DateTimePicker readOnly property not consistent with datetime_picker_formfield

[coleweinman]

When using the FormBuilderDateTimePicker, the keyboard jumps up and closes when the date picker shows. After looking at the DateTimePicker from datetime_picker_formfield, it looks like if readOnly is true, then this issue should be resolved. However, due to the way FormBuilderDateTimePicker is written, if readOnly is true, then enabled is set to false, which disables the whole widget. While I believe this keyboard issue is the fault of datetime_picker_formfield, there should be more control of making only the keyboard read-only, and the whole widget read-only.

Are there any workarounds or news for this issue?
I am having the same issue right now stopping me from using the package in production.
