The grid uses ChangeNotifier to manage its state. That's the PlutoStateManager. The widget receives it and reads the state, or registers an addListener to detect state changes. The addListener callback detects any state change, and when the widget needs state change, it executes setState to reflect the state change. This is an explanation of the simple operation. If you have any further explanations, please ask me and I will sincerely respond. And, the GetX you mentioned looks very good. I'll take a closer look and try to apply it. Thanks again for the introduction and comments of the good package. — You are receiving this because you authored the thread.

This is not in PlutoGrid, but I plan to work on a new project called PlutoInputPanel (tentative name). This hasn't started yet. I don't know if this will be your reference right away, but I made the structure simple. However, the code below was written in scratch state without the help of IDE's Auto-complete. Because of this, there may be problems with grammatical errors or referring to missing properties. class PanelRow extends StatefulWidget { final Handler handler; final rowIdx; PanelRow(this.handler, this.rowIdx); @OverRide _PanelRowState createState() => _PanelRowState(); } class _PanelRowState extends State<PanelRow> { final FocusNode focusNode = FocusNode(); @OverRide Widget build(BuildContext context) { if (widget.handler.currentRowIdx == rowIdx) { FocusScope.of(ctx).requestFocus(focusNode); } return Container( child: Row( children: [ TextField( focusNode: focusNode, ), FlatButton( onTap: () { handler.setCurrentRowIdx(widget.handler.currentRowIdx + 1); }, ), ], ), ); } } class Panel extends StatefulWidget { final rows; Panel(this.rows); @OverRide _PanelState createState() => _PanelState(); } class _PanelState extends State<Panel> { final Handler handler; final FocusNode focusNode; initState() { handler = Handler(); focusNode = FocusNode(onKey: handler.keyboardHandler); } @OverRide Widget build(BuildContext context) { return RawKeyboardListner( focusNode: focusNode, child: ListView.builder( itemCount: widget.rows.length, builder: (context, index) { return PanelRow( rowIdx: index, handler: handler, ); } ), ); } } class Handler extends ChangeNotifier { int currentRowIdx = 0; void setCurrentRowIdx(int idx) { currentRowIdx = idx; notifyListeners(); } bool keyboardHandler(FocusNode node, RawKeyEvent event) { // if key pressed arrowDown setCurrentRowIdx(currentRowIdx - 1); // if key pressed arrowUp setCurrentRowIdx(currentRowIdx + 1); } } — You are receiving this because you authored the thread.
