Stack constructor Null safety

Stack(
  1. {Key? key,
  2. AlignmentGeometry alignment = AlignmentDirectional.topStart,
  3. TextDirection? textDirection,
  4. StackFit fit = StackFit.loose,
  5. Clip clipBehavior = Clip.hardEdge,
  6. List<Widget> children = const <Widget>[]}
)

Creates a stack layout widget.

By default, the non-positioned children of the stack are aligned by their top left corners.

Implementation

Stack({
  super.key,
  this.alignment = AlignmentDirectional.topStart,
  this.textDirection,
  this.fit = StackFit.loose,
  this.clipBehavior = Clip.hardEdge,
  super.children,
}) : assert(clipBehavior != null);
