Implementation

SuperrouteException superrouteErrorFrom(int status, Object? body, String? requestId, {Map<String, String> headers = const {}}) {
  final map = body is Map ? body : const {};
  final rawCode = map['error'] ?? map['code'];
  String? code = rawCode is String ? rawCode : (rawCode == null ? null : '$rawCode');
  final message = map['message'];
  if (code == null && message is String && RegExp(r'^[A-Z_]+$').hasMatch(message)) {
    code = message;
  }
  final description = map['error_description'];
  final text = (description is String ? description : null) ??
      (message is List ? message.join(' ') : message is String ? message : null) ??
      (map['title'] is String ? map['title'] as String : null);

  return SuperrouteException(
    status: status,
    code: code,
    message: text,
    body: body,
    requestId: map['request_id'] is String ? map['request_id'] as String : (requestId ?? _lowerCaseHeaders(headers)['x-request-id']),
    errors: _fieldErrors(map['errors']),
    reasons: map['reasons'],
    data: map['data'],
    headers: headers,
