I am trying to use a flip_card flutter package to flip items in a list view builder. I want each item flip automatically and with different random time. How can I achieve that.

ListView.builder(
                    scrollDirection: Axis.horizontal,
                    itemCount: length,
                    itemBuilder: (context, index) {
    return FlipCard(
          fill: Fill.fillBack, // Fill the back side of the card to make in the same size as the front.
          direction: FlipDirection.HORIZONTAL, // default
          front: Container(
                child: Text('Front'),
            ),
            back: Container(
                child: Text('Back'),
            ),
        );
