Search Flutter API docs for any class, widget, method, or enum. Returns description, properties, methods, and constructors.

Search Dart API docs for core library classes. Returns description, properties, methods, and constructors.

Get pub.dev package details including version, score, dependencies, and installation instructions.

Search the curated Flutter widget catalog. Returns widget properties, usage tips, and best practices.

Diagnose common Flutter errors and get solutions with code examples. Paste the error message for diagnosis.

Query Flutter breaking changes by version or keyword. Useful for migration planning.

Dart language feature reference with syntax, examples, and tips. Covers records, patterns, sealed classes, and more.

Generate Flutter/Dart boilerplate code. Supports StatelessWidget, StatefulWidget, BLoC, Riverpod, tests, freezed, and repository patterns.

FIRST STOP when writing advanced Flutter code. Search the verified sample corpus (custom render objects, shaders, slivers, animation physics, isolates, platform channels, go_router, golden tests, performance patterns) by describing what you're building. Returns the best-match sample in full with gotchas.

Get a specific sample from the advanced corpus by id, with complete compilable code and notes.

Browse the advanced sample corpus index, optionally filtered by category.

Opinionated, current best-practice guidance for Flutter projects: architecture, state management choice, project structure, theming, error handling, flavors/CI, package picks. Query by topic or entry id.

Grep the vendored ground-truth source of flutter_reactive_ble and its federation (reactive_ble_platform_interface, reactive_ble_mobile — Dart API, Android Kotlin, iOS/macOS Swift, protobuf codecs), pinned at the exact versions the sample corpus was verified against. Use when the answer lives in the implementation: what a call actually throws, how the native side maps a GATT status, what goes over the method channel.

Read a file or directory from the vendored flutter_reactive_ble federation source. Call with no path for the package tree and version manifest; a directory path lists it; a file path returns numbered source (paged, 500 lines max per call).
