Native crash in Flutter 3

[tonnyavery]

After upgrading to Flutter 3, Mapbox flutter plugin is crashing with a native null pointer exception. Logs are attached.

As nothing was changes in Mapbox SDK integration or native libraries, I have opened a request for investigation help in Flutter repo: flutter/flutter#107297

The crash was there in 3.1.0-0.0.pre.1542, but I couldn't reproduce it on 3.1.0-0.0.pre.1650.
I am still on vacation and don't have good internet, so everybody is welcome to check if crash is still there or we are safe with Flutter 3 migration.

[dawid-niedzwiecki]

I experience the same issue every time I open a screen in my app which has a MapboxMap on it, but then pop the screen from the stack before the MapboxMap has the opportunity to fully load into view.

[tonnyavery]

@dawid-niedzwiecki If you have any insights, please add them to flutter/flutter#107297 so Flutter team could help with investigation

[tonnyavery]

I have made a PR with a potential fix for this crash.
Please test the PR branch against your usecase to confirm that it's working.

[Djcharles26]

News? Im having this issue when reloading too fast the map and in random occasions

[tonnyavery]

@Djcharles26 The fix depends on flutter/flutter#107297
if you have any useful input, be sure to add it there so that Flutter team could faster find a solution

Still seems to cause crash on 3.3.0 stable, though UX is finally fixed. Left StackTrace for them

[serraojoao]

Upgraded to 3.3.0 I did not have layout issues, but the map still crashes the app. If i turn off myLocationEnabled it seems to work ok.

I can confirm that removing the three lines I had for myLocation does not cause the crash.

@cfsbhawkins and @serraojoao feel free to create a new issue with the error you are getting - if the error is different

@felix-ht Its the same null ref crash that this ticket is talking about, it seems that the "fix" is to not use myLocationEnabled options and the map will not crash.

[serraojoao]

It is the same issue

do you have any workaround to have a marker with the current location? I think doing a custom marker as per the custom_marker.dart example for the current location could help but still would not be so nice as the default locationEnabled
