Calling a refactored RoundedLoadingButton exceptions with the parent code

[mathems-m]

Hi

I have wanted buttons of a uniform appearance which shall feature animation on presses. So I refactored (made a child from) the RoundedLoadingButton widget.

It is when the child widget is featured within an app and all of the relevant imports are made, that Flutter begins to flag exceptions with the parent code.

Could you advise me on how to achieve the desired result without the exceptions please? The refactored code is attached for your consideration.

With thanks

Mathems
