Flutter Mapbox NullPointerException: Missing ManeuverView ID After Multiple Attempts
I’m using both the flutter_mapbox_navigation: ^0.2.2 and mapbox_maps_flutter: ^0.6.0 packages in my Flutter project, and I’m facing a strange runtime crash that occurs after first attempts to use the navigation feature. The app works perfectly the first times I try it, but on the second attempt, it crashes with the following error:
Error
