expand static method
Creates box constraints that expand to fill another box constraints.
If cross
or main
is given, the constraints will require exactly the
given value in the given dimension.SliverConstraintsUtil
Implementation
static BoxConstraints expand(
Axis axis, {
double? cross,
double? main,
}) {
return axis == Axis.vertical
? BoxConstraints.expand(width: cross, height: main)
: BoxConstraints.expand(width: main, height: cross);
}
