Implementation

Map<String, dynamic> toJSON() {
  final Map<String, dynamic> result = {
    'id': id,

  // Add optional fields only if they are not null
  if (name != null) result['name'] = name;
  if (phone != null) result['phone'] = phone;
  if (email != null) result['email'] = email;
  if (userCreatedAt != null) result['user_created_at'] = userCreatedAt;
  if (isFirstTimeUser != null) result['is_first_time_user'] = isFirstTimeUser;
  if (mixpanelDistinctId != null) result['mixpanel_distinct_id'] = mixpanelDistinctId;
  if (amplitudeDeviceId != null) result['amplitude_device_id'] = amplitudeDeviceId;
  if (posthogDistinctId != null) result['posthog_distinct_id'] = posthogDistinctId;
