SwayzeCellsController<CellDataType extends SwayzeCellData> class

A ChangeNotifier that is in charge of managing the state of all cells in a table and to communicate state changes to its listeners.

There are two ways of modifying it state:

• From raw cells: Ideally for communicating changes from an external format of cells such as JSON. The changes should be made via putRawCells. The controller constructor also receives a iterable of raw cells. The cells will be parsed to CellDataType via cellParser.

• From parsed cells: Changes via parsed cells should be made via updateState.

cellsController.updateState((modifier) {
     modifier.putCell(
       TestCellData(
         position: const SwayzeCellPosition(column: 0, row: 0),
         value: 'some new cell',
       ),
     );
});

The parameter on the callback passed to updateState is a CellsModifier.

After each updateState, all listeners of SwayzeCellsController will be notified.
