consider checking for flutter framework updates

[devoncarew]

We should consider checking for flutter framework updates as part of the IntelliJ 'check for updates' action.

FWIW I did some poking around (and confirmed w/ Alex) and there doesn't seem to be a way to easily hook into the update check. The best angle is probably to do our own update check the way we do in the Dart Plugin.

Popping up, I do think this would be very handy since so many of our exchanges with folks begin with "could you update you SDK and try again?" I'll look a little deeper.

@devoncarew feel free to re-assign if you're already tackling. 👍

Cool, thanks for looking into it. I think android studio has custom behavior here, but they may replace the action completely (which isn't something we're likely to want to do).

With recent changes and going forward, the Flutter IJ plugin will be required to work with recent SDK versions, see recent changelog for details.
