Flutter-intellij: IntelliJ opens example project without Flutter module

[jsiedentop]

When I open one of the flutter examples in IntelliJ (tested with hello_world, hello_service and gallery), the IDE loads the Dart module but no Flutter module.

In the _Modul Settings_ (_context menu on the root node in the project tree -> Open Module Settings_) Is one problem listed: "_Project hello_world: project SDK is not defined_". I did't find a way to activate the Flutter Module in the IDE.

1. There should be a a way, to activate Flutter Support in the IDE
2. The IDE should recognize, that the Flutter module needs to be loaded. Maybe update the Flutter plugin or add a _flutter.yaml_ file in the example projects.

Informations to reproduce the issue and a workaround to activate the Flutter support:

1. Get the hello_world example:

https://github.com/flutter/flutter/tree/b9bff6a912c62c9dae5eddbaef80927655b769d7/examples/hello_world

1. Open the example project in IntelliJ

2. Click on "_Get dependencies_" in the "_'Pub get' has not been run_" message

3. The following error appear:

Working dir: /Users/jonas/dart/hello_world
/Users/jonas/Library/flutter/bin/cache/dart-sdk/bin/pub get
Resolving dependencies...
The Flutter SDK is not available.
Depended on by:
- hello_services 
Process finished with exit code 69

1. Close IntelliJ and create the file _flutter.yaml_ with this content:

name: hello_world
uses-material-design: true

1. Restart IntelliJ with the hello_world example.

2. The message "_'hello_world' is not a Flutter module, devide debugging is not fully supported._" appear.

3. Click on _Change module type to Flutter and reload project_

4. Run the pub action _Get dependencies_ (Should work fine without error).

Flutter doctor output:

$ flutter doctor

1. Open the example project in IntelliJ

@jsiedentop, just to make sure: are these the steps you use for this?

1. Invoke File->Open... in IntelliJ
2. Browse to the path flutter/examples/hello_world
3. Click OK

[jsiedentop]

@mit-mit, this is correct.

Thanks @jsiedentop. To confirm, it looks like you're using IntelliJ IDEA Community Edition (version 2016.2.5)? I'm guessing your Dart and Flutter plugins are up to date?

[jsiedentop]

Yes, I'm using the IntelliJ IDEA Community Edition in Version 2016.2.5
Pugins Versions
Flutter: 0.1.5
Dart: 162.2485

@mit-mit offered in #471 a better workaround for opening the example projects with flutter support and without creating the flutter.yaml file manually:

1. Close any open projects you have in IJ with hello_services in them
2. Invoke File > New> Project... in IJ
3. Click Next on the Flutter SDK page
4. In the New Project screen, click the ... button next to Project location, and browse to the folder that has the hello_services project
5. Click Finish
6. Say yes when it asks if you want to override an existing .idea or .idl files

The last point 6. was not necessary, cause I wasn't ased.

We need to verify that we see a butter bar to make this project a flutter project (and we should commit the updated mete-data file).

Butterbar verified.

And the action works.

However it appears to be updating files in the .idea subdir and I don't think we want to commit those.

Will look a little more tomorrow. (Ideas welcome in the meantime, though!)

We've made a lot of progress on improving detection of projects that do not have Flutter modules but should. There still remain issues specific to the flow for hello_services which will involve some feature work.

(See #471.)

Moved to On-Deck. Next steps depend on creating and exploring the getting started user journey.

Closing in favor of #316 which addresses the issue of Flutter projects missing IDEA metadata.
