Break and continue

Use break to stop looping:

while (true) {
  if (shutDownRequested()) break;
  processIncomingRequests();
}

Use continue to skip to the next loop iteration:

for (int i = 0; i < candidates.length; i++) {
  var candidate = candidates[i];
  if (candidate.yearsExperience < 5) {
    continue;
  }
  candidate.interview();
}

You might write that example differently if you’re using anIterable such as a list or set:

candidates
    .where((c) => c.yearsExperience >= 5)
    .forEach((c) => c.interview());
