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

Navigate Flutter apps across mobile and web with Navigator API or go_router, including deep linking and browser history. \n \n Choose Navigator API for simple apps without deep linking; use go_router for production apps requiring deep links, browser history support, and URL-based navigation across platforms \n Pass data between screens via constructor arguments (Navigator) or URL query parameters (go_router); return data using Future-based pop with typed results \n Configure deep linking through

Flutter development with Riverpod state management, Freezed immutable models, go_router navigation, and mocktail testing. \n \n Riverpod provider ecosystem covers simple values, mutable state, async operations, streams, and parameterized data with family modifiers; AsyncValue pattern handles loading, error, and data states uniformly \n Freezed generates immutable data classes and union types for sealed state modeling; integrates with JSON serialization via json_serializable \n go_router provides

Comprehensive guide for using drift database library in Flutter applications.
