when I am trying to list my folder directory with ionic-native file i am not getting any folders in result.

My Code:

this.platform.ready().then(() => 
 this.filesystem.listDir(this.filesystem.applicationStorageDirectory, '').then((result) => 
 console.log(result);
 /*result will have an array of file objects with 
 file details or if its a directory*/
 for (let file of result) 
 if (file.isDirectory == true && file.name != '.' && file.name != '..') 
 console.log("This is a folder");
 // Code if its a folder
 else if (file.isFile == true) 
 // Code if its a file
 console.log("This is a file");
 let name = file.name // File name
 console.log("file name: " + name);
 // let path = file.path // File path
 file.getMetadata(function (metadata) 
 let size = metadata.size; // Get file size
 )
 
 
 );
 );

I am using: "@ionic-native/file": "4.12.0",
With imports:
import File from '@ionic-native/file';

You have not passed the directory name in this.filesystem.listDir(this.filesystem.applicationStorageDirectory, '') you have to pass directory name in this method. You can get directory name from the this.filesystem.applicationStorageDirectory. First alert this.filesystem.applicationStorageDirectory and check which type of path you get.

If path is like :

file:///storage/emulator/0/somefolder

then get the directory name as following :

let appStorageDir = "file:///storage/emulator/0/somefolder";
let dirName = appStorageDir.substring(appStorageDir.lastIndexOf("/")+1);

If there is slash(/) in the last of path like :

file:///storage/emulator/0/somefolder/

then get the directory name as following :

let appStorageDir = "file:///storage/emulator/0/somefolder/";
appStorageDir = appStorageDir.substring(0,appStorageDir.lastIndexOf("/"));
let dirName = appStorageDir.substring(appStorageDir.lastIndexOf("/")+1);

Now pass that dirName in method as following :

this.filesystem.listDir(this.filesystem.applicationStorageDirectory, dirName)

Hope it will help you !!!
