[pluto grid checked rows] #flutter

main.dart

stateManager.rows

//You can access rows in List type.
//However, if they are filtered, you can only access them.

stateManager.refRows.originalList

//Same as rows, but you can access all rows regardless of filtering or not.

//Every row has a cells property and this is a map.
//The field value specified in the column can be accessed with the key.

//Suppose you have a field called user_id.
//If you need to get the user_id values of all rows into a List, you can do as follows.

var user_ids = stateManager.refRows.originalList.map((e) => e.cells['user_id'].value.toString());
//If user_id is retrieved only from the currently displayed rows in the filtered state, it is as follows.

var user_ids = stateManager.rows.map((e) => e.cells['user_id'].value.toString());
var user_ids = stateManager.refRows.map((e) => e.cells['user_id'].value.toString());
//rows and refRows are the same. However, rows are just destructured.


//When creating a grid, register a callback function with addListener in the stateManager.

        columns: columns,
        rows: rows,

          event.stateManager.setSelectingMode(PlutoGridSelectingMode.row);

          stateManager = event.stateManager;

          stateManager.addListener(handleCheckedRow);
        },

//In the case of the selection column, values other than items are not changed.
//Currently, you can change the value in the following way.

stateManager.currentCell.value = '';
stateManager.notifyListeners();

//And changing the value is as follows.

// For force, the default is false. 
// This is when the mode of the grid is select, 
// only the row can be selected and the value cannot be modified. 
// In this case, the value can be forcibly modified.
stateManager.changeCellValue(stateManager.currentCell.key, null, force: true);
