我正在尝试转换我用docx_template库创建的docx文件：^0.3.3到PDF，我已经尝试过使用库来做到这一点。Whit SyncFusion我有这个：
//Get external storage directory
final directory = await getApplicationDocumentsDirectory();
//Get directory path
String path = directory.path;
final of = File('$path/Engranes Rectos Sistema Ingles.docx');
if (d != null) await of.writeAsBytes(d);
Directory directory2 = (await getApplicationDocumentsDirectory());
String path2 = directory2.path;
final PdfDocument document = PdfDocument(
inputBytes: File('$path/Engranes Rectos Sistema Ingles.docx')
.readAsBytesSync());
//Save the document.
File file = File('$path/Engranes Rectos Sistema Ingles.pdf');
await file.writeAsBytes(await document.save(), flush: true);
//Dispose the document.
document.dispose();
OpenFile.open('$path/Engranes Rectos Sistema Ingles.pdf');
