AnimatedAlign class

Animated version of Align which automatically transitions the child's position over a given duration whenever the given alignment changes.

Here's an illustration of what this can look like, using a curve of Curves.fastOutSlowIn.

See also:

  • AnimatedContainer, which can transition more values at once.
  • AnimatedPadding, which can animate the padding instead of the alignment.
  • AnimatedPositioned, which, as a child of a Stack, automatically transitions its child's position over a given duration whenever the given position changes.
