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...

While on an Android device you can install an unsigned app, this is not possible on iOS devices. Apps must be signed first.

This is why you need a provisioning profile. It is a link between the device and the developer account and contains information that identifies developers and devices. It is downloaded from your developer account and included in the app bundle, which is then code-signed.

Once you have a provisioning profile, you should keep it in a safe and easy-to-retrieve space; this is why the first step in this recipe was creating a private Git repository. 

In this recipe, you created two provisioning profiles:

  • A development provisioning profile. You created it with the fastlane match development command. This must be installed on each device on which you wish to run your application code; otherwise, the app will not start.
  • A distribution profile with the fastlane match appstore command. This allows distributing an app on any device,...
