[FEATURE] Remove FlutterLogin scroll when keyboard is active.

[surister]

Right now when the keyboard is active, we can scroll up the whole FlutterLogin :

This is because the FlutterLogin widget has a SingleChildScrollView:

This is used mainly to fix the widget resize that happens when the keyboard is active:

but if in the Scaffold we set resizeToAvoidBottomInset property to false.

We avoid the shrink and the scroll which is unpleasant.

What do you guys think? Is there any use case where the user might need the scroll? Should we perhaps make the scroll an option?

@juliansteenbakker Good one I think.
