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:

If the value is mandatory: a hardcoded value in "wyatt_ui_kit" is chosen.
If not, 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.
