# getIsolateID method Null safety

String? getIsolateID (

1. Isolate isolate

)

Returns a String token representing the ID of `isolate`.

Returns null if the running Dart environment does not support the service protocol.

## Implementation

    static String? getIsolateID(Isolate isolate) {
      // TODO: When NNBD is complete, delete the following line.
      ArgumentError.checkNotNull(isolate, 'isolate');
      return _getIsolateIDFromSendPort(isolate.controlPort);
    }
