Every program needs the
main()function, from which code execution begins. Thevoidis a type of function. We will talk about types of functions in the future; -
Dart code is written in the function's body, that is, in curly braces
{}. The space in the curly brackets{}is the function's body, in which we will write all the commands that will work in this function; -
Look at the semicolon
;. After each line of code, we put a semicolon. Otherwise, the development environment will report an error to us. Such line separation is necessary so that the dart interpreter knows where one instruction ends and where another begins.
