Description
What is the bug?
Stuck on Query.queryAndVisit when trying to export/import on ios (DartWorker:BAD_ACCESS), but works fine on my mac.
Version Info:
flutter:
i test 3.24.3, 3.27.1 both have this error
object_box:
i test 4.0.3, 4.0.1 both have this error
ios:
18.1.1, 17.6.1 both have
macos: works fine with 15.0(m1pro-14inch)
Issue desc(export)
first is export, i click the FloatingActionButton and exec onPressed function, the it's sucked, see blow screenshot


and then i start another new instance, and click again, a error occur, see blow screenshot

i think it's because Query.queryAndVisit still in progress, and i kill it case It left some intermediate artifacts, leading to the second error, so the root cause was getting stuck at the first export executing during the query. (BAD_ACCESS)
Notice: The version of flutter_map I am using is a specific commit, not a release version, at fleaflet/flutter_map@182c4fc, but i don't think it's flutter_map issue, i think it's some wrong in objectBox, or flutter it self
Issue desc(import)
i test import function with lib's example app, i use this
i modify path_picker's file type to any ,or fmtc can't be choose(idk why), but it's not path_picker's problem, i don't use path_picker in my own app, just read in working path

then choose a fmtc file, exported by my mac, exported code same as screenshot 1 (onPressed logic in FloatingActionButton) (mac works fine)
and error occur:

I am providing as much information as possible, please let me know if more is required.
