Gesture error: LateInitializationError _mapZoomStart and _lastRotation

[c4xp]

Hi, I wanted to migrate to null-safety for flutter_map also but I get theese errors when I move the map (single gesture)
The map just scrolls to mountains of madness ..
In the meanwhile I will keep using 0.12.0

I/flutter (13018): Another exception was thrown: LateInitializationError: Field '_mapZoomStart@750256441' has already been initialized.
I/flutter (13018): Another exception was thrown: LateInitializationError: Field '_lastRotation@750256441' has already been initialized.

I think it's related to the null-safety migration in: lib/src/gestures/gestures.dart
flutter 2.2.1
flutter_map 0.13.0
latlong2 0.8.0
environment: sdk: ">=2.12.0 <3.0.0"
Virtual device - release R - API level 30

I can provide any other info..

I am experiencing the same as well.

Edit: just to point out that I was using issues/829-nullsafety branch until this morning and it was working fine, so it must have been one of the latest changes.

I think it was probably commit 3ea0500, which happened just before merge, so @danielocampo2 is correct.

I removed final from none-final fields, see #923

Version 0.13.1 is released to pub.dev with hotfix #923
