v80 appears to not highlight widget tree in editor

[dropik]

I don't know if this is a feature deprecation, since I can't find any mentioning on this in changelog, or if it is actually a bug. But I would say this was a really nice feature to have, so for me it seems like a bug.

So what actually happens is that in the newer version v80 of the plugin, the editor of Android Studio unfortunately does not show anymore that tree highlighting of nested widgets. In previous version v79 it used to work like this:

And in the new version it does not show this highlighting anymore and appears to fallback to default indentation highlight:

Steps to Reproduce

• Install Flutter plugin v80.0.1
• Make sure feature does not work
• Downgrade to plugin v79.0.2
• Observe the feature works again
