Overview of this book

Xamarin.Forms is a lightweight cross-platform development toolkit for building applications with a rich user interface. In this book you'll start by building projects that explain the Xamarin.Forms ecosystem to get up and running with building cross-platform applications. We'll increase in difficulty throughout the projects, making you learn the nitty-gritty of Xamarin.Forms offerings. You'll gain insights into the architecture, how to arrange your app's design, where to begin developing, what pitfalls exist, and how to avoid them. The book contains seven real-world projects, to get you hands-on with building rich UIs and providing a truly cross-platform experience. It will also guide you on how to set up a machine for Xamarin app development. You'll build a simple to-do application that gets you going, then dive deep into building advanced apps such as messaging platform, games, and machine learning, to build a UI for an augmented reality project. By the end of the book, you'll be confident in building cross-platforms and fitting Xamarin.Forms toolkits in your app development. You'll be able to take the practice you get from this book to build applications that comply with your requirements.

A Matchmaking App with a Rich UX Using Animations

In this chapter, we will create the base functionality for a matchmaking app. We won't be rating people, however, because of privacy issues. Instead, we will download images from a random source on the internet. This project is for anyone who wants an introduction to how to write reusable controls. We will also look at using animations to make our application feel nicer to use. This app will not be an MVVM application, since we want to isolate the creation and usage of a control from the slight overhead of MVVM.

The following topics will be covered in this chapter:

  • Creating a custom control
  • How to style the app to look like a photo with descriptive text beneath it
  • Animations using Xamarin.Forms
  • Subscribing to custom events
  • Reusing the custom control over and over again
  • Handling pan gestures
