• 如何在挥霍乱中找到根的目录
原标题:How to get the root directory path in Flutter

这一问题有其成因,还是可以通过<条码>dart:io解决,因为path_provider。 没有任何办法获得根基目录?

问题回答

您可以利用这一功能:

import  dart:io ;

Directory findRoot(FileSystemEntity entity) {
    final Directory parent = entity.parent;
    if (parent.path == entity.path) return parent;
    return findRoot(parent);
}

如果您有以下一揽子计划,如path_provider,你可以在你的法典中使用:

import  package:path_provider/path_provider.dart ;

final Directory root = findRoot(await getApplicationDocumentsDirectory());

首先安装花板:

flutter pub add external_path

然后进口:

import  package:external_path/external_path.dart ;

最后,情况如下:

var path = await ExternalPath.getExternalStorageDirectories();  // [/storage/emulated/0, /storage/B3AE-4D28] 2nd path refers to SD
