Overview of this book

“Anyone interested in developing Flutter applications for Android or iOS should have a copy of this book on their desk.” – Amazon 5* Review Lauded as the ‘Flutter bible’ for new and experienced mobile app developers, this recipe-based guide will teach you the best practices for robust app development, as well as how to solve cross-platform development issues. From setting up and customizing your development environment to error handling and debugging, The Flutter Cookbook covers the how-tos as well as the principles behind them. As you progress, the recipes in this book will get you up to speed with the main tasks involved in app development, such as user interface and user experience (UI/UX) design, API design, and creating animations. Later chapters will focus on routing, retrieving data from web services, and persisting data locally. A dedicated section also covers Firebase and its machine learning capabilities. The last chapter is specifically designed to help you create apps for the web and desktop (Windows, Mac, and Linux). Throughout the book, you’ll also find recipes that cover the most important features needed to build a cross-platform application, along with insights into running a single codebase on different platforms. By the end of this Flutter book, you’ll be writing and delivering fully functional apps with confidence.

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.complete = false, this.description
= ''});
  1. 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 =,
description =['description'],
complete =[&apos...
