LGTM. I will leave it to you if this changes at all with cherry picks.

Lgtm!

I thought that the flutter plugin version requires a certain dart plugin version, and so it would be possible to control what dart plugin we have without an extra check (which gets confusing since we also have dart sdk checks elsewhere). I see in testing you have this scenario though - is this also going to occur for normal users?

Oh that would be great if that is the case! Do you know where we tie the flutter plugin version to the dart plugin version?

The files involved are gradle.properties and product-matrix.json, for example changed in https://github.com/flutter/flutter-intellij/pull/7462/files

But I know this can be tricky to update and make sure all the versions are correct. @jwren has more experience testing different build combinations.
