Adiciona visualizações interativas de widgets ao projeto usando o sistema previews.dart. Utilize ao criar novos componentes de UI ou ao atualizar telas existentes para garantir design consistente e testes interativos.
Esta habilidade permite adicionar visualizações interativas de widgets (previews) ao seu projeto Flutter, utilizando o sistema previews.dart. É especialmente útil para desenvolvedores que estão criando novos componentes de UI ou atualizando telas existentes, pois garante consistência de design e permite testes interativos rápidos sem a necessidade de compilar e executar todo o aplicativo. Compatível com ferramentas como Claude Code, Cursor e Codex, a habilidade automatiza a criação de arquivos de preview, gerando código Dart com a estrutura adequada de `@Preview` e `WidgetPreview`. Ela analisa o contexto do projeto e insere os previews no local correto, seguindo as melhores práticas do Flutter para desenvolvimento de interfaces.

Configure your Flutter app to support assistive technologies like Screen Readers
Triggers an accessibility scan through the widget_inspector and automatically adds Semantics widgets or missing labels to the source code.
Adds home screen widgets to a Flutter app for Android and iOS. Use when providing glanceable app information or quick actions on the device home screen.
Configures Flutter Driver for app interaction and converts MCP actions into permanent integration tests. Use when adding integration testing to a project, exploring UI components via MCP, or automating user flows with the integration_test package.
Implement a component-level test using `WidgetTester` to verify UI rendering and user interactions (tapping, scrolling, entering text). Use when validating that a specific widget displays correct data and responds to events as expected.
Implements animated effects, transitions, and motion in a Flutter app. Use when adding visual feedback, shared element transitions, or physics-based animations.
Add animated effects to your Flutter app
Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.
Measure and reduce the size of the Flutter app bundle, APK, or IPA
Architects a Flutter application using the recommended layered approach (UI, Logic, Data). Use when structuring a new project or refactoring for scalability.
Use the Flutter team's recommended app architecture
Builds Flutter forms with validation and user input handling. Use when creating login screens, data entry forms, or any multi-field user input.
Builds Flutter layouts using the constraint system and layout widgets. Use when creating or refining the UI structure of a Flutter application.
Builds Flutter plugins that provide native interop for other apps to use. Use when creating reusable packages that bridge Flutter with platform-specific functionality.
Use `LayoutBuilder`, `MediaQuery`, or `Expanded/Flexible` to create a layout that adapts to different screen sizes. Use when you need the UI to look good on both mobile and tablet/desktop form factors.
Cache data in a Flutter app
Implements caching strategies for Flutter apps to improve performance and offline support. Use when retaining app data locally to reduce network requests or speed up startup.
Execute long-running tasks in a background thread in Flutter
Work with databases in a Flutter app
Embeds native Android, iOS, or macOS views into a Flutter app. Use when integrating complex native components like maps or web views.
ElevenLabs text-to-speech with mac-style say UX.
Oracle CLI second-model review/debug/refactor/design with selected files, dry-run token checks, API or browser engine.
Capture and automate macOS UI with the Peekaboo CLI.
Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".
Build a throwaway prototype to flesh out a design — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
