I’m trying to build my flutter 3.22.3 project in Xcode Version 15.4 (15F31d). I keep getting an error

No such module FlutterMacOS

I want to avoid editing the xcode ui directly apart from adding a run script for the runner and flutter assemble build targets. I have removed and recreated the macos directory but it didn’t help. Here is my run script for both runner and flutter assemble targets, largely written by chatGPT:

if [ ! -f "$INPUT_FILE" ]; then
  echo "Creating $INPUT_FILE..."
  echo "$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" > "$INPUT_FILE"
