Flutter First Steps
Building iOS and Android apps and websites with a single codebase
Topic: Web & Mobile
Flutter is the framework that finally puts developing apps in the reach of mere mortals, whether your app is aimed at iOS devices, Android devices, or even a website. And when you write the code for any one of those platforms, it runs—natively—in all three.
Join expert Rap Payne to build the key skills you need to begin writing apps in Flutter. By the time you’re through, you’ll be able to create your own Flutter app that takes input from the user, lays out nicely on any screen, and presents information in a way that’s beautiful and fast.
What you'll learn-and how you can apply it
By the end of this live online course, you’ll understand: - The problems Flutter solves - Flutter’s strengths and weaknesses relative to other options - The architecture of a Flutter app - How and why Flutter uses widgets and composition - The Dart language: How it’s similar to other languages and how it’s different - Foundational widgets like MaterialApp, Scaffold, Text, Icon, TextField, the button family, and more
And you’ll be able to: - Create a new Flutter app - Write your own widgets, whether stateless or stateful - Manage state within a widget - Create gorgeous user interfaces that run on iOS, Android, and the web - Handle basic stack navigation to move between screens
This training course is for you because...
- You’re an experienced developer who wants to create apps and websites.
- You’re a manager or architect who wants to evaluate a new tool for your team.
- A working knowledge of object-oriented development
Recommended preparation: - A machine with the Flutter developer tools installed (The installation can be time-consuming because there are so many different combinations of operating systems, hardware, and other tools; please follow these step-by-step instructions before the course.) - Read chapters 1–4 in Beginning App Development with Flutter: Create Cross-Platform Mobile Apps (book)
Recommended follow-up: - Finish Beginning App Development with Flutter: Create Cross-Platform Mobile Apps (book) - Watch Learn Flutter and Dart to Build iOS and Android Apps (video) - Read “Introduction to Dart” and “The Flutter User Interface - Everything Is a Widget” (sections 1 and 2 in Flutter for Beginners)
