Overview of this book

There have been many attempts at creating frameworks that are truly cross-platform, but most struggle to create a native-like experience at high-performance levels. Flutter achieves this with an elegant design and a wealth of third-party plugins, solidifying its status as the future of mobile app development. If you are a mobile developer who wants to create rich and expressive native apps with the latest Google Flutter framework, this book is for you. You’ll start with the basics of cross-platform development frameworks, specifically Flutter. You’ll then explore the Dart programming language which is the foundation of the Flutter framework. Next, you’ll get a feel for Flutter and how to create your first app, followed by an exploration of the various popular plugins that supplement the Flutter framework. Finally, you’ll explore testing and app release, including some common glitches that you may experience. By the end of this book, you’ll be well-equipped to create and release a basic Flutter app along with gaining a solid understanding of the Flutter framework and Dart language.

Flutter supports many image formats out of the box (i.e., there is no plugin or specific platform support required):

  • JPEG – This stands for Joint Photographic Experts Group. It is a very common format predominantly used for photography. It uses lossy compression (meaning that as the image is compressed to reduce size, it loses details about the image) and is the most widely used image format because it suits photographic compression very well. However, it is really not well suited to line drawings or iconography because the compression process can create artifacts in the image.
  • PNG –...
