Flutter Material UI Alignment Enum
Alignment uses visual coordinates, which means increasing x moves the point from left to right. To support layouts with a right-to-left TextDirection, consider using AlignmentDirectional, in which the direction the point moves when increasing the horizontal value depends on the TextDirection.
Alignment.bottomCenter: The center point along the bottom edge.
Alignment.bottomLeft: The bottom left corner.
Alignment.bottomRight: The bottom right corner.
Alignment.center: The center point, both horizontally and vertically.
Alignment.centerLeft: The center point along the left edge.
Alignment.centerRight: The center point along the right edge.
Alignment.topCenter: The center point along the top edge.
Alignment.topLeft: The top left corner.
Alignment.topRight: The top right corner.
