颤振删除所有路线 [英] Flutter remove all routes

问题描述

我想开发一个注销按钮，该按钮会将我发送到登录路线，并从 Navigator 删除所有其他路线。该文档似乎并未解释如何制作 RoutePredicate 或具有任何removeAll函数。

I want to develop a logout button that will send me to the log in route and remove all other routes from the Navigator. The documentation doesn't seem to explain how to make a RoutePredicate or have any sort of removeAll function.

推荐答案

我能够使用以下代码完成此任务：

I was able to accomplish this with the following code:

Navigator.of(context)
    .pushNamedAndRemoveUntil('/login', (Route<dynamic> route) => false);

这里的秘密是使用RoutePredicate，它总是返回false （Route< dynamic> ; route）=>错误。在这种情况下，它将删除除我推送的新 / login 路由以外的所有路由。

The secret here is using a RoutePredicate that always returns false (Route<dynamic> route) => false. In this situation it removes all of the routes except for the new /login route I pushed.
