@salim-lachdhaf I'm getting a similar issue with dropdown_search: 5.0.2.

I have a situation where I insert my own OverlayEntry for a custom overlay. In that overlay I use a DropdownSearch<T>() with menu as the presentation type.

I can put DropdownSearch in the overlay, but opening it yields a wrong position for its overlay. It is also below my own overlay and not on top of it. When I try to close the DropdownSearch overlay, I get

══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════
The following assertion was thrown while finalizing the widget tree:
Duplicate GlobalKey detected in widget tree.
The following GlobalKey was specified multiple times in the widget tree. This will lead to parts of
the widget tree being truncated unexpectedly, because the second time a key is seen, the previous
instance is moved to the new location. The key was:
- [LabeledGlobalKey<SelectionWidgetState<User>>#a483d]
This was determined by noticing that after the widget with the above global key was moved out of its
previous parent, that previous parent never updated during this frame, meaning that it either did
not update at all or updated before the widget was moved, in either case implying that it still
thinks that it should have a child with that global key.
The specific parent that did not update after having one or more children forcibly removed due to
GlobalKey reparenting is:
- DefaultTextStyle(debugLabel: (englishLike bodyMedium 2014).merge((blackRedwoodCity
bodyMedium).apply), inherit: false, color: Color(0xdd000000), family: Prompt, size: 14.0, weight:
400, baseline: alphabetic, decoration: TextDecoration.none, softWrap: wrapping at box width,
overflow: clip)
A GlobalKey can only be specified on one widget at a time in the widget tree.

When the exception was thrown, this was the stack:

Since there is no inline presentation type that does not create its own overlay, I'm going to have to write my own widget (which isn't really a big deal)

thank you for reporting that, could you past an complete reproductible code to analyse the issue ?
