Column constructor Null safety
- {Key? key,
- MainAxisAlignment mainAxisAlignment = MainAxisAlignment.start,
- MainAxisSize mainAxisSize = MainAxisSize.max,
- CrossAxisAlignment crossAxisAlignment = CrossAxisAlignment.center,
- TextDirection? textDirection,
- VerticalDirection verticalDirection = VerticalDirection.down,
- TextBaseline? textBaseline,
- List<
Widget> children = const <Widget>[]}
Creates a vertical array of children.
The mainAxisAlignment, mainAxisSize, crossAxisAlignment, and verticalDirection arguments must not be null. If crossAxisAlignment is CrossAxisAlignment.baseline, then textBaseline must not be null.
The textDirection argument defaults to the ambient Directionality, if
any. If there is no ambient directionality, and a text direction is going
to be necessary to disambiguate start
or end
values for the
crossAxisAlignment, the textDirection must not be null.
