design: 'material' causes app to crash

[nick-michael]

Bug report

Summary

Setting the design property to material causes the app to crash upon opening the date picker. Using Expo v53, datetimepicker v8.4.1 Included the @react-native-community/datetimepicker plugin both with no config and with some basic theming which works for the default picker. Running on an Expo development build.

Crash details:

java.lang.IllegalArgumentException: com.google.android.material.datepicker.MaterialDatePicker requires a value for the {bundle-identifier}:attr/materialCalendarTheme attribute to be set in your app theme. You can either set the attribute in your theme or update your theme to inherit from Theme.MaterialComponents (or a descendant).
