Flutter android/web app requesting Google Calendar scope, and Google Cloud verified, but still shows unverified when sign in

[Jimmy Li]

Hi all,

I have a Flutter web and android app using google calendar api, create/edit/delete a calendar for the app's own use. I use googleapis package, and chose "calendarScope" to access google calendar. I then chose "www.googleapis.com/auth/calendar.app.created" in my Google Cloud project. I also got the app verified. But, I still see the alert screen saying that my app is "unverified" when I choose a google account to signin in the app. Is there anything I missed, or wrong?

Thanks.
