}
final nodes = getNodesInSelection(selection);
for (final node in nodes) {
final delta = node.delta;
if (delta == null) {
continue;
}
final startIndex = node == nodes.first ? selection.startIndex : 0;
final endIndex = node == nodes.last ? selection.endIndex : delta.length;
res.add(delta.slice(startIndex, endIndex).toPlainText());
}
