# removePortNameMapping method

bool removePortNameMapping (String name)

Removes a name-to-SendPort mapping given its name.

Returns true if the mapping was successfully removed, false if the mapping did not exist. To add a registration, consider registerPortWithName.

Generally, removing a port name mapping is an inherently racy operation (another isolate could have obtained the name just prior to the name being removed, and thus would still be able to communicate over the port even after it has been removed).

The `name` argument must not be null.

## Implementation

    static bool removePortNameMapping(String name) {
      assert(name != null, "'name' cannot be null.");
      return _removePortNameMapping(name);
    }
