row method

Iterable<RenderBox> row(
  1. int y
)

Returns the list of RenderBox objects that are on the given row, in column order, starting with the first column.

This is a lazily-evaluated iterable.

Implementation

// The following uses sync* because it is public API documented to return a
// lazy iterable.
Iterable<RenderBox> row(int y) sync* {
  final int start = y * columns;
  final int end = (y + 1) * columns;
  for (int xy = start; xy < end; xy += 1) {
    final RenderBox? child = _children[xy];
    if (child != null) {
      yield child;
    }
  }
}
