fitGridSemanticsNodeCount function

int fitGridSemanticsNodeCount({
  1. int index = 0,
})

How many accessibility nodes the grid is holding.

Assert on this for the same reason as fitGridPaintedCellCount: emitting a node per row of the dataset would undo virtualization from the one direction nobody watches.

Implementation

int fitGridSemanticsNodeCount({int index = 0}) =>
    fitGridSection(index: index).semanticsNodeCount;
