浮动导航中未定义的名称"context" [英] Undefined name 'context' in flutter navigation

问题描述

我想导航到一页，然后使用下面的代码

I want to navigate into one page to another an I used following code to that

创建路线

final routes = <String,WidgetBuilder> {
   DashboardIesl.tag : (context)=>DashboardIesl()
};

导航到按钮单击

onPressed: () {
  Navigator.push(context, new MaterialPageRoute(
    builder: (context) => new DashboardIesl()
  ));
},

它给出如下错误消息

未定义名称上下文".

Undefined name 'context'.

推荐答案

请向我显示更多代码，上下文仅在全状态小部件中可用，

please show me more code,context is only available in statefull widgets,

onPressed: () {  Navigator.push(
context,
MaterialPageRoute(builder: (context) => DashboardIesl()),  );}
