flutter pub add flutter_sensor_compass基于插件公开信息、社区数据与项目使用情况整理的选型参考。
flutter_sensor_compass 包提供了一种简单的方法来访问设备的指南针传感器，可实时提供相对于磁北的方向数据（以度为单位）。它使应用程序能够检测设备的方向，非常适合用于导航、增强现实和基于位置的服务。该插件通过利用设备内置的磁力计工作，并专为无缝集成到 Flutter 应用程序而设计。它支持后台更新，并在极少配置的情况下提供准确的读数。开发者可以轻松订阅方向变化并相应地进行响应。

A plugin to get the orientation of the device (in degrees) relative to the magnetic north.
First add the plugin in your project. Copy the following line below dependencies in your pubspec.yaml file.
dependencies:
...
flutter_sensor_compass: ^0.1.1
Then you need to import the dependency.
import 'package:flutter_sensor_compass/flutter_sensor_compass.dart';
You need to add the following key-value pair into your Info.plist file inside the ios/Runner folder in your project.
<key>NSMotionUsageDescription</key>
<string>A reason to get the permission</string>
You can check if the device is capable of using the compass.
bool isAvailable = await Compass().isCompassAvailable();
Then you can register a new listener for the compass updates.
_compassSubscription =
Compass().compassUpdates(interval: Duration(milliseconds: 200)).listen((value) {
setState(() {
_degrees = value;
});
});
Remember to cancel your StreamSubscriptions after you are done with the compass updates.
_compassSubscription.cancel();
