How do you run the Flutter app on simulation?

There is an editor plugin for Android Studio, IntelliJ, or VS Code. However, I recommend to go for VS Code(Visual Studio Code).

Click Product -> Destination -> iOS Simulator -> Choose Device to run . Then build and execute Xcode project. Show activity on this post. On Mac, if you right click on the Simulator icon, you can select devices and it will open a new device.
