颤振中 if (routeSettings.isInitialRoute) 的替代方法是什么

Question

既然 isInitialRoute 已从颤振中删除，我还能用什么代替？ （最初的路线是 / ，如果我们可以直接解决）

    Widget build(BuildContext context) {
      return WillPopScope(
        child: Navigator(
          key: navigationKey,
          initialRoute: initialRoute,
          onGenerateRoute: (RouteSettings routeSettings) {
            WidgetBuilder builder = routes[routeSettings.name];
            if (routeSettings.isInitialRoute) {
              return PageRouteBuilder(
                pageBuilder: (context, __, ___) => builder(context),
                settings: routeSettings,
              );
            } else {
              return MaterialPageRoute(
                builder: builder,
                settings: routeSettings,
              );
            }
          },
        ),
        onWillPop: () {
          if(navigationKey.currentState.canPop()) {
            navigationKey.currentState.pop();
            return Future<bool>.value(false);
          }
          return Future<bool>.value(true);
        },
      );
    }

您必须使用settings.name=='/'，因为routeSettings.isInitialRoute 已弃用。参考this
