Dart function — Recursive Functions

Andrew Maung
Feb 12, 2022

recursive function is a function that calls itself. A recursive function is used for repeating code. If the state of the function does not change, and it has no preset exit condition that is reached, a recursive call can turn into an infinite loop.

void forever() { 
forever();
}

forever() is indeed an infinite loop. Here is a recursive function that will repeatedly add one String to

another String.

String addOn(String original, String additional, int times) { 
if (times <= 0) { // exit condition to end "recursive loop"
return original;
}
return addOn(original + additional, additional, times - 1);
// recursive call
}
