Tip:
  The code for your app is in lib/main.dart.
  For a high-level description of what each code block does,
  see the comments at the top of that file.

Run the app

Locate the VS Code status bar
(the blue bar at the bottom of the window):

Select a device from the Device Selector area.
For details, see Quickly switching between Flutter devices.
        
          
            If no device is available, and you want to use a device simulator,
click No Devices and click
Start iOS Simulator to launch a simulator.

            
               Warning:
  You might not see Start iOS Simulator option
  when you click No Devices in VS Code.
  If you’re on Mac, then you might have to run following command
