dispose abstract method

FutureOr<void> dispose()
inherited

Dispose this object and clean up its resources.

This method should be idempotent - calling it multiple times should be safe and not cause errors. After disposal, the object should not be used for any operations.

Returns: A Future that completes when cleanup is finished, or completes synchronously if no async operations are needed.

Implementation Guidelines:

  • Always check if already disposed before doing work
  • Clean up in reverse order of initialization when possible
  • Handle exceptions gracefully to prevent partial cleanup
  • Set disposed flag to prevent further use
