ManagedObject<T> class Null safety

An object that represents a database row.

This class must be subclassed. A subclass is declared for each table in a database. These subclasses create the data model of an application.

A managed object is declared in two parts, the subclass and its table definition.

    class User extends ManagedObject<_User> implements _User {
      String name;
    }
    class _User {
      @primaryKey
      int id;

      @Column(indexed: true)
      String email;
    }

Table definitions are plain Dart objects that represent a database table. Each property is a column in the database.

A subclass of this type must implement its table definition and use it as the type argument of ManagedObject. Properties and methods declared in the subclass (also called the 'instance type') are not stored in the database.

Properties

backing ↔ ManagedBacking: The persistent values of this object.
read / write
entity ↔ ManagedEntity: The ManagedEntity this instance is described by.
read / write
hashCode → int: The hash code for this object.

modelFieldIncludeIfNull → bool: latefinal
properties ↔ Map<String?, ManagedPropertyDescription?>: IMPROVEMENT: Cache of entity.properties to reduce property loading time
read / write
responseKeyProperties ↔ Map<String?, ManagedPropertyDescription?>: Cache of entity.properties using ResponseKey name as key, in case no ResponseKey is set then default property name is used as key
read / write
runtimeType → Type: A representation of the runtime type of the object.
