EditingValueBuilder<T> class
Builds builder with value, recreating its subtree (its state is lost) each time value changes, except while an element is being edited in it (see EditingScope): the displayed value is then kept, and updated to the latest value when editing ends. Values are compared with ==: a subtree won't be recreated after a save if the new value equals the previous one. Inside a FetchBuilder or EventFetchBuilder, keep FetcherConfig.fadeOnDataChange to false (default): otherwise this widget is recreated on each data and can't keep the displayed value. Loading and error states also replace this widget (e.g. stream error, refresh with clearDataFirst).
