final imageBytes = await Pasteboard.image;

import 'dart:typed_data';

Future<void> readImageFromClipboard() async {
  try {
    // 从剪贴板读取图片数据
    final Uint8List? imageBytes = await Pasteboard.image;
    
    if (imageBytes != null) {
      // 成功获取图片数据
      print('图片大小: ${imageBytes.length} bytes');
      // 可以将其转换为 Image widget 显示
      // Image.memory(imageBytes)
    } else {
      // 剪贴板中没有图片
      print('剪贴板中没有图片数据');
    }
  } catch (e) {
    print('读取剪贴板失败: $e');
  }
}
