Convert Microsoft Word to PDF in Flutter

ivanov.ap84 · October 9, 2021, 4:11pm

Hi. I have flutter code like:
void convertToPdf(String file,String name,String ext)async{
var configuration = Configuration(’, ‘’);
var wordsApi = WordsApi(configuration);

var localFileContent = await (File(file).readAsBytes());
var uploadRequest = UploadFileRequest(ByteData.view(localFileContent.buffer), 'fileStoredInCloud.docx');

final res = await wordsApi.uploadFile(uploadRequest);

var saveOptionsData = SaveOptionsData()
  ..saveFormat = 'pdf'
  ..fileName = '${authInstance.currentUser.uid}/${name}.pdf';
var saveAsRequest = SaveAsRequest('fileStoredInCloud.docx', saveOptionsData);
final res2 = await wordsApi.saveAs(saveAsRequest);
print('111${res2.saveResult.destDocument.href}');
print('111${res.uploaded}');

}

But how i can get converted pdf file from your server with flutter SDK. And how i can get total pages of converted PDF file?

Please check the following download file unit test from GitHub. It will help you to accomplish the task.

github.com

aspose-words-cloud/aspose-words-cloud-dart/blob/master/test/storage/file_tests.dart#L104


      
            await context.uploadFile(localFile, remoteDataFolder + '/' + remoteFileName);

          

            final request = DeleteFileRequest(

              remoteDataFolder + '/' + remoteFileName

            );

          

            await context.getApi().deleteFile(request);

          }

          

          /// Test for download file.

          Future<void> testDownloadFile() async

          {

            final remoteFileName = 'TestDownloadFile.docx';

            await context.uploadFile(localFile, remoteDataFolder + '/' + remoteFileName);

          

            final request = DownloadFileRequest(

              remoteDataFolder + '/' + remoteFileName

            );

          

            await context.getApi().downloadFile(request);

          }

You need to use GetDocumentStatistics API method and need to read PageCount property from response for the purpose.

github.com

aspose-words-cloud/aspose-words-cloud-dart/blob/master/test/document/document_statistics_tests.dart#L46


      
          final TestContext context;

          late String remoteDataFolder;

          late String localFile;

          

          DocumentStatisticsTests(this.context) {

            remoteDataFolder = context.remoteBaseTestDataFolder + '/DocumentActions/Statistics';

            localFile = 'Common/test_multi_pages.docx';

          }

          

          /// Test for document classification.

          Future<void> testGetDocumentStatistics() async

          {

            final remoteFileName = 'TestGetDocumentStatistics.docx';

            await context.uploadFile(localFile, remoteDataFolder + '/' + remoteFileName);

          

            final request = GetDocumentStatisticsRequest(

              remoteFileName,

              folder: remoteDataFolder

            );

          

            final result = await context.getApi().getDocumentStatistics(request);

Thanks for sharing this! The sample code really helped—got the Word-to-PDF conversion working in my Flutter app without much hassle. Super useful for anyone stuck on the setup part.
