ConvertComputed<T, U> class abstract interface

Interface for type-converting computed signals.

ConvertComputed provides a way to create a computed signal that converts between different types while maintaining reactivity. It acts as a bridge between signals of different types, automatically handling the conversion in both directions.

Example:

final count = Signal(0);
ConvertComputed<String, int> textCount = ConvertComputed(
  count,
  decode: (int value) => value.toString(),
  encode: (String value) => int.parse(value),
);

print(textCount.value); // "0"
textCount.value = "42"; // Updates count to 42
