# lookupPortByName method

SendPort lookupPortByName (String name)

Looks up the SendPort associated with a given name.

Returns null if the name does not exist. To register the name in the first place, consider registerPortWithName.

The `name` argument must not be null.

## Implementation

    static SendPort lookupPortByName(String name) {
      assert(name != null, "'name' cannot be null.");
      return _lookupPortByName(name);
    }
