how to use polymorphism with provider in flutter - flutter

Question

I try to use Polymorphism with the Provider package in Dart/Flutter, but I'm not sure if it is possible or not and if I have made a mistake.
I have two provider class "Provider1" and "Provider2" which extend an abstract class "AbstactProvider", I have a widget "WidgetProvider1Or2"
which need to interact with Provider1 Or Provider2 but flutter throw me a "ProviderNotFoundException".
thanks for yours help!
