Add nullable annotations to generated output

[Anixias]

I noticed that in a project with nullable reference types enabled, no ? are generated on properties. This has resulted in me running into a few null reference exception crashes because I expected nullable warnings. Am I missing a specific setting to enable them or are they just not implemented?

Yeah, SourceGenerators doesn't use NRT, though it shouldn't stop you from using it in your project. Since child nodes don't exist until _Ready(), everything would need to be marked as nullable anyway.

Is that ok or does it cause a problem?

I am able to use it just fine, I just keep running into null-related crashes because I forget to access with ?. due to not using NRT. If it's not a bug no worries; I'd like to see it supported but not a huge deal otherwise.

Ok, great. I'll look at adding NRT annotations to generated output in the next release.
