switchOutCurve property
The animation curve to use when transitioning a previous child out.
This curve is applied to the child when the child is faded in (or when
the widget is created, for the first child). Changing switchOutCurve
will not affect the curves of already-visible widgets, it only affects the
curves of future children.
If child is changed while the current child is in the middle of fading
in, switchInCurve will be run in reverse from that point instead of
jumping to the corresponding point on switchOutCurve.
