I was using this widget with image preview with data bytes being available on MacOS platform. There is a field called withData to signal widget that bytes are available. Default value equals to kIsWeb.
Another exception was thrown: Null check operator used on a null value
Another exception was thrown: A RenderFlex overflowed by 99827 pixels on the bottom.

I was using this widget with image preview with data bytes being available on MacOS platform. There is a field called
withData
to signal widget that bytes are available. Default value equals tokIsWeb
.Somehow instead of using
withData
on https://github.com/flutter-form-builder-ecosystem/form_builder_file_picker/blob/7311405ed04a78a90e6ce7bcc48250ee11b12d20/lib/src/form_builder_file_picker.dart#L246,kIsWeb
was used. So on MacOS platform this was trying to read file from path (which is null) instead of bytes. That resulted in a red error box and stacktrace:
