Change Navigator.pop() animation duration with page_transition

Question

To have an animation while changing screens I am using the page_transition: ^1.1.5

Here is an example:

Navigator.push(context, PageTransition(type: PageTransitionType.rightToLeft, child: HandymanDocumentsOverview(), duration: Duration(milliseconds: 150)));

Yesterday I installed firebase_core: ^0.5.0 and updated all other Firebase dependencies. And somehow it just feels like the animation speed for Navigator.pop(context); is way slower than before and doesn't even match the first animations speed. Does anyone know how to fix that?

Edit here is my flutter doctor -v

Answer 1

UPDATE: Should be no longer an issue with version 1.1.7+3.

Answer 2

Here's one way of specifying the forward and reverse durations:

Navigator.of(context).push(
  PageRouteBuilder(
    transitionDuration: Duration(milliseconds: 800), // Forward Duration
    reverseTransitionDuration: Duration(milliseconds: 800), // Reverse Duration
    pageBuilder: (BuildContext context,
        Animation<double> animation,
        Animation<double> secondaryAnimation) {
      return NewScreen();
    },
    transitionsBuilder: (BuildContext context,
        Animation<double> animation,
        Animation<double> secondaryAnimation,
        Widget child) {
      return FadeTransition(
        opacity: animation,
        child: child,
      );
    },
  ),
);

The package you are using is not yet updated to set the reverseTransitionDuration which was added to flutter recently. You can upvote this issue to bring attention to it.
