Firebase Auth - signInWithEmail and password throw exception with undocumented code.

[safield]

I am calling FirebaseAuth.signInWithEmail and password.

It is throwing an exception with a code of 'too-many-requests', which is undocumented in the source code comment....

/// Attempts to sign in a user with the given email address and password.
 ///
 /// If successful, it also signs the user in into the app and updates
 /// any [authStateChanges], [idTokenChanges] or [userChanges] stream
 /// listeners.
 ///
 /// **Important**: You must enable Email & Password accounts in the Auth
 /// section of the Firebase console before being able to use them.
 ///
 /// A [FirebaseAuthException] maybe thrown with the following error code:
 /// - **invalid-email**:
 ///  - Thrown if the email address is not valid.
 /// - **user-disabled**:
 ///  - Thrown if the user corresponding to the given email has been disabled.
 /// - **user-not-found**:
 ///  - Thrown if there is no user corresponding to the given email.
 /// - **wrong-password**:
 ///  - Thrown if the password is invalid for the given email, or the account
 ///    corresponding to the email does not have a password set.
Future<UserCredential> signInWithEmailAndPassword({
   required String email,
   required String password,
 }) async {
   return UserCredential._(
     this,
     await _delegate.signInWithEmailAndPassword(email, password),
   );
 }
