write_error_line method

@override void write_error_line(String text)

Writes an error message to the console, with newline automatically appended.

Implementation

@override
void write_error_line(
  final String text,
) {
  stderr.write(text);
  // Even if we're in raw mode, we write '\n',
  // since raw mode only applies to stdout.
  stderr.write('\n');
}
