bluetooth_rfcomm_flutter 0.1.0

Flutter plugin that adds the Android native build for bluetooth_rfcomm (Bluetooth Classic RFCOMM serial). Add it to a Flutter app and use the bluetooth_rfcomm API.

bluetooth_rfcomm_flutter

The Flutter plugin for Bluetooth Classic (RFCOMM serial). It adds the Android native build and re-exports the bluetooth_rfcomm API, so there is no separate Dart surface to learn.

Android needs a JVM + Gradle build for its Kotlin/JNI bridge, which can't ship as a Dart-only package — this plugin provides it and bundles the native library into your app. Everything else is handled by the bluetooth_rfcomm core directly: Linux and Windows are pure Dart, and iOS and macOS are compiled by the core's native-assets build hook (for both CLI and Flutter — there is no separate iOS plugin here). Add this plugin to a Flutter app that targets Android; an iOS-only or desktop-only Flutter app can depend on bluetooth_rfcomm directly.

Support

Platform	RFCOMM serial	Manually verified
Android	✅	❌
iOS	⚠️	❌

In the capability column: ✅ supported · ⚠️ partial · ❌ not supported.

Manually verified — whether the author has exercised this backend on real hardware: ⚠️ = yes (works well enough for the author, but not guaranteed to be perfect); ❌ = not yet hardware-verified (implemented, but its effectiveness has not been confirmed by the author).

⚠️ Neither the Android nor the iOS backend has been manually verified on a device yet — treat both as best-effort for now. Of the bluetooth_rfcomm backends, only macOS and Windows (provided by the pure-Dart core, used on desktop) currently carry any manual verification. Every backend will be verified on hardware over time.

This plugin builds only the Android native library. The iOS backend (and the macOS, Linux and Windows backends) all come from the bluetooth_rfcomm core — iOS and macOS via its native-assets build hook, Linux and Windows as pure Dart.

iOS reaches only MFi accessories; a non-MFi device throws BluetoothUnsupportedException.

Install

dependencies:
  bluetooth_rfcomm: ^0.1.0
  bluetooth_rfcomm_flutter: ^0.1.0

Usage

Import bluetooth_rfcomm and use it exactly as in a pure-Dart app:

import 'package:bluetooth_rfcomm/bluetooth_rfcomm.dart';

final bt = BluetoothRfcomm.instance;
final paired = await bt.bondedDevices();
final conn = await bt.connect(paired.first);

The full API, the connection model, platform setup (Android runtime permissions, iOS Info.plist keys and the MFi caveat), logging control, and the test fake are documented in the bluetooth_rfcomm README. A runnable Flutter demo is in example/.
