Flutter for Beginners

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.

Debugging your app

Debugging is an important part of software development. Small mistakes, strange behaviors, and complex bugs can be solved with the help of debugging. With debugging, we can do the following:

  • Make logic assertions
  • Determine the required improvements
  • Find memory leaks
  • Perform flow analysis

Flutter provides multiple tools to help you debug your app, but the easiest way to debug is via the IDE, so let’s start there.

Debugging in the IDE

To be able to debug within your IDE, you first need to run your app from within your IDE. If you are running Visual Studio Code, then you will see a RUN AND DEBUG button on the left-hand side of the IDE, which looks like an arrow with a bug on it. Click this; at the top of the section, you will see a Run debugging button beside the name of the Flutter project, hello_world:
