ScaleUpWidget class

A widget that scales up its child based on the available height.

The ScaleUpWidget scales up its child widget based on the available height and a maximum height value. It calculates the scale factor based on the available height and applies it to the child widget using a Transform.scale widget. The scaled child widget is then wrapped in a SizedBox to limit its height and width based on the scale factor.

The availableHeight parameter specifies the available height for scaling. The child parameter is the widget to be scaled up. The maxHeight parameter defines the maximum height for the scaled child widget.

Example usage:

ScaleUpWidget(
  availableHeight: 300,
  child: Container(
    color: Colors.blue,
  ),
  maxHeight: 200,
)
