ControlledComponentData<T> class
Immutable data container for controlled component state.
This class encapsulates the three essential pieces of state that controlled components need: the current value, a change callback, and the enabled status. It provides a convenient way to pass this state to widget builders.
The generic type T
represents the type of value being managed.
