FPopover({required FPopoverController controller, required ValueWidgetBuilder<

-
True if the follower will be selected as the initial focus when no other node in its scope is currently focused.
final
- controller → FPopoverController

final
- focusNode → FocusNode?
-

final
- followerAnchor → Alignment
-
The anchor of the follower to which the targetAnchor is aligned to.
final
