Record is a dynamic DTO that represents a one-dimensional data structure.

For example

import 'package:nimbus4flutter/nimbus4flutter.dart';

Record record = Record(
  RecordSchema(
    [
      FieldSchema<String>("name"),
      FieldSchema<int>("age")
    ]
  )
);
record["name"] = "hoge";
record["age"] = 20;
