4 months ago Framework team: is it expected that a package bug could cause this error? It's not clear to me from the stack.

3 months ago I just encountered the same error using a regular Scaffold with GoRouter and SelectionArea. Are there any updates on this?

1 month ago It may has to do with the fact, that the same scaffold is stacked on top via the navigation, and the selection_area may confuses them (?). ~If I wrap the secondaryBody within its own SelectionArea, it doesn't throw an error.~ Edit: Still occurs from time to time.
Seems related to #114254
@helpisdev @sunenvidiado-nx @gabrielrf97 you may want to thumb up (+1) the original issue description to support pushing this issue. I think comments like this should be avoided: https://github.com/flutter/flutter/tree/master/docs/contributing/issue_hygiene#comments

1 month ago A theory: I adapted the example to better debug the thing.
AdaptiveScaffold stacked on top of each other.rootA and rootB from the root AdaptiveScaffold and subA and subB from the subpage are added to the SelectionArea tree.RenderFractionalTranslation#40372 NEEDS-LAYOUT NEEDS-PAINT, so these are the two selectable Texts from the root Scaffold: A and B.AdaptiveScaffold uses _SlotIds to layout the childs. ~I think these slot ids are not unique, if there are multiple AdaptiveScaffolds involved, so it just layouts the wrong child Text by chance. I can't really tell, why this is only the case, when both, the secondaryBody and the body are present.~ Edit: I might be wrong as the MultiChildLayoutDelegate._idToChild of _AdaptiveLayoutDelegate only exists in its own context.So it would be a flutter_adaptive_scaffold package issue. Can this be correct?
But in general it would be good to have better logging message, which widget is responsible for the error.

1 month ago I could reproduce it without flutter_adaptive_scaffold. The problem is, that the SelectableArea tries to compare the selectables (if there are more than 2), and then cannot determine the size of the ones of the root page, because they weren't even layouted.
