I think your question does not show how much you have researched before and where/why you are stuck. Implementing dark mode is a well-known problem that has been solved many times before, and SO makes a point to not repeatedly answer the same questions - so judging only by the context you provided I assume it was closed as a duplicate or as low-quality.
