How to do it...

This recipe will be divided into two components – serialization and integration. We're going to start with the serialization functions and then snap together all the pieces that we built over the last three recipes:

1. Open task.dart and add an id property and a default constructor. This will allow the Task model to be transformed into a generic Model:

import 'package:flutter/foundation.dart';
import '../repositories/repository.dart';

class Task {
  final int id;
  String description;
  bool complete;

  Task({@required this.id, this.complete = false, this.description
    = ''});
}

2. Now, we need to add the serialization and deserialization methods. These functions will take the data from a generic Model and return a more usable strongly typed object. Add the following code immediately after the constructor.

Task.fromModel(Model model)
 : id = model.id,
   description = model.data['description'],
   complete = model.data[&apos...
