map a List of Streams of different types to Array of Arrays of corresponding types

In flutter, I am trying to take in an Array of streams of different types, handle the listening and dispose myself and turn them into nested providers.

A simpler description of this problem would be:
1. Start with n Lists of different types
2. Convert them into a List of Streams of different types
3. Map the List of streams of different types back into a List of Lists of corresponding types.
