applyActionCode abstract method
Apply (consume) a Firebase out-of-band action code. For an email-
verification oobCode, this flips the auth record's emailVerified to
true. The code is single-use; a second call with the same code returns
AuthServiceActionCodeFailure.invalidCode.
Implementation
Future<Either<AuthServiceActionCodeFailure, Unit>> applyActionCode(
String oobCode,
);
