MDC 101 throwing ROUTE exception

[KinginDev]

I just started the MDC 101 tutorial and after follwing all the installation steps and running: Flutter doctor i am getting this error message. Pls how can i fix this

 I/flutter (29828): The following message was thrown:
I/flutter (29828): Could not navigate to initial route.
I/flutter (29828): The requested route name was: "/login"
I/flutter (29828): The following routes were therefore attempted:
I/flutter (29828):  * /
I/flutter (29828):  * /login
I/flutter (29828): This resulted in the following objects:
I/flutter (29828):  * null
I/flutter (29828):  * MaterialPageRoute<void>("/login", animation: null)
I/flutter (29828): One or more of those objects was null, and therefore the initial route specified will be ignored and
I/flutter (29828): "/" will be used instead.
