Open project view for flutter projects

[helin24]

This shows the project view for flutter projects on first open:

There's a problem with this fix though, in this scenario:

1. Open the flutter project (this will open to the project view correctly)
2. Close the project
3. Open the project's Android subdirectory (this will open to the android view correctly)
4. Open the top-level flutter project again - this will open to the android view, which isn't what we want

So I don't even know if I want to commit this code, because it feels like we are trying to manipulate a mechanism that's already pretty complicated. Any opinions are welcome.

(mostly) Fixes 8556

This feels tricky and I'm with you completely in asking if we want to have bespoke special-case code like this in general. Here, it does seem like an improvement to the common case so maybe worth committing? If you feel that, I'd ask for you to add some notes to the implementation reflecting the limitation and maybe a link back to #8556 so we can replay this conversation easily down the road if needed.

Thanks for putting so much thought into this!

Thanks for the suggestions! I agree, it should be helpful for the majority of cases. When we have analytics, it would be nice to know how often users are opening the android subdirectory and using that workflow for editing native code.
