Heading keeps resetting to north

[Lah123]

Describe the bug Every time I turn my device the heading changes shortly but then resets to north.

To Reproduce Steps to reproduce the behavior: Just any map with the CurrentLocationMarker.

Expected behavior I do not expect the heading to reset to north.

Smartphone (please complete the following information):

• OS: Andriod 13.0, physical device
• Flutter map location marker version 10.1.0

This is the code snippit I use:

              CurrentLocationLayer(
                  style: LocationMarkerStyle(
                      marker: const DefaultLocationMarker(color: colorPrimary),
                      headingSectorColor: colorPrimary,
                      accuracyCircleColor: colorPrimary.withValues(alpha: 0.3)))

Additional context Here a video, during the recording I turn my phone from left to right. The map is oriented to the north. I'm facing west (ish) with my phone, so it should point down. Every time it janks to north is the bug I'm facing:

Could you check if this issue persists when running the example project (navigation) on your phone? This will help determine if the problem is specific to your implementation or a more general issue.

[Lah123]

Thank you for your response. I checked the example project and it does the same there

Although less, it is still 'creeping' to north. I read on the internet that it can be someting of my phone (oneplus nord 2), but I did not have this issue in earlier versions of this package. Just to be sure I checked another phone (android) with your example project. There the 'creeping' is gone, but it shows the heading 180 degrees in the wrong direction. It shows south when I point to north. This same 180 degrees issue is showing on iOS phones with my own app (I dont have an iOS phone here so I cannot check it with your example app).

As a summary:

My phone (oneplus nord 2): My app and your example app are creeping to north Another android phone: My app and your example app are 180 degrees in the wrong direction iOS: My app 180 degrees in the wrong direction, unable to test your example app as I dont have a iOS phone right now

Does this help you?

[Lah123]

@tlserver , would you need any other information from my side? I can't get this to work unfortunately.

[tlserver]

Thank you for reporting this issue. I am currently unable to reproduce the problem on my device, so I will need some time to investigate the root cause. If anyone else is willing to help, please feel free to join the discussion here or submit a pull request.

This library is flexible and allows you to use any heading provider you prefer. Starting from version 10, the default heading provider was changed from flutter_compass to flutter_rotation_sensor because flutter_compass is no longer actively maintained.

For now, you can try switching to a different heading provider, such as compassx, or revert back to flutter_compass until this issue is resolved.

Here is an example of how you might configure the heading provider (note: this code is untested):

// In initState
// Configure CompassX or FlutterCompass before use (optional)
_headingStream = CompassX /* or FlutterCompass */.events!.map((event) => LocationMarkerHeading(
  heading: degToRadian(event.heading!),
  accuracy: event.accuracy != null ? degToRadian(event.accuracy!).clamp(0.1, 0.4) : 0.3,
));

// Then, in CurrentLocationLayer()
CurrentLocationLayer(
  headingStream: _headingStream,
);

Please let me know if you have any questions or further insights.

I had the same problem. In iOS when starting my app the direction would start at north no matter what direction I was facing. From there it would track my movements but always in the wrong direction. I installed compassx with your code and it works great.

Hopefully you can fix the this bug.

In the end I also used the compassx to make it work. Hopefully you can find the cause as I would love to use your package.
