Future<void> main() async {

  // This will try to sequentially launch the given devices, running the given
  // function on each one.
  await emu.forEach([

    'iPhone 12 Pro',

  ])((device) async {
    // Create a screenshot helper.

    // Or you can run flutter drive, and send the output to stdout

    await stdout.addStream(process.stdout);
