StyleRule.keyframes constructor
Renders a @keyframes css rule.
The @keyframes CSS at-rule controls the intermediate steps in a CSS animation sequence by defining styles for
keyframes (or waypoints) along the animation sequence. This gives more control over the intermediate steps of
the animation sequence than transitions.
Implementation
const factory StyleRule.keyframes({required String name, required Map<String, Styles> styles}) = KeyframesStyleRule;
