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) {
  final updatedColumns = context.state.columns.map((col) {
    if (col.id == columnId) {
      return col.copyWith(width: newWidth);
    }
    return col;
  }).toList();
  return context.state.copyWith(columns: updatedColumns);
}
