Create almost empty Flutter project with "hello world" App:

By default, when creating a new Flutter app project with the flutter create
command, a counter app project will get generated. Instead of deleting the unwanted pieces of code every time I create a new project I wondered if there was a way to create an even more basic, more empty project. First, we are going to create a simpler version of the Counter App project and from there transform it into a generic "hello world" app.
