newLine method
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
}
