Can you make example project or something?

Because i new in Flutter and here is my problem...

I import the package
import 'package:progress_button/progress_button.dart';

I don't not where i has to copy this:

val progressButton = ProgressButton(
    child: Text("Login"),
    onPressed: VoidCallback,
    buttonState: ButtonState.normal,
    backgroundColor: Theme.of(context).primaryColor,
    progressColor: Theme.of(context).primaryColor,
);

Is really the word "val" is the correct? not "var"?
And the onPressed event "VoidCallback"...the error debug says: "The argument type 'Type' can't be assigned to the parameter type '() → void'."

Can you help me with that? Thanks!

Sorry for val, it is something left from writing Kotlin.

VoidCallback should be correct. It corresponds to a function with no parameter and void return type.
