As far as I can see, provid

    I am explaining just one limitation which I practically found, there may be others too.

    After searching many tutorials and topics on Get_it that why people use Get_it() even we have dependency injection in the provider, I was unable to understand the difference in terms of DI. Then I stuck in a Scenario and find the answer to your question that "what are the limitations".

    Are there any more differences and limitations between them?.

    Scenario:

    I had Nested widgets, Widget A has Widget B and Widget B has Widget C, I was using the provider and was accessing values in each widget whenever value changed. It was great, Then I make a new widget D which was a separate widget, it was not inside the widget A hierarchy. But when I try to access the same value in Widget D it was not changing. Because widget D is not in the tree of Widget A. Now here comes the limitation of dependency injection of the provider.

    Conclusion

    You will use Get_it to access values out of the tree widget. But you can't access the updated value using provider

    Note

    you need to wrap the app with the provider to access all dependencies.
