AlignmentGeometry alignment

How to align the non-positioned or partially-positioned children in the stack.

The non-positioned children are placed relative to each other such that the points determined by alignment are co-located. For example, if the alignment is Alignment.topLeft, then the top left corner of each non-positioned child will be located at the same global coordinate.

Partially-positioned children, those that do not specify an alignment in a particular axis (e.g. that have neither top nor bottom set), use the alignment to determine how they should be positioned in that under-specified axis.

If this is set to an AlignmentDirectional object, then textDirection must not be null.


AlignmentGeometry get alignment => _alignment;
void alignment=(AlignmentGeometry value)


set alignment(AlignmentGeometry value) {
  if (_alignment == value) {
  _alignment = value;
