Create apps for iOS and Android phones and tablets using Flutter, a Google framework that produces two outputs for a single app. Let's face it, creating iOS apps using Apple tools such as Swift and Xcode is extremely complicated. Creating Android apps with Kotlin and Android Studio is just as difficult. This book breaks down complex concepts and tasks into easily digestible segments with examples, full-color pictures, and hands-on labs with starters and solutions.
As you work through the accompanying lab exercises, you'll learn the Dart programming language; the entire Flutter development toolchain; the differences between stateful and stateless widgets; and a working knowledge of the architecture of apps. Youll work with themes and styles, develop custom widgets, and even teach your app to respond to gestures like taps, swipes, and pinches. Youll also design, create, and control the layout of your app. Create tools to handle form data entry from users. And ultimately create killer multiscreen apps with navigation, menus, and tabs.
Youll see that with Flutter, you can write an app one time that produces two outputs: one that can be submitted to the Apple App Store and another that can be uploaded to the Google Play Store. In short, one code creates the same app that runs on iPhones, iPads, Android phones and tablets, virtually all devices. And if you like, it can also create a version that runs on Macs, Windows, Linux, and in browsers!
Flutter App Development explains difficult topics in plain, everyday terms that simplify the process of writing mobile apps.
