03/29/2023, 2:47 PMGood morning guys! I have a question about compose migration that was raised here in the terms of a single source of truth. If you have a design system (XML) with colors tokens and typography already consolidated and you would initiate a Compose DS, what is the best strategy to maintain the single source of truth pattern in this case? How to access color tokens and how to access typography? Thanks!

• General: https://developer.android.com/jetpack/compose/designsystems
• Example: https://developer.android.com/codelabs/jetpack-compose-theming#3
There is also an additional resource for covering “Migration” (staying on xml for the theming):

03/29/2023, 3:06 PMThanks, @Thomas Urbanitsch! But my question is more about having only one source of color tokens and typography (in XML, as we already have this) for both libraries: XML-based DS and Compose-based DS

03/29/2023, 3:16 PMYou want to use definitions for colors and typography written once (preferably using the xml you already have) in both XML Layouts and Compose Layouts, correct?

03/29/2023, 3:22 PMYes! Actually, use these definitions in both design systems (XML and Compose)

03/29/2023, 3:28 PMYeah, I saw and the AppCompat Theme Adapter appears to work fine, but I don't know in the case of typography 🤔
