Hey, this is great! Mod'ed it to automatically switch to dark theme on launch:
https://gist.github.com/jrapoport/be65c76e9f2cbabbd84f336d5bc1d902

p.s. I forked @PatHightree's package and fixed it up, but ultimately ran into errors loading it that way. I'm not super familiar with custom Unity packages and didn't have time to figure out the issue. I suspect it has something to do with when the package gets executed vs. a normal script and the state of the editor, but who knows.

Cool but it doesn't work very well for me.

At the first start the ui become completely black, on the second click instead they go to the dark theme.

Yeah, it seems that it has to go through a reload, which was why I mentioned in the comments "Note - Once I ran this, I had to hit play and then it took effect". You can try one of the repos that the other folks in the comments have made and see if that helps any.

No, it seems that the same thing happens to everyone.
I will try to work on it in the meantime I hope that someone will discover how to fix it because it is really useful.

Hopefully, soon it won't matter. When asked about the dark theme on twitter, Unity replied with this:
So hopefully that means what I think it means, lol.

And actually, this was just posted 6 hours ago, it looks like.

Ok, as I experiment with what we are waiting for and see what happens.
For the moment the important thing is not to remain blinded, it is already so hahaha

Hello there,
I'm trying to understand how to setup this script. I can't manage to get this one working.
Thanks

@TheBoje,
Once you've added the script to your Unity project, you should be able to activate the dark theme from the Unity menu bar. Go to the "Theme" dropdown and click "Init Dark." Hopefully this works for you!

Yes, in the root of your project explorer, if you don't have one, create a folder called "Editor", in there make a new script called DarkTheme.cs and then paste this code into it and have Unity refresh. Then the new menu item will appear in the menu bar.

Thanks both @lestinkemonke @instance-id , however I figured out a couple hours later and forgot about this post. Btw thanks for saving my eyes, I justed used it during the Global Gam Jam I took part in.

Hey you should replace InternalEditorUtility.RequestScriptReload(); with UnityEditor.EditorUtility! Since it is deprecated. :) Love this dark theme! 👍

If this is not working for you, just change InternalEditorUtility.RepaintAllViews(); in the script to InternalEditorUtility.SwitchSkinAndRepaintAllViews(); - and you should be fine

If this is not working for you, just change InternalEditorUtility.RepaintAllViews(); in the script to InternalEditorUtility.SwitchSkinAndRepaintAllViews(); - and you should be fine

Can't seem to get it working with Unity 2019.3.12f1
I adds the "Theme" menu option > Init Dark ... but it doesn't seem to do anything even after Play =(
Any tips?
