A widget that makes underlying Text.rich or RichText animate like a typewriter.
I was creating a visual novel engine, so I needed a convenient way to animate RichTexts (with styles and WidgetSpans). Actually there are some packages which do the thing, but they do not work with existent RichTexts and/or do not support WidgetSpans.
In addition, it's also a kind of proof of concept in terms of interaction with the element tree.
RichTypewriter(
child: const Text.rich(TextSpan(text: "some text", children: [
WidgetSpan(
child: FlutterLogo(
size: 100,
))
])));
