The main() function is a top-level function in Dart that initiates the execution of the program. It is the Dart programming language’s most important and crucial feature. In a program, the main() function can only be used once.
The main() function is responsible for all kinds of execution, including user-defined statements, functions, and libraries. The program starts with the main() function, which contains variable declarations, functions, and user-defined executable statements.
void main()
{
//main() function body
}
An optional List <String> parameters may be used as function arguments. These parameters can be used if we need to influence our application from the outside.
The main() function returns void.
The code below shows a basic example of the use of main() function in Dart.
