Flutter AirPods Plugin

pub package pub points

A Library for accessing AirPods data via CMHeadphoneMotionManager. Simplifies retrieval of information about currently connected AirPods. This plugin uses CMHeadphoneMotionManager, and gathering information starts as soon as the user puts the AirPods into the ear.

Supported Devices:

  • Only iOS 14+ supports this functionality.
  • Supported devices: AirPods (3rd Generation), AirPods Pro, AirPods Max, Beats Fit Pro.

Before You Start

  1. Set the iOS Version: Ensure your project’s iOS version is set to at least iOS 14.

  2. Update Info.plist: Add NSMotionUsageDescription in ios/Runner/Info.plist with a reason for using it:

    <key>NSMotionUsageDescription</key>
<string>Get AirPods movement</string>

Usage

To use this plugin, add flutter_airpods as a dependency in your pubspec.yaml file.

Example

Here is a complete example demonstrating how to use the flutter_airpods package:

import 'package:flutter/material.dart';
import 'package:flutter_airpods/flutter_airpods.dart';
import 'package:flutter_airpods/models/device_motion_data.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Flutter Airpods example app'),
        ),
        body: Column(
          crossAxisAlignment: CrossAxisAlignment.center,
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Center(
              child: StreamBuilder<DeviceMotionData>(
                stream: FlutterAirpods.getAirPodsDeviceMotionUpdates,
                builder: (BuildContext context, AsyncSnapshot<DeviceMotionData> snapshot) {
                  if (snapshot.hasData) {
                    return Text("${snapshot.data?.toJson()}");
                  } else {
                    return const Text("Waiting for incoming data...");
                  }
                },
              ),
            ),
          ],
        ),
      ),
    );
  }
}

Expected JSON Data

When data is available from the connected AirPods, you can expect the following JSON structure:

{
    "quaternionY": 0.21538676246259386,
    "quaternionX": -0.47675120121765957,
    "quaternionW": 0.8522420297864675,
    "quaternionZ": -0.0005364311021727928,
    "pitch": -0.9490214392332175,
    "roll": 0.6807802035216475,
    "yaw": 0.3586524456166643,
    "gravityX": 0.3666117787361145,
    "gravityY": 0.8128458857536316,
    "gravityZ": -0.45263373851776123,
    "accelerationX": 0.005457472056150436,
    "accelerationY": 0.01201944425702095,
    "accelerationZ": -0.005634056404232979,
    "rotationRateX": -0.0419556125998497,
    "rotationRateY": -0.01837937720119953,
    "rotationRateZ": 0.011555187404155731,
    "magneticFieldAccuracy": -1,
    "magneticFieldX": 0,
    "magneticFieldY": 0,
    "magneticFieldZ": 0,
    "heading": 0
}

This example demonstrates how to integrate the flutter_airpods plugin to monitor motion data from supported AirPods models on iOS 14+. Make sure to handle permissions properly and test on supported devices.

当然，以下是一个关于如何使用 flutter_airpods 插件在 Flutter 应用中控制耳机的示例代码。这个插件允许你与连接的 AirPods 或其他兼容的蓝牙耳机进行交互，例如控制播放、暂停、下一首、上一首等操作。

首先，你需要在你的 pubspec.yaml 文件中添加 flutter_airpods 依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_airpods: ^0.3.0  # 请检查最新版本号

然后运行 flutter pub get 来获取依赖。

接下来，你可以在你的 Flutter 应用中使用这个插件。以下是一个简单的示例，展示如何控制音频播放：

import 'package:flutter/material.dart';
import 'package:flutter_airpods/flutter_airpods.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  FlutterAirpods? _airpods;
  bool _isConnected = false;

  @override
  void initState() {
    super.initState();
    _initAirpods();
  }

  Future<void> _initAirpods() async {
    _airpods = FlutterAirpods();

    // 监听连接状态变化
    _airpods!.onConnectionStateChanged!.listen((event) {
      setState(() {
        _isConnected = event == FlutterAirpodsConnectionState.connected;
      });
    });

    // 尝试连接（这里假设耳机已经配对过）
    await _airpods!.connect();
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter AirPods Control'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text('AirPods Connected: $_isConnected'),
              SizedBox(height: 20),
              ElevatedButton(
                onPressed: _isConnected ? () => _playPause() : null,
                child: Text('Play/Pause'),
              ),
              SizedBox(height: 10),
              ElevatedButton(
                onPressed: _isConnected ? () => _nextTrack() : null,
                child: Text('Next Track'),
              ),
              SizedBox(height: 10),
              ElevatedButton(
                onPressed: _isConnected ? () => _previousTrack() : null,
                child: Text('Previous Track'),
              ),
            ],
          ),
        ),
      ),
    );
  }

  Future<void> _playPause() async {
    if (_airpods!.isPlaying) {
      await _airpods!.pause();
    } else {
      await _airpods!.play();
    }
  }

  Future<void> _nextTrack() async {
    await _airpods!.nextTrack();
  }

  Future<void> _previousTrack() async {
    await _airpods!.previousTrack();
  }
}

在这个示例中，我们做了以下几件事：

  1. 在 pubspec.yaml 中添加了 flutter_airpods 依赖。
  2. 在 MyApp 组件的 initState 方法中初始化了 FlutterAirpods 实例，并监听了连接状态的变化。
  3. 在 UI 中显示了当前耳机的连接状态，并提供了三个按钮来控制播放/暂停、下一首和上一首。

请注意，这个插件的功能依赖于设备上的蓝牙和耳机设备的支持情况，可能并不是所有设备都能完全兼容。确保你的开发设备和目标设备都支持这些功能。

此外，这个示例代码仅用于演示目的，实际应用中可能需要更多的错误处理和用户交互逻辑。
