Build your Apps With Flutter! Flutter is an exciting development toolkit that lets you build apps for iOS, Android and even web and desktop, all from a single codebase. It uses a declarative approach to UI development. You can hot reload code while developing, and apps will perform at native speed thanks to its custom rendering engine. With Flutter and Flutter Apprentice, you can achieve the dream of building fast applications, faster. Flutter is an incredible user interface (UI) toolkit that lets you build apps for iOS and Android - and even the web and desktop platforms like macOS, Windows and Linux - all from a single codebase. Flutter has all the benefits of other cross-platform tools, especially because you're targeting multiple platforms from one codebase. Furthermore, it improves upon most cross-platform tools thanks to a super-fast rendering engine that makes your Flutter apps perform as native apps. In addition, Flutter features are generally independent of native features, since you use Flutter's own type of UI elements, called widgets, to create your UI. And Flutter has the ability to work with native code, so you can integrate your Flutter app with native features when you need to. If you're coming from a platform like iOS or Android, you'll find the Flutter development experience refreshing! Thanks to a feature called "hot reload", you rarely need to rebuild your apps as you develop them. This book is for developers who are new to Flutter, and also developers that already have some experience with building apps for the iOS and Android platforms, or web apps.
