- Ephemeral state (sometimes called UI state or local state) is the state you can neatly contain in a single widget.local state
- Some examples are: – current page in a
PageView – current progress of a complex animation – current selected tab in a BottomNavigationBar
- Other parts of the widget tree seldom need to access this kind of state. There is no need to serialize it, and it doesn’t change in complex ways.
- In other words, there is no need to use state management techniques (ScopedModel, Redux, etc.) on this kind of state. All you need is a
StatefulWidget.
