How to call dispose method in third screen.

[anup-geeky]

@BilalShahid13 This library is superb. It solved my major design problem.
But give me solution of below scenario.
Let suppose in Home tab, I am in third screen and if I click search tab or any other tab then how to call dispose method in third screen. I want to close some connection in third screen.

How can I do that?

And also if I am on Home tab, go to second screen then how to come first screen on click of same
Home tab.

Thanks in advance.

The possible solution of the first problem will be to pass the PersistentTabController declared with the nav bar to the 3rd screen. You can do that by passing through arguments to successive screens or something like a provider. Then on the 3rd screen, add a listener to the controller in the initState or somewhere else. When index change is detected, call the dispose method.

Now for the second one, it is currently only possible by using a custom widget and defining your own tap function for an item. But this is an interesting feature which I'm hoping to add in a future update. Thanks for the suggestion!

The feature for popping to first screen on tapping an already selected tab is added in version 1.5.1. Please check it out.

Keep in mind that I'm using Flutter's default Navigator.canPop(context) to decided whether I can pop a screen or not. This does not work sometimes and I'm actively looking for the answer.
