StacPlaceholder class

A Stac model representing Flutter's Placeholder widget.

Draws a simple box to visualize where a widget will be added in the future. Useful during development to indicate unimplemented parts of the UI.

Dart Example:

StacPlaceholder(
  fallbackWidth: 200,
  fallbackHeight: 100,
  strokeWidth: 2,
)

JSON Example:

{
  "type": "placeholder",
  "fallbackWidth": 200,
  "fallbackHeight": 100,
  "strokeWidth": 2
}
