[documentation] how to use backbutton dispatcher

[aoatmon]

Hello,
maybe it's just me,
but I cannot find any reference on if / how GoRouter provides a back button dispatcher

[csells]

It does not. Is that something you need it to do? What problem are you trying to solve?

[FabianVarela]

@aoatmon I made this implementation for BackButtonDispatcher and it works for me.

home: Router<dynamic>(
     routerDelegate: _router.routerDelegate,
     backButtonDispatcher: RootBackButtonDispatcher(),
),

thank you! this works like a charm for nested routers

[csells]

interesting. @FabianVarela @aoatmon what are you attempting to accomplish with the BackButtonDispatcher that GoRouter doesn't do by default?

[mrseth01]

@csells I'm confused. You wrote that you need to provide a back button dispatcher. And then, you said Go Router does this by default.

How do I navigate back? I don't see a "goBack" or "pop" method on GoRouter? What is the best way to go back programmatically?

[csells]

Did I say that you needed to provide a BackButtonDispatcher? Can you point out where I said that so I can fix it?

Navigator.maybePop(context) will go back programmatically.

RootBackButtonDispatcher does what I need it to do, thank you both
