Service Status

Classify Check Counts

Dart programs often turn a small numeric signal into a clear status label. This example keeps the check count and threshold explicit so the report line stays easy to inspect.

Program

Play the program to choose the failed check count and inspect the service status line.

service_status_model.dart 
String classify(int failedChecks, int maxAllowed) {
  if (failedChecks <= maxAllowed) {
    return 'ready';
  }
  return 'blocked';
}

void main() {
  var failedChecks = ;
  var maxAllowed = 0;
  var status = classify(failedChecks, maxAllowed);
  var line = 'api failed=$failedChecks status=$status';
  print(line);
}

String classify(int failedChecks, int maxAllowed) {
  if (failedChecks <= maxAllowed) {
    return 'ready';
  }
  return 'blocked';
}

void main() {
  var failedChecks = ;
  var maxAllowed = 0;
  var status = classify(failedChecks, maxAllowed);
  var line = 'api failed=$failedChecks status=$status';
  print(line);
}
status function `classify` isolates the ready/blocked decision from the reporting string.
threshold `maxAllowed` makes the policy visible instead of hiding it in a magic label.
report line The final string combines the service signal and the derived status.
