Column Name Mapping

When your application uses custom classes to represent data objects stored in the database, Backendless maps the column names in the database to the fields/properties declared in a custom class. For example, consider the following class:

import 'package:backendless_sdk/backendless_sdk.dart';

@reflector
class Person {
  String name;
  int age;
  String objectId;
}
When an instance of the class is saved in the Backendless database, it creates a table with the following schema:
person-table

As you can see the names of the columns match the names of the properties in the class. However, sometimes that mapping cannot be observed and a property in the class must have a different name or capitalization than the name of the column. In order to override the default mapping, Backendless supports an annotation which allows to map a property to a column. Consider the following example:

import 'package:backendless_sdk/backendless_sdk.dart';

@reflector
class Person {
  String objectId;
  @MapToProperty("name")
  String Name;
  @MapToProperty("age")
  int Age;
}
}

The example demonstrates the mapping of the "Name" and "Age" properties in the client application to the "name" and "age" columns in the database . The mapping is bidirectional, it means it works for both saving objects in and retrieving from the database.
