I changed the theme in jEdit global options to "FlatLaf Dark". It only resulted in part of the theme becoming dark. How do I fix this?

I found I have to change the colors under "Text Area" but the result is still bad. The colors used for syntax highlighting are not clearly distinguished in a dark background.

Is there some officially-supported dark theme?

You can change the colors from syntax highlighting

As far I know, there is no plugin that would set all of them at once

I invert the whole display.

If you use the latest release (Isabelle 2025-1-RC) then you just need to change it in JEdit -> Appearance -> Swing Look & Feel and restart Isabelle once. In the new release we have a official dark mode

Where do I get Isabelle-2025-1-RC? In the Isabelle page there is only Isabelle 2025.
