in identity or session behavior is the task; route broad threat audits to flutter-security and request transport to flutter-networking.

Implement, debug, or verify Flutter work that must continue or be scheduled after the app leaves the foreground, including OS-scheduled jobs, foreground services, and headless callbacks. Use for persistent background execution; route in-process async or CPU work to dart-concurrency and notification delivery to flutter-notifications.

Configure and verify Flutter flavors, environments, signing, versioning, release artifacts, obfuscation symbols, and store-ready builds. Use for local artifact configuration; route CI provider workflows to flutter-ci-cd, and do not publish or change live credentials without explicit authorization.

Create, repair, or harden provider-neutral Flutter CI/CD pipelines, quality gates, caches, artifacts, secrets, and staged delivery. Use for GitHub Actions, GitLab CI, Codemagic, Bitrise, Xcode Cloud, or similar orchestration; route local artifact configuration to flutter-build-release and never publish without explicit authorization.

Review Flutter and Dart diffs, commits, pull requests, focused code scopes, or completed implementations for concrete defects and regression risks. Use for an explicit change review or bounded delivery review; report evidence without edits. Not for broad threat audits, performance diagnosis, or test authoring.

Plan, execute, or review Flutter and Dart SDK upgrades, dependency resolution, lockfile changes, package breaking changes, and compatible native toolchain migrations. Use when versions or compatibility are the task; route ordinary Dart refactoring to dart-language, security audits to flutter-security, and release artifacts to flutter-build-release.

Operate and verify Flutter apps on a concrete emulator, simulator, browser, desktop, or physical device. Use for target lifecycle, platform-state checks, runtime evidence, and live integration flows; pair with flutter-navigation for route correctness, and do not select it for widget or golden-only work.

Translate an explicit Figma file, frame, component, or node into production Flutter while preserving the app's design system and verifying rendered parity. Use when the request provides or names a Figma source; use flutter-ui-design instead for art direction without Figma.

Implement, repair, or review Flutter purchases of digital goods and subscriptions through app stores, including catalog, transaction updates, verification, entitlements, acknowledgement, consumption, restoration, and sandbox testing. Use for App Store or Google Play billing; not physical-goods checkout, advertising, or generic payment forms.

Implement or review Flutter localization with gen_l10n, ARB resources, plurals, locale-aware formatting, RTL layout, and locale testing. Use for multi-language UI or localization infrastructure; not for arbitrary copy editing.

Implement, review, or verify Flutter routing, deep-link destinations, back-stack behavior, nested navigation, restoration, redirects, and URL synchronization. Use for route correctness; pair with flutter-device-testing on a concrete runtime, and do not introduce a routing package by default.

Build or review Flutter remote data and transport boundaries across HTTP, GraphQL, WebSocket, SSE, or Socket.IO. Use for API contracts, authenticated request transport, pagination, retries, reconnection, caching, and error mapping; route sign-in and session semantics to flutter-authentication and local storage ownership to flutter-persistence.

Implement or repair Flutter local notifications and remote push delivery across permission, scheduling, token, lifecycle, payload, interaction, and reconciliation flows. Use for notification behavior; route ordinary API transport, navigation, persistence, and custom native bridge work to their specialists.
