If I create a new SatefulWidget I can import 3 different files:
Does it matter which import I use? Or is it a problem if I switch between widgets in my app and each widget uses different import?

A widget is either stateful or stateless. If a widget can change—when a user interacts with it, for example—it's stateful. A stateless widget never changes. Icon , IconButton , and Text are examples of stateless widgets.
Stateful widgets are useful when the part of the user interface you are describing can change dynamically, e.g. due to having an internal clock-driven state, or depending on some system state.
To pass data to stateful widget, first of all, create two pages. Now from the first page open the second page and pass the data. Inside the second page, access the variable using the widget. For example widget.
A StatefulWidget class that creates an instance of a State class The StatefulWidget class is, itself, immutable, but the State class persists over the lifetime of the widget We discuss about it more during this tutorial.
Implementing a stateful widget requires at least two classes which are: A StatefulWidget class that creates an instance of a State class The StatefulWidget class is, itself, immutable, but the State class persists over the lifetime of the widget We discuss about it more during this tutorial.
The answer lies in Flutter developer excellent architectural approach which is StateFulWidget, which maintains state that might change during the lifetime of the widget. Implementing a stateful widget requires at least two classes which are: A StatefulWidget class that creates an instance of a State class
Difference between StateFul and Stateless widget, for creation of StateFulWidget, you require atleast two classes, one the actual page and other class holding state of page. Here, we create MainPage class which is inheriting from StateFulWidget
You can use any of them, in both files it points to the same abstract class.
However, for the seek of readability, you should use one which you already have imported in your file.
