String stringify(Map<String, dynamic> map)

Implementation

    if (value == null) {
      return 'null';
    } else if (value is num || value is bool) {
      return value.toString();
    } else if (value is DateTime) {
      // Always put quotes around ISO8601 string representation of DateTime
      return '"${value.toLocal().toIso8601String()}"';
    } else if (value is Map) {
      return stringify(Map<String, dynamic>.from(value));
    } else if (value is List) {
      return '[${value.map((v) => encodeValue(v)).join(', ')}]';
    } else if (value is Record) {
      return Json.stringify(value.toJson());
    } else {
      // Strings or any other types, always return quoted
      String str = value.toString().replaceAll('"', r'\"');
      return '"$str"';
    }
  }

  return '{${map.entries.map((e) => '"${e.key}": ${encodeValue(e.value)}').join(', ')}}';
