Overview of this book

Google Flutter is a cross-platform mobile framework that makes it easy to write high-performance apps for Android and iOS. This book will help you get to grips with the basics of the Flutter framework and the Dart programming language. Starting from setting up your development environment, you’ll learn to design the UI and add user input functions. You'll explore the navigator widget to manage app routes and learn to add transitions between screens. The book will even guide you through developing your own plugin and later, you’ll discover how to structure good plugin code. Using the Google Places API, you'll also understand how to display a map in the app and add markers and interactions to it. You’ll then learn to improve the user experience with features such as map integrations, platform-specific code with native languages, and personalized animation options for designing intuitive UIs. The book follows a practical approach and gives you access to all relevant code files hosted at github.com/PacktPublishing/Flutter-for-Beginners. This will help you access a variety of examples and prepare your own bug-free apps, ready to deploy on the App Store and Google Play Store. By the end of this book, you’ll be well-versed with Dart programming and have the skills to develop your own mobile apps or build a career as a Dart and Flutter app developer.

Improving User Experience

If you want your application to reach a high level, you need to keep it open to continuous interaction with user context, even though it is not currently running. In addition, developing an internationalized and fully accessible app allows it to grow progressively. In this chapter, you'll learn how to create processes executed in the background, translate your app into the target language, and add accessibility features that improve the usability of the app.

The following topics will be covered in this chapter:

  • Accessibility in Flutter
  • Adding translations to apps
  • Communication between native and Flutter with platform channels
  • Creating background processes
  • Adding Android-specific code to run Dart code in the background
  • Adding iOS-specific code to run Dart code in the background
