Dup of #5796.

[jacob314]

I'm not sure this is a dupe. I have a local fix for https://github.com/flutter/flutter-intellij/issues/5796 but I doubt my fix would change anything for hot reload.

This happens when the plugin changes the value of a numeric color. You need to select a new color and have the code get updated. That does not happen for named colors, only numeric. I'm not exactly sure what goes wrong, but the the PSI tree contains at least one error node where the new color value occurs. I think it probably needs to update the PSI tree, which happens after the reload fails. Or maybe we need to do a more atomic update so the error node is not generated.
