PlutoGridStateManager is a ChangeNotifier.
You can add a listener and know it through the stateManager.

late PlutoGridStateManager stateManager;

dispose() {
  stateManager.removeListner(handler);
}

void handler() {
  // currentRow is null or PlutoRow.
  // stateManager.currentRow
}

PlutoGrid(
  onLoaded: (event) {
    stateManager = event.stateManager;
    stateManager.addListener(handler);
  }
);
