RecordList class

RecordList is a dynamic DTO that represents a two-dimensional data structure.

For example

import 'package:nimbus4flutter/nimbus4flutter.dart';

RecordList list = RecordList(
  RecordSchema(
    [
      FieldSchema<String>("name"),
      FieldSchema<int>("age")
    ]
  )
);
Record record1 = list.createRecord();
record1["name"] = "hoge";
record1["age"] = 20;
list.add(record1);
Record record2 = list.createRecord();
record2["name"] = "fuga";
record2["age"] = 15;
list.add(record2);
