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 it works...

flutter_launcher_icons is a command-line tool that allows you to create the launcher icon for your app and is compatible with iOS, Android, and even web and desktop apps.

In order to use flutter_launcher_icons, you need to add its dependency in the dev_dependencies node in your pubspec.yaml file. This is where you put the dependencies that will not be exported to the release app. 

The configuration of this package happens in the pubspec.yaml file with the following instructions: 

android: true
ios: true
image_path: "icons/scale.png"
adaptive_icon_background: "#DDDDDD"
adaptive_icon_foreground: "icons/scale.png"

Here you specify the following:

  • The target platforms for the icons (in this case android and ios)
  • The path of the source image for the icon with the image_path property
  • The color used to fill the background of the adaptive icon (Android only) with the adaptive_icon_background...
