【解决方案】

routes必须要带上参数，否则会报错，如下所示：

final routes = {
  "/":(content,{arguments}) => Tabs(),
  "/form":(content, {arguments}) => FormPage(),
  "/order":(content, {arguments}) => OrderPage(),
  "/product":(content, {arguments}) => ProductPage(),
  "/search":(content,{arguments}) => SearchPage(arguments:arguments),
};
