Tint class

A widget that applies a color tint over its child.

The tint color is applied as a foreground color overlay on all cells rendered by the child. An opacity of 1.0 fully replaces the foreground with the tint color, while 0.0 has no effect.

In a terminal context, true alpha compositing is not possible, so the tint blends each rendered cell's foreground/background colors toward color.

Tint(
  color: Colors.red,
  opacity: 1.0,
  child: Text('This text appears red'),
)
