iPhone Crash

Where is the stacktrace?

[LocaTrackGitHub]

What stacktraces this is a tester reporting this not on my local...not sure what you mean with that? There is no logs and no errors just a guy driving and the background sometimes kicking in sometimes not...

[christocracy]

Without a stacktrace specifically referencing this plugin, it's impossible to say that your crash is due to the plugin or a bug in your own code.

People often use Crashalytics, like the guy in that other issue you posted in.

[LocaTrackGitHub]

Also it tracks lines like this....which to me seems odd and perhaps delayed entries causing it... I will check out crashalytics in tne mean time... Any idea what is causing the lines?

[christocracy]

See api docs Config.distanceFilter to learn about "distanceFilter elasticity"

[LocaTrackGitHub]

Thank you will look into that, this project dont use firebase, seems like crashalytics is based on a firebase project, is there any other flutter crash reporting tool I can use to get you the stack trace?

[heshesh2010]

here is log i think may help u i have same issue :

Metal: MTLReleaseAssertionFailure + 220

[christocracy]

@heshesh2010 your posted stack-trace has nothing to do with this plugin. When you have an iOS stack-trace that references this plugin, you will see symbols referencing TSLocationManager, or other symbols beginning with the prefix TS (for Transistor Software).

[LocaTrackGitHub]

I hope this could somehow help one is a screenshot of how an app I paid for tracks me and the other one where I seem to get preiodic background updates. Both apps were closed whilst driving so I assume its something to do with the background tracking. I am hoping its something implemented wrong or a small adustment that can fix this.

[christocracy]

Why don't you install the /example in this repo and compare that?
