我构建了一个包含视频的应用。我尝试从应用程序目录中获取所有文件，但收到此问题，我不知道如何解决。
谁能解释一下如何解决这个问题？
import 'dart:io';
import 'package:path_provider/path_provider.dart';
Future<List<FileSystemEntity>> getAllVideos() async {
final extDir = await getApplicationDocumentsDirectory();
final dirPath = '${extDir.path}/media';
final myDir = Directory(dirPath);
List<FileSystemEntity> vidoes;
try {
vidoes = myDir.listSync(recursive: true, followLinks: false);
vidoes.sort((a, b) {
return b.path.compareTo(a.path);
});
} catch (e) {}
return vidoes;
}
