fileExtensionsFilter not filtering about flutter_file_dialog HOT 2 CLOSED

Did you try "application/json"? Search from Internet with keyword "EXTRA_MIME_TYPES" for more information about supported mime types. There is probably nothing that can be in this plugin to improve this.

from flutter_file_dialog.

I replaced with the following code and it still does not filter (unless with Android 11, the only filtering is making those files that match selectable, while still showing everything in a folder):

 final params = OpenFileDialogParams(
        dialogType: OpenFileDialogType.document,
        allowEditing: false,
        allowedUtiTypes: [
          'json'
        ], // TODO: Register UITypes in iOS info.plist https://developer.apple.com/library/archive/qa/qa1587/_index.html
        mimeTypesFilter: ['application/json'],
        localOnly: false,
      );
