email property
String?
get
email
The email address of the signed in user.
Applications should not key users by email address since a Google account's email address can change. Use id as a key instead.
Important: Do not use this returned email address to communicate the
currently signed in user to your backend server. Instead, send an ID token
which can be securely validated on the server.
GoogleSignInAccount.authentication.idToken
provides such an ID token.
Implementation
String? get email;
