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...

To implement separation of concerns for views and models, follow these steps: 

  1. The best place to start is the data layer. This will give you a clear view of your app, without going into the details of your user interface. In the models folder, create a file called task.dart and create the Task class. This should have a description string and a complete Boolean, as well as a constructor. This class will hold the task data for our app. Add the following code:
class Task {
String description;
bool complete;

this.complete = false,
this.description = '',
  1. We also need a plan that will hold all our tasks. In the models folder, create plan.dart and insert this simple class:
import './task.dart';

class Plan {
String name = '';
final List<Task> tasks = [];
  1. We can wrap up our data layer by adding a file that will export both models. That way, our imports will not get too bloated as the app grows...
