I am using file_picker plugin for document pick from device but it doesn't work

I am getting this error below steps:

1. First time click on button and trying to open file explorer but did not open. i mention error below

[Presentation] Attempt to present <UIDocumentPickerViewController: 0x10c736ca0> on <UINavigationController: 0x10d80e000> (from <FlutterViewController: 0x10c816800>) whose view is not in the window hierarchy.

2. Second time click on button and getting this error below

flutter: [MethodChannelFilePicker] Platform exception: PlatformException(multiple_request, Cancelled by a second request, null, null)
flutter: Unsupported operationPlatformException(multiple_request, Cancelled by a second request, null, null)

Please any suggestions.

Hi, this have already been opened and it’s likely related to an implementation issue on the app’s side. Just make sure you’re calling the picker once and awaiting for the result before invoking again.
