By Salvatore Giordano. At the moment I’m not really into writing Flutter code, and I miss it. I’ve changed jobs more or less 10 months ago. Now I’m a backend-microservices developer using Node.js as a primary tool, but after all this time I’m starting to miss Flutter, Dart and that great community. So, my new mission is to convince my engineering lead to let me rewrite our main application using Google’s cross-platform framework — Flutter.
Flutter is an application development framework from Google for creating cross-platform mobile applications (in iOS and Android). As mentioned on the official website, it aims to make the development as easy, quick, and productive as possible. Features such as Hot Reload, a vast widget catalog, very good performance, and a solid community contribute to meeting that objective and make Flutter a pretty good mobile development framework. This post is an excerpt from the book Google Flutter Mobile Development Quick Start Guide by Packt Publishing written by Prajyot Mainkar, and Salvatore Giordano.
When you write a program in Java for Android and click a button, your code is transformed into another form understood by Android. This other form is called Dalvik Executable, or DEX code, and the transformation process is called compiling. Android is a complex system, but you don’t need to understand it in depth to be able to make amazing apps. To get started, we only need to understand the basics.
