when<T> method

T when<T>({ required T success(KAuthUser user), required T cancelled(), required T failure(KAuthFailure failure), })

성공/실패/취소에 따라 다른 값 반환

result.when(
  success: (user) => navigateToHome(user),
  cancelled: () => showToast('로그인을 취소했습니다'),
  failure: (failure) => showError(failure.message),
);

Implementation

T when<T>({
  required T Function(KAuthUser user) success,
  required T Function() cancelled,
  required T Function(KAuthFailure failure) failure,
}) {
  if (this.success && user != null) {
    return success(user!);
  }
  if (errorCode == ErrorCodes.userCancelled) {
    return cancelled();
  }
  return failure(this.failure);
}
