Flutter Development Guide
A practical guide for building cross-platform applications with Flutter 3 and Dart. Focuses on proven patterns, state management, and performance optimization.
Quick Reference
Widget Patterns
| Purpose | Component |
|---|---|
| State management (simple) | StateProvider + ConsumerWidget |
| State management (complex) | NotifierProvider / Bloc |
| Async data | FutureProvider / AsyncNotifierProvider |
| Real-time streams | StreamProvider |
| Navigation | GoRouter + context.go/push |
| Responsive layout | LayoutBuilder + breakpoints |
| List display | ListView.builder |
| Complex scrolling | CustomScrollView + Slivers |
| Hooks | HookWidget + useState/useEffect |
| Forms | Form + TextFormField + validation |
Performance Patterns
| Purpose | Solution |
|---|---|
| Prevent rebuilds | const constructors |
| Selective updates | ref.watch(provider.select(...)) |
| Isolate repaints | RepaintBoundary |
| Lazy lists | ListView.builder |
| Heavy computation | compute() isolate |
| Image caching | cached_network_image |
Core Principles
Widget Optimization
- Use
constconstructors wherever possible - Extract static widgets to separate const classes
- Use
Keyfor list items (ValueKey, ObjectKey) - Prefer
ConsumerWidgetoverStatefulWidgetfor state
State Management
- Riverpod for dependency injection and simple state
- Bloc/Cubit for event-driven workflows and complex logic
- Never mutate state directly (create new instances)
- Use
select()to minimize rebuilds
Layout
- 8pt spacing increments (8, 16, 24, 32, 48)
- Responsive breakpoints: mobile (<650), tablet (650-1100), desktop (>1100)
- Support all screen sizes with flexible layouts
- Follow Material 3 / Cupertino design guidelines
Performance
- Profile with DevTools before optimizing
- Target <16ms frame time for 60fps
- Use
RepaintBoundaryfor complex animations - Offload heavy work with
compute()
Checklist
Widget Best Practices
-
constconstructors on all static widgets - Proper
Keyon list items -
ConsumerWidgetfor state-dependent widgets - No widget building inside
build()method - Extract reusable widgets to separate files
State Management
- Immutable state objects
-
select()for granular rebuilds - Proper provider scoping
- Dispose controllers and subscriptions
- Handle loading/error states
Navigation
- GoRouter with typed routes
- Auth guards via redirect
- Deep linking support
- State preservation across routes
Performance
- Profile mode testing (
flutter run --profile) - <16ms frame rendering time
- No unnecessary rebuilds (DevTools check)
- Images cached and resized
- Heavy computation in isolates
Testing
- Widget tests for UI components
- Unit tests for business logic
- Integration tests for user flows
- Bloc tests with
blocTest()

How do I install flutter-dev?
Run npx skills add https://github.com/minimax-ai/skills --skill flutter-dev in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/flutter-dev/ (personal) or .claude/skills/flutter-dev/ (project).
Which AI agents can use flutter-dev?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is flutter-dev safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.

pptx-generator
minimax-ai/skills
Generate, edit, and read PowerPoint presentations. Create from scratch with PptxGenJS (cover, TOC, content, section divider, summary slides), edit existing PPTX via XML workflows, or extract text with markitdown. Triggers: PPT, PPTX, PowerPoint, presentation, slide, deck, slides.
minimax-docx
minimax-ai/skills
Professional DOCX document creation, editing, and formatting using OpenXML SDK (.NET). Three pipelines: (A) create new documents from scratch, (B) fill/edit content in existing documents, (C) apply template formatting with XSD validation gate-check. MUST use this skill whenever the user wants to produce, modify, or format a Word document — including when they say "write a report", "draft a proposal", "make a contract", "fill in this form", "reformat to match this template", or any task whose final output is a .docx file. Even if the user doesn't mention "docx" explicitly, if the task implies a printable/formal document, use this skill.
minimax-pdf
minimax-ai/skills
Use this skill when visual quality and design identity matter for a PDF. CREATE (generate from scratch): "make a PDF", "generate a report", "write a proposal", "create a resume", "beautiful PDF", "professional document", "cover page", "polished PDF", "client-ready document". FILL (complete form fields): "fill in the form", "fill out this PDF", "complete the form fields", "write values into PDF", "what fields does this PDF have". REFORMAT (apply design to an existing doc): "reformat this document", "apply our style", "convert this Markdown/text to PDF", "make this doc look good", "re-style this PDF". This skill uses a token-based design system: color, typography, and spacing are derived from the document type and flow through every page. The output is print-ready. Prefer this skill when appearance matters, not just when any PDF output is needed.
