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 Android Studio 2023.3.1 build AI-233.14808.21.2331.11709847
• Install Flutter plugin v80.0.1
• Make sure feature does not work
• Downgrade to plugin v79.0.2
• Observe the feature works again

Update.

On another pc this does not work also on version v79... So it must be a bug. But now I have no clue on what might be causing the problem: the plugin, the Android Studio, the flutter version, or may be an evil combination of versions of all.

This is the flutter doctor from the second machine:

And from logs on this machine I see these warnings that would might have something to do with the flutter I think:

Update n.2

Was trying to experiment with different versions of flutter and different versions of plugin, and now I'm completely lost.

So on the second machine v79 appears to work with flutter 3.16.0, same as on the first machine, but not with 3.22.0. And v80 does not appear to work with any version, that I've tried on both machines, which were:
3.7.12
3.10.6
3.13.9
3.16.0 - 3.16.5
3.19.0
3.22.0

Also I've noticed that for v80 the outline tab does work with some flutter versions, while with others it doesn't show anything. Which brought me to this issue #6253, and some sort of version mismatch was causing the problem as well there. But it is quite old, and for me the tree highlighting in v80 does not work with any of the tried versions, which is quite weird that it does not work with that wide range of versions...

Which flutter sdk version should be supported by the plugin v80?

[ganeshbabugb]

I too got the same issue in my machine.

[helin24]

Thanks for the detailed info. I've looked at this in the past so I'll see if I can fix this for an upcoming release.

Awesome news, thank you!

[Nacho-Larreta]

Yep, and flutter outline is not working too if you make a fresh install with the latest version of dart, flutter plugin and intellij. To make it work again you have to downgrade to Dart plugin 241.15845 and Flutter Plugin 78.5.1
