alignment property Null safety

The alignment of the child within the parent when the parent is not yet the same size as the child.

The x and y values of the alignment control the horizontal and vertical alignment, respectively. An x value of -1.0 means that the left edge of the child is aligned with the left edge of the parent whereas an x value of 1.0 means that the right edge of the child is aligned with the right edge of the parent. Other values interpolate (and extrapolate) linearly. For example, a value of 0.0 means that the center of the child is aligned with the center of the parent.

Defaults to Alignment.center.
