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.

Theming and Styling

Creating UIs with built-in themes and styles will make an application look professional and easy to use. In addition, the framework allows the creation of customized and unique themes and styles. In order to do that, you will learn how to customize an app's look by adding custom fonts, using themes, and exploring the famous platform standards, namely iOS Cupertino and Google Material Design. Additionally, you will see how to use media queries for dynamic styling.

Every app must have its own identity. Our Favors app, for example, needs to have its own colors and styles. Knowing how to apply styles, colors, and custom fonts is fundamental to achieve this in any app.

The following topics will be covered in this chapter:

  • Theme widgets
  • Material Design
  • iOS Cupertino
  • Using custom fonts
  • Dynamic styling with MediaQuery and LayoutBuilder
