# newLine method

Future<void> newLine()

Writes a line separator.

The line separator string is defined by the system property line.separator, and is not necessarily a single newline character ('\n').

## Example

    final writer = FileWriter('output.txt');
    try {
      await writer.write('First line');
      await writer.newLine();
      await writer.write('Second line');
      await writer.newLine();
      await writer.flush();
    } finally {
      await writer.close();
    }

Throws IOException if an I/O error occurs. Throws StreamClosedException if the writer has been closed.

## Implementation

    Future<void> newLine() async {
      await writeChar(10); // '\n' - simplified for cross-platform compatibility
    }
