CollectionToCollectionConverter class abstract

An abstract base class for converting between different types of Dart collections, with optional element type conversion.

This converter works by:

1. Checking if the source type matches the expected this.
2. Verifying that the target type is a supported collection type.
3. Converting each element if type information is available.

Supported target types include:

• List, Set, Iterable, Queue
• ArrayList, HashSet, LinkedQueue, LinkedList, LinkedStack, Stack
• col.LinkedHashSet, col.ListBase, col.SetBase, col.Queue

Example:

final service = ConversionService(); // Your implementation
final converter = ListToCollectionConverter(service);

final source = [1, 2, 3];
final result = converter.convert(
  source,
  Class.forType(List),
  Class.forType(Set),
);

print(result.runtimeType); // Set<int>

Subclasses specify the exact source type (e.g., List, Set) via _sourceDartType.
