  @override
  Widget build(BuildContext context) {

    final highlightFuture = syntaxHighlighter.highlight('dart', 'print("Hello, World!");');

    return FutureBuilder<TextSpan>(
      future: highlightFuture,
      builder: (context, snapshot) {
        if (snapshot.hasError) {
          return Center(child: Text('Error: ${snapshot.error}'));
        }
        
        final span = snapshot.data ?? const TextSpan(text: 'print("Hello, World!");');

        return SingleChildScrollView(
          padding: const EdgeInsets.all(16),
          child: SelectableText.rich(
            span,
            style: const TextStyle(fontFamily: 'monospace', height: 1.6),
