SpinnerModel class

A spinner widget for showing loading/activity states.

The spinner animates through frames at a configurable rate. It follows the Elm Architecture pattern and can be composed into larger components.

Example

class LoadingModel implements Model {
  final SpinnerModel spinner;
  final String message;

  LoadingModel({SpinnerModel? spinner, this.message = 'Loading...'})
      : spinner = spinner ?? SpinnerModel();

  @override
  Cmd? init() => spinner.tick(); // Start the animation

  @override
  (Model, Cmd?) update(Msg msg) {
    final (newSpinner, cmd) = spinner.update(msg);
    return (
      LoadingModel(spinner: newSpinner, message: message),
      cmd,
    );
  }

  @override
  String view() => '${spinner.view()} $message';
}
