rect property
A more elaborate Neumorphic TextStyle may render large text with
plenty of room on the glyphs themselves to paint a Curvature-inspired
LinearGradient. By default, this property is null
and only a
TextStyle.color is supplied--no foreground Paint is rendered.
Offering a Rect here for deployment within Neu.buildTextStyle as its Neu.neuTextSpec allows Neu.textStyle to paint a gradient over the glyphs as their paint as opposed to a simple flat color.
Implementation
final Rect? rect;
