Running flutter on Mac with VS Code and iPhone16 Pro Simulator from XCode

My iPhone16 Pro simulator works and builds the flutter app. I'm running the terminal from VS Code and it recognizes the simulator and XCode. However, when I try to change a colour and do a hot reload, no change is registered on the simulator.Base flutter project with "purple" instead of "blue". The hot reload function is supposedly successful, so I don't know why I can't update my simulator everytime I update my main.dart file.
