How to determine which provider the user logged in with

Question

I am using multiple Firebase sign in methods in my app (Facebook, Google, Phone, etc). But once the user is logged in, I am unable to determine which provider was used to sign in.

I tried below(very close to the recommended solution. But does not work): _auth.currentUser().providerData[0].providerId

I expect it to return something like "google.com" or "facebook.com" Instead it returns "firebase"

I cant find any other solution where it clearly lets us determine if a google or facebook sign in was used. All solutions in the forum iOS specific or for web. Can't find anything flutter specific. Appreciate any help in advance.

Answer 1

I checked and _auth.currentUser().providerData[0].providerId does provide "google.com" or "facebook.com"

Not sure at what point it showed me "firebase". Will post to this if I figure this out
