A function definition consists of actual statement that specifies what and how a specific task would do when called. Before using function, it must be defined. The syntax for defining a dart function is given below -
Syntax
void function_name(){
//statements
}
OR
function_name(){
//statements
}
The void keyword indicates that the function does not return any value to the caller.
Example- Defining Function
run(){
//function definition
print("Function calledd.");
}
