customRouteBuilder's completion result type has broken in the 8.0.3 version

[SergeShkurko]

Now, return types don't work with customRouteBuilder correctly

Because of the last commit c2953fe. Type annotation removed from the function

/// Signature for custom router builder used by
/// [CustomRouteType]
-typedef CustomRouteBuilder = Route<T> Function<T>(
+typedef CustomRouteBuilder<T> = Route<T> Function(
  BuildContext context,
  Widget child,
  AutoRoutePage<T> page,
);

Then any reusable customRouteBuilder implementation will return Route with a dynamic type. We won't return any route with passed by router type. We need to handle generics inside the function. Like earlier

More earlier versions work pretty

@SergeShkurko try specifiying the type when returning your custom Route e.g DialogRoute<String>(....)

I have same issue.

@Milad-Akarie I'm running into the same problem mainly because I have a custom class that extends the CustomRoute class to avoid boilerplate code, so I can't explicitly pass the return type.

I have different CustomRoute classes with different animations that combined in the navigation stack perform different forward/back animations such as iOS modal animations styles.

class MyRoute extends CustomRoute {
  MyRoute({
    required super.page,
    ...
    super.opaque,
  }) : super(customRouteBuilder: <T>(BuildContext context,
    Widget child,
    AutoRoutePage<T> page,
  ) => MyRoutePage<T>(
              builder: (context) => child,
              settings: page,
            ));
}

I solved with this workaround that forces me to specify the return type in the navigation tree declaration too:

class MyRoute<R> extends CustomRoute {
  MyRoute({
    required super.page,
    ...
    super.opaque,
  }) : super(customRouteBuilder: (BuildContext context,
    Widget child,
    AutoRoutePage<T> page,
  ) => MyRoutePage<R>(
              builder: (context) => child,
              settings: page,
            ));
}

We encounter the same issue for 8.0.3.

class DialogAutoRoute extends CustomRoute {
  DialogAutoRoute({
    required super.page,
    super.barrierDismissible,
    super.path,
  }) : super(
          opaque: false,
          transitionsBuilder: TransitionsBuilders.fadeIn,
          durationInMilliseconds: dialogAutoRouteDefaultDuration,
          reverseDurationInMilliseconds: dialogAutoRouteDefaultDuration,
          customRouteBuilder: <T>(context, child, routePage) => DialogRoute(
            context: context,
            builder: (_) => child,
            barrierDismissible: barrierDismissible,
            settings: routePage,
          ),
        );
}

Any plans on fixing this issue?

Still same issues for me when I upgrade auto_route to Ver. 8, with my both custom bottomSheet route and dialog route.
