Is there a way to make this theme aware to fix #12577?

[marcelwgn]

I think, the only option would be to listen to theme changes and based on that reapply the background. Unfortunately, there is no code behind way to create a ThemeResouce binding (at none that I am aware of).

[yaira2]

Is it worth adding logic for that or should we leave as is since restarting the app will use the correct theme?

[marcelwgn]

Kinda depends on how urgent a fix is in your opinion. On App startup, the theme should match OS theme however if you change it during runtime, we might not know it. Given we use this.Resources the layout might have picked up the OS theme quite late in the lifecycle though

[yaira2]

We've only had one bug report so it's not the highest priority, if it's a simple fix I guess we should move forward but otherwise it's not worth it if it requires a complex workaround.

[marcelwgn]

I think it's not too hard, we would probably only need an event listener for the actual theme changed event. I'll add a comment to the issue in case anyone else wants to pick it up (and make it easier for newcomers to contribute)

Thanks!
