Flutter go_router how to return result to previous page?

Question

I'm trying to open a page and get returned result with go_router package. In Navigation 1.0 I use this:

final result = await Navigator.push(
  context,
  MaterialPageRoute(builder: (context) => const SecondRoute()),
);
// handle result

But I can't seem to do it with go_router. Any solution or explaination?

Solution

This flow is described in the docs here: https://gorouter.dev/user-input

Generally you have to update the data and return some value back as a route with params and the screen itself should manage updates / data manipulation.

I don't want to copy paste their code here, but the answer you are looking for is in the docs page above.

You need to access the returned data from the 2nd page on the 1st page? Is that what you were trying to say ?

I'm asking about go_router package. Not how Navigator.push Navigator.pop work, I know this. go_router do not return Future like Navigation 1.0

I didn't get it that using user input. Can you please add code here to get data back from screen 2 to screen 1 (previous screen) ?

@MaheshPeri19 please follow docs, they are well documented & self-explainable.

Sure. Thanks for the reply.

As I understand, the documentation basically says that there is no way to await a result using the go_router. It suggests you do the data handling in the "user input page" and navigate away when you saved the data without returning to the original page. This means you can't do a simple picker screen (in my case pick a place from a full-screen map). The only way you can do this is to use the plain navigator API and handle everything manually (eg.: navigation guards, route-based providers that are injected by the router, etc.).

Theres an open issue here: github.com/flutter/flutter/issues/99663. It might solve your problem once its done.
