[BUG] Spam pinch zoom in and out V5
What is the bug?
When you spam pinching zoom in and out and at the end i get this error:
The following assertion was thrown while handling a gesture:
'package:latlong2/latlong/LatLng.dart': Failed assertion: line 33 pos 16: 'latitude >= -90 && latitude <= 90': is not true.

Minimum: Allows normal functioning
At the moment i'm using v5, due to issues with v6
Also notice somtimes i could get Infinity to NaN which cause the app freeze
We're unable to provide much support for bugs like this in older versions, but we'll keep it open for now. Thanks for reporting!
I understand, but can it be avoided until i can uppgradera to v6. Also i have no idea if this bug is in v6
Unfortunately it probably can't be avoided, as it's a bug in the internals. Not sure if it's in V6 either, but there is a gesture rewrite on the way at some point soon, so hopefully that should help.
This is an issue with latlong2. it asserts that lat, lon objects are within +-90, +-180. which is causing the crash. potentially there is also still an issue with the gesture system too but #1750 (or a fix upstream) might fix the issue
I would imagine we're not applying the extremity constraints correctly or something, and when a frame is skipped, it doesn't do the check? Or something like that maybe?
