flutter▌

Automated macOS Flutter development environment setup with dependency validation and diagnostic fixes. \n \n Verifies Flutter installation, Xcode availability, and CocoaPods presence; stops with clear instructions if any prerequisite is missing \n Guides users through Xcode command-line tool configuration and license acceptance with required sudo commands \n Runs iterative flutter doctor validation loops to identify and resolve remaining toolchain issues until the Xcode section passes completely

Automated macOS environment configuration for Flutter development with Xcode and CocoaPods setup. \n \n Guides installation and linking of Xcode command-line tools, acceptance of developer licenses, and CocoaPods dependency management \n Includes validation workflow using flutter doctor and flutter devices to confirm proper environment setup and macOS desktop recognition \n Provides troubleshooting steps for common issues including missing command-line tools, CocoaPods path problems, and desktop

This skill enforces BLoC state management, strict layer separation, and mandatory use of design system constants for all Flutter development in this codebase.

Offload CPU-intensive tasks to background isolates while keeping Flutter UIs responsive. \n \n Provides three concurrency patterns: async / await for I/O-bound work, Isolate.run() for one-off heavy computations, and Isolate.spawn() with message passing for persistent background workers \n Includes a decision matrix to choose between async operations and isolates based on task type (I/O vs. CPU-bound) and execution frequency \n Covers three complete workflows with step-by-step task checklists: st

Implements stateful form validation in Flutter using Form, TextFormField, and GlobalKey<FormState>. Manages validation state efficiently without unnecessary key regeneration and handles user input validation workflows. Assumes a pre-existing Flutter environment with Material Design dependencies available.

Comprehensive guide for implementing animations in Flutter with decision trees and patterns for every animation type. \n \n Covers five animation approaches: implicit animations (AnimatedContainer, AnimatedOpacity, TweenAnimationBuilder), explicit animations (AnimationController, Tween, AnimatedWidget/AnimatedBuilder), hero animations (shared element transitions), staggered animations (sequential/overlapping with Interval timing), and physics-based animations (spring, gravity, fling) \n Includes

Adaptive Flutter layouts that respond to screen size, platform, and input device across mobile, tablet, desktop, and web. \n \n Three-step workflow: abstract common widgets, measure available space with MediaQuery or LayoutBuilder, and branch UI based on width breakpoints (compact <600, medium 600–840, expanded ≥840) \n Covers layout fundamentals including Flutter's constraint system, common patterns (Row, Column, Expanded, Container), and responsive grid/navigation examples \n Best practic

Comprehensive testing framework for Flutter apps across unit, widget, and integration test layers. \n \n Covers three test categories: unit tests for isolated logic, widget tests for UI components, and integration tests for end-to-end flows on real devices or emulators \n Provides architectural testing patterns for ViewModels, Repositories, Services, and Views, with emphasis on Fake implementations over mocks for cleaner test design \n Includes plugin testing guidelines combining Dart tests with

Generates unit, widget, integration, and plugin tests for Flutter applications with architectural awareness. \n \n Analyzes target code to determine appropriate test type (unit for logic, widget for UI, integration for end-to-end, plugin for native code) \n Provides decision tree and step-by-step implementation patterns for each test category, including fake/mock setup and assertion strategies \n Includes ready-to-use code templates for ViewModels, Repositories, widgets, and full app flows with
