Open Source Angular Libraries: MatDataSource, MatDatepicker
Add MatDateFnsModule at @matheo/datepicker/date-fns
The MatLuxonDateModule is available at @matheo/datepicker/luxon.
You will need to have luxon installed in your application because it's not added as dependency.
The DateAdapter class, the DateUnit and MatDateFormats types, and also the NativeDateAdapter, NativeDateModule and MatNativeDateModule were moved to @matheo/datepicker/core. Update the imports and everything will run again. This subpackage is equivalent to @angular/material/core with the Time extensions.
