Usage

The Marquee repeats its child over and over and scrolls it automatically.

Marquee(
  child: Text('There once was a boy who told this story about a boy: "'),
)

scrollAxis

While normally, the Marquee scrolls horizontally, by setting the scrollAxis property to either Axis.horizontal or Axis.vertical, you can specify the direction in which the Marquee scrolls.

Marquee(
  scrollAxis: Axis.vertical,
  child: Text("Look what's below this:"),
)

blankSpace

If you want to have some space between the children, there's a blankSpace property you can set:

Marquee(
  blankSpace: 300.0,
  child: Text('Wait for it...'),
)

velocity

You can also customize the velocity the Marquee scrolls with. Just set the velocity parameter to any velocity in pixels per second.

Marquee(
  velocity: 1000.0,
  child: Text('Gotta go faaaaaast...'),
)
