# writeln method Null safety

void writeln (

1. [Object? object = ""]

)
inherited

Converts `obj` to a String by invoking Object.toString and writes the result to `this`, followed by a newline.

This operation is non-blocking. See flush or done for how to get any errors generated by this call.

## Implementation

    void writeln([Object? object = ""]) {
      _sink.writeln(object);
    }
