Division and const

[ReinBentdal]

Since the StyleClass widget add new style using methods, there is no way of making it a const. That is because changes is made through the methods instead of being defined in the constructor. I dont know the exact performance difference, but it may be significant. Everything would have to be defined in the constructor like:

StyleClass(
  width: 100,
  height: 100,
  backgroundColor: ColorClass.hex('f5f5f5'),
  etc
)

or even

Division(
  child: Widget,
  onTap: () {},
  width: 100,
  elevation: Elevation(10),
  etc
)

Dart that could change help:

• Allow for shorter dot syntax to access enum values dart-lang/language#357
• extension methods

Personally, I'd rather see the new constructor system on styles / gestures separately (not directly on the Division widget) because the separation between styles, gestures and children is what currently makes division cool imho!

Also, I think that the (double) dotted methods could still be cool to use here and there without overdoing so, so maybe they could stay along with the possibility of directly using constructors where needed.
