Command, of type ICommand, defines the command that's executed when the button is tapped.
When the Button is pressed with a finger or clicked with a mouse it initiates that command. A Button usually displays a short text string indicating a command, but it can also display a bitmap image, or a combination of text and an image. NET Multi-platform App UI (.NET MAUI) Button displays text and responds to a tap or click that directs the app to carry out a task.
