durationIndicator method

Widget durationIndicator({ required Duration duration, double height = 3.0, Color? color, Color? backgroundColor, BorderRadius? borderRadius, DurationIndicatorDirection direction = DurationIndicatorDirection.leftToRight, })

Creates a duration indicator widget for use in custom snackbar builders

This provides a convenient way to add a progress bar to custom snackbars when using handleDurationTimerManually: true. The indicator shows the remaining time before the snackbar auto-dismisses.

Example usage with a custom builder:

Modal.showSnackbar(
  handleDurationTimerManually: true,
  duration: const Duration(seconds: 4),
  builder: ([_]) => Column(
    mainAxisSize: MainAxisSize.min,
    children: [
      // Your custom content here
      Container(
        padding: const EdgeInsets.all(16),
        child: Text('Custom snackbar'),
      ),
      // Add the duration indicator at the bottom (or anywhere you want)
      Modal.durationIndicator(
        duration: const Duration(seconds: 4),
        color: Colors.blue,
      ),
    ],
  ),
);

Parameters:

• duration: The total duration of the snackbar (required)
• height: Height of the progress bar (default: 3.0)
• color: Color of the progress bar (default: amber)
• backgroundColor: Background track color (default: color with 30% opacity)
• borderRadius: Border radius for the indicator
• direction: Direction of progress animation (leftToRight or rightToLeft)

Implementation

Widget durationIndicator({
  required Duration duration,
  double height = 3.0,
  Color? color,
  Color? backgroundColor,
  BorderRadius? borderRadius,
  DurationIndicatorDirection direction =
      DurationIndicatorDirection.leftToRight,
}) {
  final effectiveColor = color ?? Colors.amber;
  return SnackbarDurationIndicator(
    duration: duration,
    height: height,
    color: effectiveColor,
    backgroundColor: backgroundColor ?? effectiveColor.withValues(alpha: 0.3),
    borderRadius: borderRadius,
    direction: direction,
  );
}
