Provider variables is reset

[xOldeVx]

Sometimes ref.read(myProvider) variables is reset (I'm using ChangeNotifierProvider), I wasted a lot of time to see what make it reset, but I have no idea. The only thing I've caught so far is that the global provider is recalled, and that reset all the state of the provider class.
In my app I'm calling ref.read(myProvider).getLastVersion() in the initState of the main class for init version variable (double? version) and all the rest time I'm using ref.read(myProvider).someFunction... ref.watch(myProvider).someVariable..

I have no Idea what make my provider dispose and reset all the provider variables.

I'm using the provider in settingsScreen class and in showModalBottomSheet.
