Allow using "maintainState" in ChildRoute definition

[trevhud]

Project Name
flutter_modular

Is your feature request related to a problem? Please describe.
maintainState is a property of MaterialPageRoute. I use this for my project and would like to use it for named routes in Flutter Modular as well. The problem is that state is always maintained in the navigation stack.

Describe the solution you'd like
Support for maintainState

Describe alternatives you've considered
I've tried just using push with the MaterialPageRoute, but then it doesn't get added to the stack as a named route so popUntil won't work for example.

Additional context

Thanks for your help. Looking for any way to use maintainStatein in named routes.

I added maintainState: true by default. See if it works with this new commit.

@jacobaraujo7 Will this allow me to declare a ChildRoute with maintainState: false?

@jacobaraujo7 Will this allow me to declare a ChildRoute with maintainState: false?

Enabled as default

I guess that's a yes? Thank you for adding this

How do I get to this setting? I see in modular_router_delegate.dart it will throw a Unimplemented exception.
I'm using 4.2.0 and see it was added in 4.1.2, also this thread should have been correctly marked and closed if the feature was correctly added/merged so I take it it was not properly implemented?

Hi @jacobaraujo7, I've taken a look at the latest version and I'm still not seeing how to declare maintainState: false for a ChildRoute. That was my original intention but I'm not sure how to achieve that with Flutter Modular. Could you weigh in please?

@jacobaraujo7 Something must be lost in translation here. I still see no way of overriding the maintainState:true and instead defining a route with maintainState: false. Seems like it would be relatively easy to add right?

[jacobaraujo7]

yes.
I will add this in new version

The work that was done here did not actually allow the intended behavior of maintainState:false. d3be93d#commitcomment-71666653
