Navigator pop is delayed

[pdefuns]

Always when I call Navigator.pop(context); it takes some time that the current screen is popped.
I guess this is not the default behaviour?

What is "some time" appx? 100ms 1sec 5sec, ...?

Please add the output of flutter doctor -v.

To investigate we would need a minimal runnable reproduction
as a single file so that we can just copy your code into lib/main.dart of a new project and run to reproduce.

Perhaps an animation that does not do anything visible or similar?

[pdefuns]

Sorry, delay means it's not immediately. When I print something on the close action, it's printed immediately. And if I push another route, it's also immediately - not when I pop a screen.

I'll export the minimal parts as soon as I find some time.

not immediately

Still not clear what time range that would fit.

Can you post a minimal reproduction?

Hey did you fix it? i got same problem, but i solved it. here
go to MaterialPageRoute or paste this code inside on onPressed() { // here } or onTap() { // here } Route route = MaterialPageRoute(builder: (context) => Sample()); and press hold ctrl and click the MaterialPageRoute, if mac use cmd, and inside of it search this = transitionDuration = change the milliseconds to 0 and save. restart your project and its done. hope its work to you. reply if its work. thanks

This must be the reason.
It can be solved by overriding method transitionDuration of CupertinoPageRoute or MaterialPageRoute with
Duration get transitionDuration => const Duration(milliseconds: 0);

[besserwisser]

Changing the transitionDuration to 0 is not a solution! You deactivated the transition and this looks not good at all.

By the way, it only ever happened on iOS in my case and in Debug and is not reliably reproducible. On Android it never happened.

Hi @YAPPDEF
Please check this possible solution
If you're still experiencing this issue, please create a new issue and provide necessary details
Thank you

Thank you bro!

[brianschardt]

I am seeing this too. Settings transitionDurration to 0 seconds solves this issue but as @besserwisser said this is not a true solution.

[TahaTesser]

Could everyone who still has this problem please file a new issue with the exact description of what happens, logs, and the output of flutter doctor -v.
All system setups can be slightly different, so it's always better to open new issues and reference related issues.
