'Flutter: WidgetApp vs CupertinoApp/MaterialApp for an app that needs to looks the same on each platform

I have just started to learn Flutter and currently using the FlutterApp and retheming certain things so its looks nice and also NON cupertino / material.

My confusion is, should I just use a standard WidgetApp, this is what the "APPS" inherit from.

Or is it safe to use a MaterialApp and just customise it ?

If I use a WidgetApp then I lose some functionality but I am not sure what.

I have a customized Design so the Material / Cupertino design languages are not being used in the design.

Can anyone help ?
