[FIXED] Unable to run new flutter sample code in IntelliJ IDEA

Issue

I installed IntelliJ IDEA, downloaded both the flutter and dart plugins, Installed android studio and jdk . I opened configured IntelliJ IDEA to point at the android sdk and jdk.
I opened up IntelliJ IDEA and created new project->flutter. I clicked on build and got an error message.

I am using Ubuntu 16.04 64 bit system

I ran Flutter Doctor and confirmed that i got nothing new or missing installation. The message at debugger is as shown

The built-in library 'dart:ui' is not available on the stand-alone VM. 
library handler failed export 'dart:ui' show Locale
Process finished with exit code 254 Failed to connect to the VM observatory service: java.io.IOException: Failed to connect: ws://127.0.0.1:46579/ws Caused by: de.roderick.weberknecht.WebSocketException: error while creating socket to ws://127.0.0.1:46579/ws Caused by: java.net.ConnectException: Connection refused

Standard new flutter project code with output

Debugger output which i copy pasted

Solution

It sounds like IntelliJ is configured to run as a Dart command line app instead of a Flutter app. Edit configurations and remove any configurations that look like "Dart Command Line App". Then create a new one for a Flutter app.
