Learn Flutter With Real-World Examples

Flutter is an incredible toolkit that lets you build iOS and Android apps from a single codebase. The official documentation does a great job covering a lot of the basics. These basics can get you pretty far, even let you create apps ready for publishing on the app stores. But to take your apps to the next level, it helps to see lots of real-world examples.

This is where Real-World Flutter by Tutorials comes to the rescue! In this book, you'll learn how to build professional iOS and Android apps for the real world. You'll gain all the foundations of mobile development you need to make the best decisions in your own codebase while addressing critical problems such as state management, user authentication and dynamic theming.

Who This Book is for

This book is for Flutter developers looking to go from "I know Flutter" to "I can confidently create professional Flutter apps".

“To my brother, Caio, who’s the only person on this list who will actually read this book – because I’ll make him. To my mom, Van, and my dad, Edson, for the unconditional love and support. To Will, my brother from another mother, and Paola, my sister from another mister, for being my partners in crime whenever I needed to decompress from this work. To Juanderson, my eternal roomie, who has always cheered for me. Lastly, to my teacher Kamila and my first employers, Ricardo and Tiago, without whom I’d probably be making my living doing something shameful to my family, like, I don’t know, coding PHP.”

“To my parents, Irena and Božidar, and my sister, Teja, who supported me growing up and shaped me into the person I am today. To my best friend Anej and his mobile app project, on which we worked as students. It was my first experience with Flutter and mobile development in general, and today this has grown into something I do for a living. To my friends, Albina and Jure, who always understood when I had to work instead of having fun with them. And to the coauthor of this book, Edson, and the rest of the team that allowed me to learn from them while writing this book and being patient when I needed time.”
