Compass Not Moving - Compass sensor is unreliable, device calibration is needed.

[md-rifatkhan]

I got Compass sensor is unreliable, device calibration is needed.

import 'dart:async';
import 'dart:math';
import 'package:flutter/material.dart';
import 'package:flutter_qiblah/flutter_qiblah.dart';
import 'package:flutter_svg/svg.dart';

class Qibla extends StatelessWidget {
  final _compassSvg = SvgPicture.asset('assets/qibla/compass.svg');
  final _needleSvg = SvgPicture.asset(
    'assets/qibla/needle.svg',
    fit: BoxFit.contain,
    height: 300,
    alignment: Alignment.center,
  );

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: StreamBuilder(
        stream: FlutterQiblah.qiblahStream,
        builder: (_, AsyncSnapshot<QiblahDirection> snapshot) {
          if (snapshot.connectionState == ConnectionState.waiting) {
            return const Center(child: CircularProgressIndicator(),);
          }

          final qiblahDirection = snapshot.data;

          return Stack(
            alignment: Alignment.center,
            children: <Widget>[
              Transform.rotate(
                angle: ((qiblahDirection?.direction ?? 0) * (pi / 180) * -1),
                child: _compassSvg,
              ),
              Transform.rotate(
                angle: ((qiblahDirection?.qiblah ?? 0) * (pi / 180) * -1),
                alignment: Alignment.center,
                child: _needleSvg,
              ),
              Positioned(
                bottom: 8,
                child: Text("${qiblahDirection?.offset.toStringAsFixed(3)}°"),
              )
            ],
          );
        },
      ),
    );
  }
