Implementation

@override
Future<pw.Widget> generateWidget({
  double? maxWidth,
  double? maxHeight,
}) async {
  final Document? document = RichTextParser().parseDelta(this.document);
  if(document == null){
    throw StateError('The Delta passed is not valid to be parsed. Please, first ensure the Delta to have not empty content.');
  }
  final List<pw.Widget> widgets = await blockGenerators(document);
  final pw.Widget content = pw.Column(
    crossAxisAlignment: pw.CrossAxisAlignment.start,
    children: widgets,
  );
  pw.Container widget = pw.Container(
    width: maxWidth,
    height: maxHeight,
    child: content,
