Categories
Indexed Skills (85)
flutter-app-workflow
Coordinate end-to-end delivery of a complete Flutter app or feature across UI, state, data, tests, 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.
flutter-networking
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.
flutter-observability
Design, implement, or repair production observability in Flutter using operational logs, error and crash capture, breadcrumbs, traces, release context, privacy controls, and verification. Use for diagnosability and incident signals; not product analytics, profiling-only optimization, or a general code review.
flutter-platform-integration
Implement or review Flutter platform channels, Pigeon APIs, FFI and build hooks, native plugin implementations, platform views, add-to-app boundaries, web interop, and native lifecycle integration. Use when Dart must communicate with native platforms; route reusable package APIs, federation, and publication readiness to flutter-package-development.
flutter-security
Threat-model, audit, or harden Flutter and Dart applications against concrete security and privacy risks involving authorization, secrets, sensitive storage, cryptography, WebViews, deep links, platform exposure, or dependencies. Use for security findings and control requirements; route sign-in and session implementation to flutter-authentication.
flutter-architecture
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.
flutter-device-testing
Operate and verify Flutter apps on a concrete emulator, simulator, browser, desktop, or physical device. Use only when a concrete runtime target or device-only behavior is explicit; pair with flutter-navigation for deep-link route or back-stack correctness, and do not select it merely because focused widget or golden tests suffice.
flutter-responsive-layout
Build or repair adaptive Flutter layouts across devices, constraints, breakpoints, overlap, clipping, orientation, and input modes. Use with flutter-accessibility when text scaling causes reflow, clipping, or disappearing controls; not for general widget state architecture.
flutter-testing
Design, write, or review Flutter unit, widget, golden, and integration tests. Use for test strategy, regressions, fakes, async UI behavior, and end-to-end flows; use device testing for operational emulator or hardware control.
flutter-ai-integration
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.

Use for persistent background execution; route in-process async or CPU work to dart-concurrency and notification delivery to flutter-notifications.
flutter-dependency-upgrades
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.
flutter-in-app-purchases
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.
flutter-openapi-client
Discover, inspect, generate, or update Flutter and Dart API clients from Swagger or OpenAPI contracts. Use when spec inventory, operation selection, client generation, or contract drift is the task; route ordinary HTTP behavior to flutter-networking and login or token lifecycle to flutter-authentication.
flutter-package-development
Create, evolve, test, or prepare reusable Dart packages and Flutter plugins for distribution. Use when the package itself, its public API, platform support, federation, example app, compatibility, or publication readiness is the deliverable; route app-owned native bridges to flutter-platform-integration.
flutter-product-analytics
Design, implement, repair, or review product analytics in Flutter using event contracts, identity, consent, funnels, attribution, experiment exposure, delivery semantics, and backend verification. Use for measuring user behavior and business outcomes; not operational logs, crash reporting, profiling, or general UI tracking.

Implement, repair, or review embedded web content in Flutter, including navigation policy, JavaScript bridges, cookies, sessions, file flows, permissions, and WebView lifecycle. Use when a Flutter screen hosts web content; route OAuth sign-in to flutter-authentication, app routes to flutter-navigation, and broad threat audits to flutter-security.
flutter-ci-cd
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.
flutter-code-review
Review Flutter and Dart diffs, commits, pull requests, or focused modules for concrete correctness, lifecycle, architecture, security, accessibility, performance, and test risks. Use when the user explicitly asks for review or audit findings; report actionable evidence without changing code unless a fix is also requested.

dart-concurrency
Design and debug Dart asynchronous infrastructure with Future, Stream, isolates, cancellation, and lifecycle-safe ownership.

flutter-figma-workflow
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.
flutter-ui-patterns
Build and refactor Flutter widgets, forms with stale-safe asynchronous validation and duplicate-submit handling, widget previews, component APIs, and UI state boundaries.
