I finished all the work and I can read the data normally in debug mode. But uploading to TestFlight I don't know where the downloaded data goes?
In debug mode, the data is in the Runner.app/OnDemandResources/com.xxx.FontsPack-xxxx.assetpack directory, but the TestFlight version does not have this directory, so I I can't read the data.
So where should I go to find the downloaded Tag resource file?
