Cross-platform microphone recording for Dart and Flutter with the goal of no additional system dependencies for users or devs to install. The only build- time requirement beyond Dart/Flutter is Rust, and eventually that will be obviated via precompiled binaries (TODO).
This is a melos monorepo:
| Package | What it is |
|---|---|
packages/microphone_dart |
Pure Dart (no Flutter); works in CLI tools. Reaches native microphone recording over dart:ffi. |
packages/microphone_flutter |
Flutter plugin. Builds the native library automatically (via cargokit) and re-exports the microphone_dart API. |
native/microphone |
Rust crate. |
| Host | Status |
|---|---|
| Android | Working |
| iOS | Working |
| macOS | Working |
| Ubuntu 24.04 | Working |
| Web | Working |
| Windows 11 | Working |
Web tested on macOS in Chrome and Safari, Ubuntu 24.04 in Chrome and Firefox, and Windows 11 in Chrome and Edge.
Driven by melos (config lives in the root
pubspec.yaml). After dart pub get (or flutter pub get):
dart run melos run native:build # build the Rust shared library
dart run melos run analyze # analyze microphone_dart + microphone_flutter
dart run melos run format # check Dart formatting (format:fix to apply)
dart run melos run test # Dart + Flutter tests
dart run melos run native:test # Rust crate tests
