StacSnackBar class

Core model for the SnackBar action.

Shows a Flutter SnackBar built from STAC JSON. Use with StacSnackBarParser to render at runtime.

Dart example:

const StacSnackBar(
  content: {"type": "text", "data": {"text": "Saved"}},
  behavior: StacSnackBarBehavior.floating,
);

JSON example:

{
  "actionType": "showSnackBar",
  "content": {"type": "text", "data": {"text": "Saved"}},
  "behavior": "floating"
}
