You miss this snip codes in your manifest:

<provider
     android:name="vn.hunghd.flutterdownloader.DownloadedFileProvider"
     android:authorities="${applicationId}.flutter_downloader.provider"
     android:exported="false"
     android:grantUriPermissions="true">
      <meta-data
          android:name="android.support.FILE_PROVIDER_PATHS"
          android:resource="@xml/provider_paths"/>
</provider>

If you want to prevent other applications from accessing your files, you should save them into the internal storage. See detail here
