factory FirebaseServiceAccountCredentials.fromJson(
  final Map<String, dynamic> json,

  final projectId = json['project_id'] as String?;
  if (projectId == null || projectId.isEmpty) {
    throw const FormatException('Missing or empty "project_id"');
  }

  final clientEmail = json['client_email'] as String?;

  return FirebaseServiceAccountCredentials(
    projectId: projectId,
    clientEmail: clientEmail,
