cellBuilder method

Implementation

  // get row and column indexes
  var rowIdx = rows.indexOf(context.row);
  var colIdx =
  map.containsKey(context.column) ? map[context.column]!.index : -1;

  if (rowIdx.isNegative || colIdx.isNegative) return const Text("");

  // get cell model
  TableRowCellModel? model = widget.model.getRowCellModel(rowIdx, colIdx);
  if (model == null) return const Text("");

  // return the view
  if (!views.containsKey(model)) {
    // build the view
    Widget view = RepaintBoundary(child: BoxView(model));

    // cache the view
    views[model] = view;
  }

  // we must wrap the cell in a listener to select the row on tap
  // this isn't necessarily required if the cell doesn't have a gesture detector, onclick, etc
  // without this, the onTap (select) is consumed by the child view
  var cell = Listener(
      child: views[model],
      onPointerDown: (_) => onTap(context.cell, context.rowIdx));

  // we override the key listener in order to enable input on
  // enterable fields

      child: cell,
