canTransitionTo method
- TransitionRoute nextRoute
Returns true if this route supports a transition animation that runs
when nextRoute
is pushed on top of it or when nextRoute
is popped
off of it.
Subclasses can override this method to restrict the set of routes they need to coordinate transitions with.
If true, and nextRoute.canTransitionFrom()
is true, then the
ModalRoute.buildTransitions secondaryAnimation
will run from 0.0 - 1.0
when nextRoute
is pushed on top of this one. Similarly, if
the nextRoute
is popped off of this route, the
secondaryAnimation
will run from 1.0 - 0.0.
If false, this route's ModalRoute.buildTransitions secondaryAnimation
parameter
value will be kAlwaysDismissedAnimation. In other words, this route
will not animate when nextRoute
is pushed on top of it or when
nextRoute
is popped off of it.
Returns true by default.
See also:
- canTransitionFrom, which must be true for
nextRoute
for the ModalRoute.buildTransitionssecondaryAnimation
to run.
Implementation
@override
bool canTransitionTo(TransitionRoute<dynamic> nextRoute) => nextRoute is PageRoute;
