Next Continue in Dart

In Dart, next and continue keywords are used in loops to control the flow of the loop iteration.

Next statement is used when we want to skip a particular value of the loop without terminating the loop. The continue statement can only be used inside loops.

Here is an example of using the next statement in a loop-

void main() {
  for (int i = 0; i < 6; i++) {
    if (i == 3) {
      continue;   //skip the rest when i=3
    }
    print("Value of i: $i");
  }
}
/* Output:

Value of i: 0

Value of i: 1

Value of i: 2

Value of i: 4

Value of i: 5

*/

In the above example, the loop will print all values of i except when i is 3, due to the use of continue statement.

Next, let's look at the continue statement in a loop.

Here is an example of using the continue statement in a while loop.

void main() {
  int i = 0;
  while (i < 6) {
    i++;
    if (i == 3) {
      continue;   //skip i=3 and continue the loop
    }
    print("Value of i: $i");
  }
}
/* Output:

Value of i: 1

Value of i: 2

Value of i: 4

Value of i: 5

Value of i: 6

*/

In the above example, the loop will print all values of i except when i is 3, due to the use of continue statement.

So, both next and continue statement are helpful in controlling the flow of the loop iteration in Dart.
