cellSpan property

set cellSpan (FitGridCellSpanResolver? value)

How many columns each cell covers. Null means every cell covers one.

Implementation

set cellSpan(FitGridCellSpanResolver? value) {
  if (_cellSpan == value) return;
  final had = _cellSpan != null;
  _cellSpan = value;
  markNeedsPaint();
  if (had != (value != null)) markNeedsSemanticsUpdate();
}
