apply<T extends DataGridRow> method

@override DataGridState<T>? apply<T extends DataGridRow>(EventContext<T> context)

Apply this event's transformation to the state. Returns the new state, or null if no state change should occur. Can return a Future for async operations.

Implementation

@override
DataGridState<T>? apply<T extends DataGridRow>(EventContext<T> context) {
  if (!context.state.edit.isEditing) {
    return null;
  }

  final cellId = context.state.edit.editingCellId!;
  final parts = cellId.split('_');
  final rowId = double.parse(parts[0]);
  final columnId = int.parse(parts[1]);
  final newValue = context.state.edit.editingValue;

  context.dispatchEvent(
    UpdateCellEvent(rowId: rowId, columnId: columnId, value: newValue),
  );

  return context.state.copyWith(edit: EditState.initial());
}
