Here is the source code used in this chapter:Â https://github.com/PacktPublishing/Delphi-GUI-Programming-with-FireMonkey/tree/master/Chapter%2001/HelloWorld.
Generally speaking, for the whole book, you need a computer with Delphi set up and a few additional libraries installed (such as Radiant Shapes (https://getitnow.embarcadero.com/?q=radiant+shapes) and CodeSite Logging (https://getitnow.embarcadero.com/?q=codesite)). Having other physical devices and setting up multiple platforms (iOS, Android, OS X/macOS, and Linux) other than Windows is a plus but not strictly needed to follow the flow of the book.
