render method

@override String render()

Renders the component as a styled string.

Subclasses implement this to produce their ANSI-styled output.

Implementation

@override
String render() {
  final width = renderConfig.terminalWidth;

  if (text == null) {
    return char * width;
  }

  final label = ' $text ';
  final remaining = width - Style.visibleLength(label);
  final safeRemaining = remaining > 0 ? remaining : 0;
  final left = safeRemaining ~/ 2;
  final right = safeRemaining - left;

  return '${char * left}$label${char * right}';
}
