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 blending is not possible, so the tint works by replacing the foreground color of each cell when opacity is above 0.5, or leaving it unchanged when below 0.5.

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