[Bug]: Cannot start navigation

[sonhoang-diqit]

Is there an existing issue for this?

• I have searched the existing issues

Description of the bug

In my app, I have a background location to submit the current position to the server.
But I determined that the Google navigation can not start navigation. I tried to remove my background location process, but the Google navigation works normally.

This bug only happens on iOS. On Android, I use navigation normally.

Flutter version

3.27.0

Package version

0.5.2

@sonhoang-diqit
As your error suggest that the location is unavailable; documentation to the error code is available here: https://developers.google.com/maps/documentation/navigation/ios-sdk/reference/objc/Enums/GMSRouteStatus.html#gmsroutestatuslocationunavailable

Please let us know if the issue is still valid.

@illuminati1911 in IOS below method always returning NavigationRouteStatus.locationUnavailable this status even i have always allow permission and location service is enabled.

final NavigationRouteStatus status = await GoogleMapsNavigator.setDestinations(msg);

this method is giving NavigationRouteStatus.statusOk in simulation mode but not working in real IOS device or simulator
