TextSpan
buildTextSpan({
- required BuildContext context,

- bool? withComposing,
override

Implementation
@override
TextSpan buildTextSpan(
{required BuildContext context, TextStyle? style, bool? withComposing}) {
final children = <TextSpan>[];
final list = text.split("\n");
for (int k = 0; k < list.length; k++) {
final el = list[k];
final number = int.parse(el);
var textSpan = TextSpan(text: el, style: style);
if (lineNumberBuilder != null)
textSpan = lineNumberBuilder!(number, style);
children.add(textSpan);
if (k < list.length - 1) children.add(TextSpan(text: "\n"));
}
return TextSpan(children: children, style: style);
}
