dart function

when you want to make a function that 
doesn't use the format return or a function that doesn't return a value
the function base will look like this:

void functionName() {

}

if its returning some thing it will look like this:

functionName() {
	
}

  func2();
  func3(45, 6);
  print("Division 1:${func4()}");
  print("Division 2:${func5(22, 7)}");
  print(PrintMsg());
}

void func1() {

void func2() {
  var num1 = 12;
  var num2 = 45;
  var num3 = 0;
  num3 = num1 + num2;

void func3(var num1, var num2) {
  var num3 = 0;
  num3 = num1 * num2;
  print("Multiply:$num3");
}

double func4() {
  var num1 = 22.0;
  var num2 = 7.0;
