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;
});
}
@override
Widget build(BuildContext context) {
return CupertinoApp(

return Column(
children: [

child: const CompassForeground(),
