# build-windows.ps1
#
# Build RustDesk 1.4.7 (our fork) on Windows 11.
# Run from an "x64 Native Tools Command Prompt for VS 2022" PowerShell window.
#
# What it does:
#   1. flutter pub get
#   2. flutter_rust_bridge_codegen (regenerates generated_bridge.dart)
#      — REMEMBER: hand-patch the 3 sites in generated_bridge.dart!
#   3. cargo build --release
#   4. flutter build windows --release
#   5. Optional: signtool sign the .exe
#   6. Zip up the Release/ folder
#
# Re-run this script any time: incremental builds are fast (~30 sec for
# Flutter, ~1 min for Rust when nothing changed).
