dart : check if a directory exist

Question

In Dart would like to check if a directory exist but without knowing a substring of this directory :

eg :

dir = preview/1552146038702.jpg.1--001--001.html.test.jpg

I tried :

io.Directory(await dir).exists().then((exist){

but in the dir I don't know 1--001--001.html

Any idea?

Answer 1

This works for me, hope my answer help

final path = '/storage/emulated/0/Download';
final checkPathExistence = await Directory(path).exists();

Answer 2

Directory.exists() provides this information

bool exists = await Directory(path).exists();
