[kamilzych]

Steps to Reproduce

1. Update IntelliJ IDEA to 2018.3 EAP
2. Open a Flutter project
3. There's no support for Flutter in the IDE. If you go to "Plugins" settings you'll see it says that Flutter plugin is not compatible with this version of IntelliJ.

BTW. Although flutter doctor says that the Dart plugin is not installed, it's not true - it is.
I'm still able to develop the app, I have syntax highlighting, documentation pop-up and everything I need. I can run the app using CLI as well. What is missing is just the integration that flutter-intellij plugin is providing.

You're right that the 2018.3 EAP is not in our product matrix yet. I'll do some investigating to see what would be involved in adding support.

Thanks for the report!
