Customize the style of each component from the theme

[goottime]

I don't know if there is such a thing here, but in forui I saw the ability to customize the style of each component directly from the application theme. In addition, there is also the ability to override the style when creating a component.

I understand that this work is very difficult, but I would like to see something like this here. I hope I did not overload you with tasks)

I'm gonna mark this as onhold until the dart macros feature is finally released on the stable channel. Without it, all of the 71 components would create such a huge boilerplate code in the package.

Actually i'm gonna try to use freezed to see if it's possible.

Closing this in favor of #98 and few other more theme data issues
