Library not compatible with flutter 3.16.0 - incorrect type definition

[lunakoan]

Description

This library cannot be used with flutter 3.16.0 as one of it's functions contains a method call that returns a future which is incorrectly assigned to a different type causing the compilation error.

Steps to reproduce

1. Install flutter
2. Use this library - I use DioAdapter like so: DioAdapter dioAdapter = DioAdapter(dio: myDioInstance); dioAdapter.onPost(...);
3. See error

../../../.pub-cache/hosted/pub.dev/http_mock_adapter-0.6.0/lib/src/mixins/request_handling.dart:32:42: Error: A value of type 'FutureOr<List<int>>' can't be assigned to a variable of type 'List<int>'.
 - 'List' is from 'dart:core'.
          bytes = options.requestEncoder!(data, options);

Expected behavior

Library can be used with no issues.

getting exactly same error on version 0.4.4, is there any workaround for older version? I currently use flutter 3.7.0 and cannot upgrade yet because some package conflicts
