Until in Dart

In Dart, the until loop is a loop control statement that executes a block of code repeatedly until a given condition becomes true. This loop is similar to the while loop, but the difference is that the block of code is executed before checking the condition.

The syntax for the until loop is:

do {
  // block of code to be executed
} until (condition);

Here is an example of using the until loop to print numbers from 1 to 5:

void main() {
  int i = 1;
  do {
    print(i);
    i++;
  } until (i > 5);
}

This will output the following:

1
2
3
4
5

Note that the do loop is executed at least once before checking the condition i > 5. Once i becomes greater than 5, the loop terminates.
