Description

Hello, is there any way to detect light or dark mode on the system an application is running on to change themes respectively?

After looking for a while I can't find any mention of it in Druid, and no Druid example seems to adhere to the dark/light mode setting (at least on MacOS) despite its theme containing keys for dark and light colors?

Should I just rely on the dark-light crate for now and check periodically?

Research direction
The issue requests dark/light mode detection for Druid. The user references Druid's theme constants for dark and light colors and suggests using the dark light crate. To implement, investigate platform specific APIs (e.g., macOS appearance change notifications) and how to integrate them into Druid's existing theme system. Look at druid/src/theme.rs for theme constants and consider adding an event or method to query the system theme. The dark light crate (https://crates.io/crates/dark light) could serve as a starting point. No linked PRs or assignees, so this is open for contribution.
