# Package the Windows release as a self-contained distributable zip (#96).
#
# Flutter's Windows build is NOT self-contained — it depends on the MSVC runtime
# (msvcp140.dll / vcruntime140*.dll), which a clean machine may not have, so the
# exe fails to launch. This bundles those redistributable DLLs into the zip.
#
# Run AFTER `flutter build windows --release`:
#   & C:\Dev\flutter-meshcore\bin\dart.bat   # (not needed)
#   pwsh -File scripts/package-windows.ps1
