A material design "raised button".
A raised button consists of a rectangular piece of material that hovers over the interface.
Use raised buttons to add dimension to otherwise mostly flat layouts, e.g. in long busy lists of content, or in wide spaces. Avoid using raised buttons on already-raised content such as dialogs or cards.
If the onPressed callback is not specified or null, then the button will be disabled and by default will appear like a flat button in the disabledColor. If you are trying to change the button's color and it is not having any effect, check that you are passing a non-null onPressed handler.
Requires one of its ancestors to be a Material widget.
