This is a clone of the marquee package that uses a CustomPainter instead
of a ScrollView for better performance.
Many parts of this package (including most parameter names, some assertion
code, some documentation, and most of this README) are copied from marquee. Switching should
be a fairly straightforward process.
⏩ A Flutter widget that scrolls text infinitely. Provides many customizations including durations, curves, and fading, as well as pauses after every round and start delays.
Appreciate the widget? Show some ❤️ and star the repo to support the project.
This is a minimalistic example:
Marquee(
text: 'There once was a boy who told this story about a boy: "',
)And here's a piece of code that makes full use of the marquee's customizability:
Marquee(
text: 'Some sample text that takes some space.',
style: TextStyle(color: Colors.blue, fontWeight: FontWeight.bold),
velocity: 100,
blankSpace: 10,
startPadding: 10,
reverse: true,
bounce: true,
startAfter: const Duration(seconds: 2),
pauseAfterRound: const Duration(seconds: 1),
numberOfRounds: 5,
showFadingOnlyWhenScrolling: false,
fadingEdgeStartFraction: 0.05,
fadingEdgeEndFraction: 0.05,
curve: Curves.easeInOut,
)For more information about the properties, have a look at the API reference.
