Unable to run new flutter sample code in IntelliJ IDEA

Question

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 1

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.

Solution 2

Click the name of the test, and choose "Edit configurations" You'll (probably) notice that the run config is under 'dart' rather than 'flutter test'

Delete this one, create a new one (using the plus button) under 'Flutter Test' and choose / run this manually.

(Also, you need to have the tests in a folder called 'test' at the same level (e.g. as a sister to) the lib folder, and follow the naming convention '*_test.dart' for all tests.)

Happy coding!

So you create a new project every time?

@EyoelD This may not be the best option, but it worked for me, and this was when flutter was still in beta.

Searching for ages, and this was the answer... thanks!
