RenderSizedOverflowBox constructor Null safety

RenderSizedOverflowBox(
  1. {RenderBox? child,
  2. required Size requestedSize,
  3. AlignmentGeometry alignment = Alignment.center,
  4. TextDirection? textDirection}
)

Creates a render box of a given size that lets its child overflow.

The requestedSize and alignment arguments must not be null.

The textDirection argument must not be null if the alignment is direction-sensitive.

Implementation

RenderSizedOverflowBox({
  super.child,
  required Size requestedSize,
  super.alignment,
  super.textDirection,
}) : assert(requestedSize != null),
     _requestedSize = requestedSize;
