[Naveen Cherian]

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 ran Flutter Doctor and confirmed that i got no errors

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

Your setup looks good! I think IntelliJ is trying to run your app as if it was a command-line dart app, not a Flutter one. There are some settings in IntelliJ to allow you to manage your launch configs. I would:

• delete the dart command-line one
• create a flutter one for your app (or confirm that one exists)

Then, from the launch config drop-down, select the flutter launch config for your app and hit run.

There are some docs here: https://flutter.io/intellij-ide/#running-and-debugging, though they don't cover creating a launch config.
