Conflicts of library for Reachability in iOS

[sawan07]

The iOS application never opens. When I tried to archive it I am getting the following error

Multiple commands produce '/Users/mdhasanrahman/Library/Developer/Xcode/DerivedData/Runner-fgzktmibyndpbgfkmsizqhgncvxe/Build/Intermediates.noindex/ArchiveIntermediates/Runner/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/Reachability.framework':

Same problem

Edit: Turned out to be a third-party library that was relying on the old connectivity package. Once discovering that and removing/updating the pubspec accordingly, I no longer seem to have that issue

Same problem, took me few hours to figure out
