Secure HTTP networking and JSON handling for Flutter apps with background parsing support. \n \n Implements CRUD operations (GET, POST, PUT, DELETE) using the http package with safe URL construction via Uri.https() and strict status code validation \n Provides strongly typed JSON serialization and deserialization using Dart 3 pattern matching with factory constructors and toJson() methods \n Offloads large JSON parsing to background isolates via compute() to prevent UI jank on payloads exceeding

Build three content-fetching and learning skills by creating fetch-tweet, fetch-youtube, and content-digest from scratch. \n \n Learn a two-phase workflow (EXPLAIN + EXECUTE in turn 1, QUIZ in turn 2) that enforces hands-on practice before assessment \n Create fetch-tweet to retrieve and translate X/Twitter content via API, then fetch-youtube to extract and correct YouTube captions using yt-dlp and web search \n Build content-digest with Quiz-First learning methodology, which improves retention

Navigate between screens, handle deep linking, and manage data passing in Flutter applications. \n \n Evaluates app requirements to select the optimal routing strategy: imperative Navigator for simple flows, declarative Router / go_router for deep linking and web support, or nested Navigator for independent sub-flows \n Supports data passing between routes via constructor arguments (preferred) or RouteSettings with type-safe argument extraction \n Implements named routes with MaterialApp.routes
