Current problem

On login account-exists-with-different-credential error might happen, in this case we need to know user email that signInWithCredential method throws in FirebaseAuthUserCollisionException exception, so we can use it with fetchSignInMethodsForEmail method as mentioned in this issue: #592

Preferred solution

signInWithCredential will pass email property to Capacitor js scope on FirebaseAuthUserCollisionException exception
