positionedFill method
Stretches this widget between a Stack's edges.
Offsets default to zero. Null offsets release that edge's constraint. The stack needs a size from its parent or non-positioned children. The same parent-data rules as positioned apply.
Implementation
Positioned positionedFill({
Key? key,
double? left = 0,
double? top = 0,
double? right = 0,
double? bottom = 0,
}) =>
Positioned.fill(
key: key,
left: left,
top: top,
right: right,
bottom: bottom,
child: this,
);
