When building a component, most of its attributes can be 'null'. The build() method then starts to negotiate the theme in the tree to obtain the most consistent style possible.

Explanation:

When you build a component Button({double? radius}). You have several possibilities:

Pass the "radius" into the constructor, Button(radius: 12).
Set up a theme extension ButtonThemeExtension(radius: 15).
Let wyatt_ui_kit "negotiate" and try to find a suitable style in the flutter theme. If this negotiation phase fails, then the style is simply not applied.

If, for example, you don't use option 1, then the radius will be 15. If you use neither option 1 nor option 2 then the radius will be 4 as this is the official Material Design value.
