Use this skill when the user wants to use the single_value_cubit package, wire simple Flutter state with a Cubit, bind text fields to cubits, toggle boolean state with toggle(), clear string state with erase(), increment or decrement integer state with increment()/decrement(), use StringInputCubit for text inputs, use IntValueCubit for integer counters or quantities, observe a Bloc/Cubit stream with the current value emitted immediately via observe(), or use SingleValueBoolCubitExtension/SingleValueStringCubitExtension/SingleValueIntCubitExtension. Trigger this whenever the task involves lightweight single-value state such as inputs, flags, counters, quantities, scroll positions, filters, or replacing ad hoc ValueNotifier or basic Cubit boilerplate with single_value_cubit. MUST trigger for any question about StringInputCubit, IntValueCubit, SingleValueCubit, single value cubit.
