Hi Yashwardhan,

I went through your issue on stackoverflow.

I don't see an issue with the code snippet you've shared.

In the error I see you have a CustomTabView widget. Are you by chance trying routing within tabs?

If that's the case, you will require to define routes for each tab.

If you could provide me an example of your code with some more context, I could help you find where your error is occuring.
