Flutter Navigation pop to index 1

Question

I am recursively adding routes to the navigator. There could be 20 views or more. Pop works as advertised, but I would like to pop to index 1 and remove all push history.

Answer 1

I tried other answers in this post, and somehow they causing the following exception.

To safely refer to a widget's ancestor in its dispose() method, save a reference to the ancestor by calling dependOnInheritedWidgetOfExactType() in the widget's didChangeDependencies() method.

The relevant error-causing widget was
    MaterialApp 
lib/main.dart:72
When the exception was thrown, this was the stack
#0      Element._debugCheckStateIsActiveForAncestorLookup. 
package:flutter/…/widgets/framework.dart:3781
#1      Element._debugCheckStateIsActiveForAncestorLookup 
package:flutter/…/widgets/framework.dart:3795
#2      Element.dependOnInheritedWidgetOfExactType 
package:flutter/…/widgets/framework.dart:3837
#3      Theme.of 
package:flutter/…/material/theme.dart:128
#4      XXxxXX.build. 
package:xxx/widgets/xxx.dart:33
...
