How to use both Android and IOS simulator simultaneously to test my flutter app during development?

Issue

I was wondering if I can set up and use both Android and iOS simulators simultaneously when I develop my flutter app? It makes things easier and allows me to catch platform-specific bugs earlier.

Is this possible?

Solution

Yes. If you have both iOs and Android emulators running, you can use the command flutter run -d all to launch on both devices. If you want to launch on one device with both open, you will have to specify which one by telling it the device id, like flutter run -d emulator-5554.

While developing I like to have the iOs emulator open for debugging in case I want to jump in and see the value of a particular variable at a particular moment, and the android emulator for running the app / designing / iterating.
