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.

Dart classes and constructors

Dart classes are declared by using the class keyword, followed by the class name, ancestor classes, and implemented interfaces. Then, the class body is enclosed by a pair of curly braces, where you can add class members, that include the following:

  • Fields: These are variables used to define the data an object can hold.
  • Accessors: Getters and setters, as the name suggests, are used to access the fields of a class, where get is used to retrieve a value, and the set accessor is used to modify the corresponding value.
  • Constructor: This is the creator method of a class where the object instance fields are initialized.
  • Methods: The behavior of an object is defined by the actions it can take. These are the object functions.

Refer to the following small class definition example:

class Person {
String firstName;
String lastName;

String getFullName...
