EnsureVisible typedef
EnsureVisible =
Future<bool> Function(String id, {Curve curve, Duration duration, Curve jumpCurve, Duration jumpDuration})
A callback to scroll the anchor identified by id
into the viewport.
By default, an internal impl is given to WidgetFactory.onTapAnchor
when an anchor is tapped to handle the scrolling.
A wf subclass can use this to change the curve
, the animation duration
or even request scrolling to a different anchor.
The future is resolved after scrolling is completed.
It will be true
if scrolling succeed or false
otherwise.
