Flutter App Development: How to Write for iOS and Android at Once

One Flutter codebase can serve as the starting point for apps on both iOS and Android. In Flutter App Development: How to Write for iOS and Android at Once, Rap Payne walks through the framework’s building blocks—from project setup and Dart to widgets, layout, and app behavior—so readers can see how the pieces fit together.

From the first project to a working interface

The book begins with the Flutter toolchain and the anatomy of a project, then turns to widgets: the components used to build an app’s interface. It explores built-in and custom widgets, value widgets, forms, and the distinction between stateless and stateful designs. That progression helps connect individual interface elements to the larger structure of an app.

Make apps respond and move

Tap, swipe, pinch, and long-press interactions are among the gestures covered. Payne also introduces navigation and routing, including moving between screens, returning results, and using dialogs, tabs, and menus to shape a multiscreen experience.

Handle state, data, and presentation

Further chapters address state management, including libraries such as Riverpod, calls to RESTful APIs, themes, and the practical work of laying out and positioning widgets. Together, these topics show how interface choices, changing data, and app structure work alongside one another.

A practical route into Flutter

Examples and hands-on labs accompany the explanations. The book is intended for developers who have programmed in languages such as JavaScript, Python, Java, C#, or C++, and may also help managers, product owners, and business analysts understand what Flutter can do.
