flutterdownloader not downloading a file again which is already deleted

Question

await FlutterDownloader.enqueue(
          url: Uri.parse(url).toString(),
          savedDir: fullPath,
          fileName: actualFileName,
          showNotification: true,
          openFileFromNotification: true,
          saveInPublicStorage: true);

When deleting file from the file explorer and download the same file again always failing

In iOS it is working, Issue with android device only.

Steps:

1. download a file (FlutterDownloader.enqueue())
2. delete the file manually from downloads
3. download the same file FlutterDownloader.enqueue())

Anyone please help me to resolve this

Note: deleted file name and new download attempt file name same

Answer 1

I think this issue you are facing with the FlutterDownloader plugin on Android seems related to how the file deletion is handled. When you delete a file and then attempt to download the same file again, the FlutterDownloader might still be referencing the old file path which no longer exists, leading to a NullPointerException.

To resolve this issue, try the following steps

1. Clear Cached File Path 2.Check File Permissions
2. Update Plugin
3. Debug Log Analysis
