Cross-Platform UIs with Flutter

By: Ryan Edge, Alberto Miola

Overview of this book

Flutter is a UI toolkit for building beautiful, natively compiled applications for mobile, web, desktop, and embedded devices from a single code base. With Flutter, you can write your code once and run it anywhere using a single code base to target multiple platforms. This book is a comprehensive, project-based guide for new and emerging Flutter developers that will help empower you to build bulletproof applications. Once you start reading book, you’ll quickly realize what sets Flutter apart from its competition and establish some of the fundamentals of the toolkit. As you work on various project applications, you’ll understand just how easy Flutter is to use for building stunning UIs. This book covers navigation strategies, state management, advanced animation handling, and the two main UI design styles: Material and Cupertino. It’ll help you extend your knowledge with good code practices, UI testing strategies, and CI setup to constantly keep your repository’s quality at the highest level possible. By the end of this book, you'll feel confident in your ability to transfer the lessons from the example projects and build your own Flutter applications for any platform you wish.

Building a Race Standings App

In this chapter, we’ll create a more complex project than the counter app we built previously. We’re going to create the UI of a generic racing game that shows both the results of races and drivers’ standings.

Other than code quality, we will also pay a lot of attention to the user experience (UX); this includes localization, internationalization, responsiveness, color contrast, and more, which will be used to create a high-quality result. We will also learn how to manually work with the device’s pixels with CustomPainter, for those cases where Flutter widgets aren’t enough.

In this chapter, we will cover the following topics:

  • Creating responsive screens using the LayoutBuilder widget
  • Using the intl package to localize the app
  • Working with images – PNGs and vectorial files
  • Using custom painters to paint complex UI elements

Let’s get started!
