On launch I get the red screen with this error:

I cannot reproduce this issues with latest stable Flutter. Is this maybe something caused by newer Flutter?

In the past, I resolved problems similar to this one by passing the AppRouter() to the onGenerateRoute field in the MaterialApp. Could you try this?

Beyond that I am not sure I can do anything. I only use stable branch so I will probably wait until its fixed in the auto_route package.

I’m on beta channel

I commented out that line 37 from auto_route

package:auto_route/src/extended_navigator.dart:37

I’m using beta for web compilation
