ObxValue<T extends RxInterface> class

A reactive widget similar to Obx, but manages a local state. Pass the initial data in the constructor. This is useful for simple local states, like toggles, visibility, themes, button states, etc.

Example:

ObxValue(
  (data) => Switch(
    value: data.value,
    onChanged: (flag) => data.value = flag,
  ),
  false.obs,
),
