Flutter Azimuth Plugin

A Flutter azimuth plugin which provides easy access to azimuth angle, to build awesome compass (Position sensors or if not available the Position sensors on Android and azimuth on iOS).

|

Features

• Get the angle of azimuth;

Example

The code below shows an example on how to acquire the current position of the device, including checking if the location services are enabled and checking / requesting permission to access the position of the device:

import 'package:flutter_azimuth/flutter_azimuth.dart';
import 'package:flutter/cupertino.dart';
import 'dart:async';

import 'package:flutter_azimuth_example/stream.dart';

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

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  int? haveSensor;
  late String sensorType;

  @override
  void initState() {
    super.initState();
    checkDeviceSensors();
    sensorType = '';
  }

  Future<void> checkDeviceSensors() async {
    int? haveSensor;

    try {
      haveSensor = await FlutterAzimuth.checkSensors;

      switch (haveSensor) {
        case 0:
          {
            // statements;
            sensorType = "No sensors for Compass";
          }
          break;

        case 1:
          {
            //statements;
            sensorType = "Accelerometer + Magnetoneter";
          }
          break;

        case 2:
          {
            //statements;
            sensorType = "Gyroscope";
          }
          break;

        default:
          {
            //statements;
            sensorType = "Error!";
          }
          break;
      }
    } on Exception {
      //
    }

    if (!mounted) return;

    setState(() {
      haveSensor = haveSensor;
    });
  }
