Now I just want to learn if I use the flutter module and build the aar , how can I send function as prop in native android ?

This is not possible because you can send only serializable types

By default, AIDL supports the following data types:

• All primitive types in the Java programming language (such as int, long, char, boolean, and so on)
• Arrays of primitive types such as int[]
• String
• CharSequence
• List
  All elements in the List must be one of the supported data types in this list or one of the other AIDL-generated interfaces or parcelables you've declared. A List may optionally be used as a parameterized type class (for example, List). The actual concrete class that the other side receives is always an ArrayList, although the method is generated to use the List interface.
• Map .
  All elements in the Map must be one of the supported data types in this list or one of the other AIDL-generated interfaces or parcelables you've declared. Parameterized type maps, (such as those of the form Map<String,Integer>) are not supported. The actual concrete class that the other side receives is always a HashMap, although the method is generated to use the Map interface. Consider using a Bundle as an alternative to Map.

For more detailed information you can refer to the official AIDL documentation
