Enforce Flutter and Dart best practices across the full development lifecycle: scaffold projects from VGV templates, audit accessibility against WCAG 2.2, manage state with Bloc, structure apps in four-layer monorepos, add i18n/l10n, run golden and widget tests, check dependency licenses, apply OWASP security reviews, upgrade SDKs and lint rules, and automatically analyze and format code on every edit.
Based on adoption, maintenance, documentation, and repository signals. Not a security audit or endorsement.
Audit or remediate Flutter widgets against WCAG 2.2 accessibility conformance levels A, AA, or AAA across iOS, Android, Web, macOS, Windows, and Linux.
Best practices for Flutter animations using the built-in animation framework. Use when creating, modifying, or reviewing animations, transitions, motion, or animated widgets. Covers implicit animations, explicit animations, page transitions, and Material 3 motion tokens.
Best practices for Bloc state management in Flutter/Dart.
Scaffold a new Dart or Flutter project from a Very Good CLI template. Supports flutter_app, dart_package, flutter_package, flutter_plugin, dart_cli, flame_game, and docs_site templates.
VGV-specific reference for bumping Dart and Flutter SDK constraints across packages. Covers pubspec.yaml environment constraints, CI workflow Flutter versions, and SDK upgrade PR preparation. CI uses ^MAJOR.MINOR.x to resolve to the latest patch; pubspec pins the exact patch version (e.g., ^3.50.1).

A [Claude Code][claude_code_link] plugin that accelerates Flutter & Dart development with best-practices skills from [Very Good Ventures][vgv_link].
Developed with 💙 by [Very Good Ventures][vgv_link] 🦄
VGV AI Flutter Plugin is a collection of contextual best-practices skills that Claude uses when helping you write Flutter and Dart code. Each skill provides opinionated, production-quality guidance covering architecture patterns, naming conventions, folder structures, code examples, testing strategies, and anti-patterns to avoid, so you get code that follows [VGV standards][vgv_link] out of the box.
One-line install from your terminal:
claude plugin marketplace add VeryGoodOpenSource/very-good-claude-code-marketplace && claude plugin install vgv-ai-flutter-plugin
Or inside an active Claude Code session, run these as two separate commands (the second only after the first completes):
Add the marketplace:
/plugin marketplace add VeryGoodOpenSource/very-good-claude-code-marketplace
Install the plugin:
/plugin install vgv-ai-flutter-plugin
For more details, see the [Very Good Claude Marketplace][marketplace_link].
| Skill | Description |
|---|---|
| Create Project | Scaffold new Dart/Flutter projects from Very Good CLI templates — flutter_app, dart_package, flutter_plugin, dart_cli, flame_game, and more |
| Animations | Flutter built-in animations — implicit vs explicit decision tree, Material 3 motion tokens (Durations, Easing), page transitions with GoRouter, Hero animations, staggered animations, and performance guidelines |
| Accessibility | WCAG 2.2 compliance with A/AA/AAA conformance level selection across iOS, Android, Web, macOS, Windows, and Linux — semantics, screen reader support, touch targets, focus management, color contrast, text scaling, and motion sensitivity |
| Testing | Unit, widget, and golden testing — mocktail mocking, pumpApp helpers, test structure & naming, coverage patterns, and dart_test.yaml configuration |
| Navigation | GoRouter routing — @TypedGoRoute type-safe routes, deep linking, redirects, shell routes, and widget testing with MockGoRouter |
| Internationalization | i18n/l10n — ARB files, context.l10n patterns, pluralization, RTL/LTR support with directional widgets, and backend localization strategies |
| Material Theming | Material 3 theming — ColorScheme, TextTheme, component themes, spacing systems, and light/dark mode support |
| Bloc | State management with Bloc/Cubit — sealed events & states, BlocProvider/BlocBuilder widgets, event transformers, and testing with blocTest() & mocktail |
| Layered Architecture | VGV layered architecture — four-layer package structure (Data, Repository, Business Logic, Presentation), dependency rules, data flow, and bootstrap wiring |
| Security | Flutter-specific static security review — secrets management, flutter_secure_storage, certificate pinning, Random.secure(), formz validation, dependency vulnerability scanning with osv-scanner, and OWASP Mobile Top 10 guidance |
| UI Package | Flutter UI package creation — custom widget libraries with ThemeExtension-based theming, design tokens, barrel file exports, widget tests, Widgetbook catalog, and consistent API conventions |
| License Compliance | Dependency license auditing — categorizes licenses (permissive, weak/strong copyleft, unknown), flags non-compliant or missing licenses, and produces a structured compliance report using Very Good CLI |
| Dart/Flutter SDK Upgrade | Bump Dart and Flutter SDK constraints across packages — CI workflow versions, pubspec.yaml environment constraints, and PR preparation for SDK upgrades |
| Very Good Analysis Upgrade | Upgrade the very_good_analysis lint package across Dart/Flutter projects — version bump in pubspec.yaml, minimal lint fixes for new rules, and PR preparation |
This plugin includes SessionStart, PreToolUse, and PostToolUse hooks that validate the Very Good CLI, guard against CLI bypass, and automatically run Dart analysis and formatting on .dart files.
