what expected have getExternalStorageDirectory() of path_provider dependency?

问题

I have an application that i develop with flutter and i need to acces local storage. what is expected return of that code?

i use the package path_provider:^1.2.2

var directory=await getExternalStorageDirectory();
print(directory.path)

I obtains: /storage/emulated/0/Android/data/com.myapplication.application/files

while i expect to have /storage/emulated/0/.

I want to know if is not an error.

回答1:

Remove the .getAbsolutePath() and it will be fine. Environment.getExternalStoreDirectory() will give you the path to wherever the manufacture has set its external storage. https://api.dartlang.org/stable/2.4.1/dart-core/String/substring.html for trimming path as you need...

回答2:

another solution is to do like that

Directory directory = await getExternalStorageDirectory();
List<String> segment = directory.uri.pathSegments;
String rootPath = "/" + segment[0] + "/" + segment[1] + "/" + segment[2];
print(rootPath);

and you obtains /storage/emulated/0
