Persistent context between routes

[JakubWasilczyk]

While working on my app that uses BLoC and GoRouter I came across a problem that basically whenever I push (not go) a new route, the context is being dropped. It might not seem problematic at first, but in case I want to keep my BLoC's already declared on the second route and just build from them, I have to work around it. Don't know if I'm missing something here, or maybe it's a chosen feature, but I would really appreciate if the context could be maintained at least between the parent route and it's children. Code example of my workaround:

Widget build(BuildContext context) {
    return MultiBlocProvider(
      providers: [
        BlocProvider<DeviceControlBloc>(
          lazy: false,
          create: (context) => deviceControlBloc,
        ),
        BlocProvider<BatteryInfoBloc>(
          lazy: false,
          create: (context) => batteryInfoBloc,
        ),
        BlocProvider<ManipoloControlBloc>(
          lazy: false,
          create: (context) => manipoloControlBloc,
        ),
      ],
      child: Builder(
        builder: (context) => IconButton(
          onPressed: () {
            Map<String, dynamic> extra = {
              "device": device,
              "context": context,
            };
            context.push("/device/admin", extra: extra);
          },
          icon: const Icon(Icons.settings),
          ),
        ),
      )

And then in the router builder (it's a child of /device):

          GoRoute(
            name: "deviceAdmin",
            path: 'admin',
            builder: (context, state) {
              if (state.extra is! Map<String, dynamic>) {
                getIt<AppRouter>().router.pop();
              }
              final extra = (state.extra as Map<String, dynamic>);
              DiscoveredDevice device = extra['device'];
              BuildContext extraContext = extra['context'];

              final deviceBloc = extraContext.read<DeviceControlBloc>();
              final batteryBloc = extraContext.read<BatteryInfoBloc>();

              return MultiBlocProvider(
                providers: [
                  BlocProvider.value(
                    value: deviceBloc,
                  ),
                  BlocProvider.value(
                    value: batteryBloc,
                  ),
                ],
                child: DeviceAdminScreen(device: device),
              );
            },
          ),

I don't know enough about bloc to help here but perhaps @jopmiddelkamp does.
