HTTP CRUD operations, WebSocket real-time communication, authentication, and performance optimization for Flutter apps. \n \n Covers all HTTP methods (GET, POST, PUT, DELETE) with JSON serialization, plus WebSocket connections for real-time data \n Includes authentication patterns (Bearer tokens, Basic Auth, API keys) and comprehensive error handling by status code \n Provides background JSON parsing with isolates to prevent UI blocking on large responses, plus retry logic with exponential backo

MVVM-compliant data layer for Flutter with Repository pattern, stateless Services, and intelligent local caching strategies. \n \n Guides selection of persistence technology (shared_preferences, sqflite, drift, hive_ce, isar_community, or file I/O) based on data type, size, and relational complexity \n Implements Repository as single source of truth, isolating DatabaseService and ApiClient as private stateless dependencies \n Provides complete code examples for domain models, SQLite operations,

Scaffold and implement cross-platform Flutter plugins with native interop for Android, iOS, Windows, and web. \n \n Supports both standard plugins (Method Channels for platform APIs) and FFI plugins (C/C++ native libraries); choose based on whether you need platform-specific SDK access or direct native code binding \n Federated plugin architecture splits API across app-facing, platform interface, and independent platform implementation packages for team-based development \n Includes step-by-step

Comprehensive caching and performance optimization for Flutter apps across multiple data types and platforms. \n \n Provides decision logic to select appropriate caching mechanisms: in-memory, shared_preferences for key-value pairs, SQLite for relational data, file system for large blobs, and image caching for network images \n Includes stream-based offline-first repository pattern that yields cached data first, then fetches and updates from the network \n Covers Android FlutterEngine pre-warmin

Embed native Android, iOS, or macOS views and web content directly into Flutter applications. \n \n Supports two Android composition modes (Hybrid and Texture Layer) with distinct performance and fidelity tradeoffs; iOS and macOS use Hybrid Composition exclusively \n Includes step-by-step workflows for implementing platform views on Android and iOS, with validation and troubleshooting guidance \n Enables embedding Flutter into existing web applications via Full Page or Multi-view (Embedded) mode

HTTP requests and JSON serialization for Flutter REST API integration and data parsing. \n \n Covers three HTTP methods (GET, POST, PUT, DELETE) with proper status code validation, HTTPS enforcement, and safe URI construction using Uri.https() . \n Offers two serialization strategies: manual fromJson / toJson for simple models, and code generation with json_serializable for complex nested structures. \n Includes background parsing with compute() to prevent UI jank when processing large JSON payl

Provides cross-platform mobile development expertise specializing in Flutter 3+, Dart programming, and Riverpod state management. Builds high-fidelity applications for Mobile, Web, and Desktop with advanced rendering optimization (Impeller), custom render objects, and native integrations via FFI and Method Channels.

This skill outlines the process of adding flutter_driver support to a Flutter application, launching it via the Dart MCP server, controlling it (tapping, finding widgets), and capturing screenshots (handling Web/Desktop specific constraints).

Complete guide for internationalizing Flutter apps with gen-l10n, intl package, and custom approaches. \n \n Covers three setup paths: gen-l10n (recommended, code-generated from ARB files), intl package (manual, code-based), and custom Map-based localizations for maximum flexibility \n Supports message types including simple strings, placeholders with parameters, plurals based on count, and select messages based on string values \n Includes automatic number and date formatting with locale-aware
