VoidCallbackIntent: undefined_method error since last commit

[robkri]

Since this commit, I get an "undefined_method" error in tree_view.dart (on lines 690 through 710) for VoidCallbackIntent which is - to my understanding - a part of Flutter's widget package.

Now I don't know where the error is coming from: I'm using VS Code on Win10, and there where similar issues before, where a class suddenly didn't get recognized anymore. Usually restarting VS Code or calling flutter pub get fixed these things, but now it doesn't seem to help.

To make sure, this isn't an issue with my fork, I cloned the original repo again. Here I have the same problem.

Any ideas?

It was my mistake: My flutter version wasn't up to date...

After upgrading to 3.3 the problem was solved.

I had the same problem. I'll update and test it tomorrow. Thank you.
