Web: FIlePickerResult.xFiles crashes when withData: false

[eggzotic]

Describe the bug After selecting file(s) on web, any access to the xFiles property of the result results in:

Error

Similarly, attempting to stick with the files property, and accessing the converter PlatformFile.xFile also crashes like above.

By comparison, on MacOS (native), the xFiles properties are accessible. Also, using withData: true works on both platforms (web & other).

I intend to pass the xFile objects to other code which will handle opening/reading the files (sometimes large!) so do not want the data pre-read. Is there a workaround or fix known for this?

How are you picking?

pickerResult =
   await FilePicker.platform.pickFiles(
     dialogTitle: "Select file(s) for upload",
     allowMultiple: true,
     withData: false,
     allowCompression: false,
     withReadStream: false,
   );
   debugPrint("Filepicker closed");
   if (pickerResult == null || pickerResult.files.isEmpty) return;
