Aligned class
Align a point of the follower element with a point on the target element Can optionally pass a widthFactor or heightFactor so the follower element gets a size as a factor of the target element. Can optionally pass a backup which will be used if the element is going to be rendered off screen.

const
Properties
- alignToPortal → AxisFlag
-
Whether to use portal instead of target for X and/or Y axis
finalinherited
- backup → EnhancedCompositedTransformAnchor?
-
If the calculated position would render the follower element out of bounds
(for example, a tooltip would go off screen), a backup can be used.
The offset calculations will fall back to the backup.

finalinherited
- follower → Alignment
-
The reference point on the follower element.
finalinherited
- hashCode → int
-
The hash code for this object.

- heightFactor → double?
-
The height to make the follower element as a multiple of the height of the
target element.

- offset → Offset
-
Offset to shift the follower element by after all calculations are made.
finalinherited
- portal → Alignment
-
The reference point on the
Portal, if enabledfinalinherited - runtimeType → Type

- target → Alignment
-
The reference point on the target element, if enabled
finalinherited
- widthFactor → double?
-
The width to make the follower element as a multiple of the width of the
target element.
