Flutter - How do I pop two screens without using named routing?

Use popUntil method of Navigator class.

e.g.

int count = 0;
Navigator.of(context).popUntil((_) => count++ >= 2);

However, I would recommend defining names for your routes and using popUntil as it is designed as per docs.

Let me know if this helped.

You can just pop it two times;

nav = Navigator.of(context);
nav.pop();
nav.pop();
