i think this issue because condition (T == String || compareFn != null) not met, you can add or add compareFn: (item1, item2) => true,

like this :

Widget _masterCheckPoint() { return FormBuilderSearchableDropdown( name: 'mstr_id', decoration: const InputDecoration( hintText: 'Check Point', label: Text('Check Point'), ), validator: FormBuilderValidators.compose([ FormBuilderValidators.required(), ]), asyncItems: (String? filter) => _controller.getMasterCheckPoint(filter), compareFn: (item1, item2) => true, popupProps: const PopupProps.menu( showSearchBox: true, ), ); }

This is not a bug, either your generic type has to be a string, or you have to implement the custom compare function.
