如何在扑动转换docx到pdf文件?

Question

我正试图将我用docx_template库制作的docx文件:^0.3.3到PDF，我尝试过使用库来做到这一点。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');

Answer 1

使用此包或任何支持以字节形式输入的包

https://pub.dev/packages/syncfusion_flutter_pdf

您可以将doc转换为字节并生成如下所示的pdf

//Load the existing docx document.
final PdfDocument document =
PdfDocument(inputBytes: File('input.docx').readAsBytesSync());

//Save the document.
File('yourFileName.pdf').writeAsBytes(await document.save());
//Dispose the document.
document.dispose();
