Laravel 5.7 email verification error, route [verification.verify] not defined

I am trying to implement email verification in Laravel 5.7. I have implemented MustVerifyEmail on User model.

class User extends Authenticatable implements MustVerifyEmail 
{ 
}

But after registration I got this error Route [verification.verify] not defined.

What I am missing in this? Please guide?
