# Rows and Cells

### Default properties of rows

Rows should be passed as a `List<PlutoRow>` type to the `rows` property when creating a `PlutoGrid`.
It can also be passed as an empty list.

```dart
final List<PlutoRow> rows = [
  PlutoRow(
    cells: {
      'id': PlutoCell(value: 'user1'),
      'name': PlutoCell(value: 'Mike'),
      'age': PlutoCell(value: 20),
      'role': PlutoCell(value: 'Programmer'),
      'joined': PlutoCell(value: '2021-01-01'),
      'working_time': PlutoCell(value: '09:00'),
    },
  ),
];

Widget build(BuildContext context) {
  return Scaffold(
    body: Container(
      padding: const EdgeInsets.all(15),
      child: PlutoGrid(
        columns: columns,
        rows: rows,
      ),
    ),
  );
}
```

`cells` should be set to `Map<String, PlutoCell>` type with the `PlutoColumn.field` value set when creating `columns` as a key.

```dart
PlutoRow(checked: true);
```
The `checked` property is whether the checkbox is checked when `PlutoColumn.enableRowChecked` is set to `true`.
This value can be set at startup, and the value can be changed during runtime during grid operation.

```dart
PlutoRow(sortIdx: 0);
```
The `sortIdx` value indicates the first sort state of the row. When creating a grid, this value is automatically set according to the list order. If this value is set, this value is not automatically set when the grid is created.
This value is used to return to the original sort state when the sort state of rows is changed.


### Default properties of cells

Cells should be set to match the value of `PlutoColumn.field` when creating `PlutoRow`.  
`PlutoCell.value` must be set to a value that matches `PlutoColumn.type`. (text, number, date, etc.)  
If `PlutoColumn.type` is a type with a format such as number or date, the value of `PlutoCell.value` can be changed according to the format. (if `PlutoColumn.applyFormatterInEditing` value is set to `true`)  

```dart
PlutoRow(
  cells: {
    'id': PlutoCell(value: 'user1'),
    'name': PlutoCell(value: 'Mike'),
    'age': PlutoCell(value: 20),
    'role': PlutoCell(value: 'Programmer'),
    'joined': PlutoCell(value: '2021-01-01'),
    'working_time': PlutoCell(value: '09:00'),
  },
),
```
