如何在flutter中将图像临时存储到文件中？

dependencies:
  flutter:
    sdk: flutter
  path_provider: ^2.0.3

import 'package:path_provider/path_provider.dart';

Future<File> saveImageToTempFile(Uint8List imageBytes) async {
  // 获取临时目录路径
  Directory tempDir = await getTemporaryDirectory();
  // 创建一个临时文件
  File tempFile = File('${tempDir.path}/temp_image.png');
  // 将图像字节写入文件
  await tempFile.writeAsBytes(imageBytes);
  return tempFile;
}

Uint8List imageBytes = ... // 获取图像字节数据
File tempFile = await saveImageToTempFile(imageBytes);
