Flutter-显示抽屉按钮，而不是后退按钮 [英] Flutter - Drawer button shown instead of back button

问题描述

作为第一个项目，我正在迅速创建购物车。购物车的链接在Appbar内部。

I am creating a shopping cart in flutter as my first project. The link to the Cart is inside Appbar.

当我导航到购物车时，没有显示应用栏左上方的后退按钮，而是显示了抽屉按钮。

When I navigate to the Cart the back button on the top left of the Appbar is not showing, instead the drawer button is shown.

对于我浏览的其他页面（例如产品页面），则显示后退按钮。

For other pages that I navigate say, a product page, the back button is shown.

可能是问题所在，请提出建议。

What could be the issue, please suggest.

推荐答案

我逐行比较购物车和购物车。dart有此违规行

I compare line by line and the cart.dart have this offending line

抽屉：appDrawer

drawer: appDrawer

似乎覆盖了后退按钮。
