Flutter删除目录文件 [英] Flutter delete Directory file

问题描述

我要删除目录中的文件。

final Directory extDir = await getTemporaryDirectory();
final String dirPath = '${extDir.path}/video';
await new Directory(dirPath).create(recursive: true);
final String filePath = '$dirPath/${timestamp()}.mp4';

我想删除此特定路径，以使应用程序不会繁琐。
我该怎么做？

有人有想法吗？

I want to delete this specific path so that app won't heavy. How can I do this?
Does anyone have an idea?

推荐答案

无需移动到目录。您将路径传递到 Directory 构造函数：

You don't need to move to the directory. You pass the path to the Directory constructor:

import 'dart:io';

void main() {
    final dir = Directory(dirPath);
    dir.deleteSync(recursive: true);
}
