dispose method

void dispose()

Clean up all resources and stop syncing.

Call this when you're done with sync (e.g., on app shutdown or user logout). This method:

• Cancels all change listeners
• Disposes all sync helpers
• Closes the change event stream
• Clears internal state

Important: After calling dispose(), this RealmSync instance cannot be reused. Create a new instance if you need to sync again.

Example:

// On logout or app shutdown
realmSync.dispose();
realm.close();
socket.dispose();

Implementation

void dispose() {
  for (final sub in _subscriptions.values) {
    try {
      sub.cancel();
    } catch (_) {}
  }
  for (final helper in _helpers.values) {
    helper.dispose();
  }
  _subscriptions.clear();
  _helpers.clear();
  _controller.close();
  _started = false;
}
