I am migrating from AppCompat to MaterialComponents, and I would like to keep some widgets (like the Bottom Navigation Bar) AppCompat-themed. However, when I want to apply MaterialComponents theming to Buttons and TextFields, I must set my app theme to MaterialComponents.... and therefore all my widgets are MaterialComponents-themed. How can I make only some widgets MaterialComponents-themed ? I have been looking for an answer on StackOverflow but couldn't find anything.
