1Fix for macOS build issue in Flutter >= 3.35
2
3Since version 3.35, the behavior of macos_assemble.sh and xcode_backend.sh
4is almost identical. This caused the same error for macOS that previously
5occurred for iOS.
6
7Derived from the iOS patch: ./fix-ios-build-xcode-backend-sh.patch
8
9Example error:
10```
11$ flutter run -d macos
12Launching lib/main.dart on macOS in debug mode...
13Target debug_unpack_macos failed: Error: Flutter failed to create a directory at "/<nix-store>/XXXX-flutter-3.35.1-unwrapped/bin/cache/artifacts".
14Please ensure that the SDK and/or project is installed in a location that has read/write permissions for the current user.
15Failed to copy Flutter framework.
