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)}°"),
              )
            ],
          );
        },
      ),
    );
  }
}

and Text("${qiblahDirection?.offset.toStringAsFixed(3)}°"), value is null

Tried in two device

Same Same , what is the solution ??

Same Same , what is the solution ??

It seems that location is still required when senor is available,

Same Same , what is the solution ??

It seems that location is still required when senor is available,

the location is enabled in app

[medyas]

@md-rifatkhan @Obada-Maplit the location is required for the plugin to function. please check the example project

@medyas how are u medyas , i enabled the location in app , but this message still appear on put app near laptop or Magnetfelt that log error in cmd , this error Compass Not Moving - Compass sensor is unreliable, device calibration is needed.

i need only way to recive this message in dart , how to catch it , i need to show warning to user that should app far away from any device .

pls help

[medyas]

@Obada2020 the message is printed in native android by the flutter_compass plugin and currently not able to detect this in the qiblah plugin

Here are the steps to handle this issue effectively:

1. Calibrate the Device's Compass
   Perform a figure-eight motion with your device:
   Hold your device flat and move it in a figure-eight pattern in the air.
   Repeat this several times until the sensor is recalibrated.
2. Ensure a Clean Environment
   Move away from magnetic or metallic objects that may interfere with the compass sensor (e.g., computers, speakers, or other electronics).
   Test the app outdoors for better calibration and less interference.
3. Check for Magnetic Interference
   Use a magnetic field detector app to check for interference around your current location.
   Relocate to an area with less interference if needed.
