bug: Collision during build when multiple flutter based packages are added in home.packages

Issue description

When more than one flutter based packages are added through home.packages, build fails with collision between files from the packages. This does not happen when the same packages are added through users.users.<name>.packages or environment.systemPackages

example with home.packages = [ pkgs.localsend pkgs.fluffychat ]

I hit that bug with localsend and rustdesk-flutter .... found a workaround in the discource link above. Any ideas if there will be a right solution available instead of ugly kludge ?

[gungun974]

I'm got the same Issue with localsend and my WIP flutter based music player.

I see there was some idea to temporary fix it but right now since I'm the only user / developer of my App.

I cheat by moving in my postFixup the /app to a sub directory, everything seem to works fine with the moving path (note I recreate the wrap).

But I still think this issue is annoying since custom sub directory in /app is not the norm of buildFlutterApplication
