This happens because when you do Navigator.of(context), it will start from the widget associated to the context used. And then go upward in the widget tree until it either find a Navigator or there’s no more widget.

So, it throws an Error

Navigator operation requested with a context that does not include a Navigator.

So, how do I fix it ?

First, let’s reproduce this error :

This example creates a button that attempts to go to ‘/’ on click but will instead throw an exception.

Notice here that in the

onPressed: () => Navigator.pushNamed(context, "/"),

we used context passed by to build of MyApp.

The problem is, MyApp is actually a parent of MaterialApp. As it’s the widget who instantiate MaterialApp! Therefore MyApp’s BuildContext doesn’t have a MaterialApp as parent!

To solve this problem, we need to use a different context.

In this situation, the easiest solution is to introduce a new widget as child of MaterialApp. And then use that widget’s context to do the Navigator call.

There are a few ways to achieve this. You can extract home into a custom class :

Or you can use Builder :

That’s All.
