Best-practice skills for Flutter and Dart covering accessibility, animations, BLoC, testing, theming, navigation, security, internationalization, layered architecture, license compliance, UI packages, project creation, SDK/lint upgrades, and an autonomous quality-gate loop that drives analyze, format, test, and coverage to green — plus automated dart analyze and format hooks.

accessibility Audits or remediates Flutter widgets against WCAG 2.2 conformance levels A, AA, or AAA across iOS, Android, Web, macOS, Windows, and Linux, covering Semantics labels and screen reader output under Voi animations Best practices for Flutter animations using the built-in animation framework, covering implicit animations, explicit `AnimationController` animations, page transitions, and Material 3 motion tokens. bloc Best practices for Bloc state management in Flutter/Dart, covering Cubit versus Bloc, event and state naming, sealed classes with Equatable, the Page/View split with BlocProvider, BlocBuilder, BlocLis Create project Scaffold a new Dart or Flutter project from a Very Good CLI template, covering the flutter_app, dart_package, flutter_package, flutter_plugin, dart_cli, flame_game, and docs_site templates, inferring Dart flutter sdk upgrade VGV-specific reference for bumping Dart and Flutter SDK constraints across packages, covering pubspec.yaml environment constraints, CI workflow Flutter versions, and SDK upgrade PR preparation. Green gate Drives a Dart or Flutter package fully green through an autonomous verify-fix-rerun loop across four quality gates: analyze, format, test, and coverage, exiting only when one final iteration proves al internationalization Best practices for internationalization (i18n) and localization (l10n) in Flutter, using the built-in `flutter_localizations` and `intl` setup with ARB files as the single source of truth. Layered architecture Best practices for VGV layered monorepo architecture in Flutter, covering the four layers Data, Repository, Business Logic, and Presentation, their unidirectional dependency rules, model transformatio License compliance Audits Dart and Flutter package dependency licenses using the Very Good CLI packages_check_licenses MCP tool, flags non-compliant or unknown licenses, and produces a compliance summary report. Material theming Best practices for Flutter theming with Material 3, treating ThemeData as the single source of truth for colors, typography, component styles, and spacing. navigation Best practices for navigation and routing in Flutter using GoRouter, covering hierarchical route trees, type-safe `@TypedGoRoute` definitions, named navigation, redirects, and deep linking setup. Static security Static security review for Flutter mobile apps and Dart code, flagging hardcoded secrets, insecure storage, unsafe network calls, leaky logs, and vulnerable dependencies. testing Best practices for Dart unit tests, Flutter widget tests, and golden file tests, covering descriptive group and test naming, setUp lifecycle and test isolation, mocking and verification with package:m Ui package Best practices for building a Flutter UI package on top of Material, covering custom components, ThemeExtension-based theming, consistent APIs, widget tests, and scaffolding from the app_ui_package te Very good analysis upgrade Upgrade the very_good_analysis lint package to a new version in any Dart or Flutter package, handling the pubspec.yaml version bump, the lint fixes the new rules force, and the PR.
