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...

Let's update the previous recipe's code with some new fonts:

  1. Open the pubspec.yaml file in the root folder of your project. 

  2. In the pubspec.yaml file, add the google_fonts package in the dependencies section, but be careful. YAML is one of the few languages where white space matters, so be sure to put the google_fonts dependency precisely under flutter, as shown here:

sdk: flutter
google_fonts: ^2.0.0
  1. After this is done, run flutter packages get to rebuild your asset bundle.

  2. We can now add any Google font to the text widgets in text_layout.dart.  Add the google_fonts  import at the top of the file:

import 'package:google_fonts/google_fonts.dart';
  1. Update the first Text widget to reference the leckerliOne font:
'Hello, World!',
style: GoogleFonts.leckerliOne(fontSize: 40),

The leckerliOne font will now be rendered on the screen:

  1. Now you will...
