Deck class

Displays stacked child widgets (typically cards), so the only headers are visible initially. Each item in a Deck can be expanded.

List of DeckItem objects, provided in the items parameter, defines the content of child widgets in their collapsed and expanded states.

The widget height is adjusted to fit all children in respect their expanded state. The size is limited by mainAxisSize, which defaults to half of the device screen height.

Deck item size is defined by collapsedSize and expandedSize parameters. When they are not set, an item in the collapsed state takes 48p, and its expanded size is calculated by number of items and total Deck size.
