Beamer not retaining state of previous screen

[kdomingo]

Navigating to an item's details screen and going back makes the list screen rebuild.

Same issue

I noticed the same. It seems state is only kept when the previous screen is part of the location stack.

E.g. going from LocationA -> LocationB

class LocationB extends BeamLocation<BeamState> {
  @override
  List<BeamPage> buildPages(BuildContext context, BeamState state) {
    return [
      // create whatever (back)stack you desire here.
      // this will also keep the current state of this location in memory
      ...LocationA().buildPages(context, state),
      const WidgetB(),
    ];
  }

  @override
  List<Pattern> get pathPatterns => ["/b"];
}

Disclaimer: I just started using beamer 2 days ago. There could be another way I don't know yet ^^;
