问题 I have coded a match making system and this system works like that --> when a create operation came to firestore it matches with an older record and the cloud function deletes both of them. But i wonder that when 2 new records are created, is there any chance for matching these 2 with the same old record because the deletion process takes some time?

问题 I did some research and experiments on integrating LINE login with Firebase Auth using Flutter. I have some questions: Looks like in Firebase Auth, there are AuthProvider , and in Flutter source code, I also found an OAuthProvider . There you can create Credential to include your idToken and access token. But I don't know how to specify the providerId in that Credential . I guess it is not possible, because Firebase hasn't integrate LINE login. The client side api: logInWithCredential can
