onEmpty property

Widget? onEmpty
final

A widget to be displayed in the case that the internal document list is empty (or a collection is empty).

Note: Leaving this as null will create a fallback pattern of:

  1. If onEmpty is null, fallback to onData if it's not null.
  2. Otherwise, fallback to the fallbackWidget if it's not null.
  3. Or as last resort, fallback to a SizedBox.shrink() (essentialy blank space). Therefore, it's encouraged to handle this state althoguh it is optional.

Implementation

final Widget? onEmpty;
