I'm not able to add images after new version upgrade

Yikes! I think I see the problem:

https://github.com/danvick/flutter_form_builder/blob/d4f862d662242a4887c03613260791a0f3f660b8/lib/src/fields/form_builder_image_picker.dart#L187

When field.value is null, this triggers an NPE. This needs a null-safe operator like ...?.

In the meantime, you can try specifying an empty list as initialValue -- that should be a viable workaround to avoid the null.

Thanks for the quick resolution. It's definitely a great package to use in the flutter apps.

It's a basic bug. It appears that unit tests are not here. How can we help?
