Thank you for sharing the code. I will try to replicate the issue.
Okay Thank you for help ,
and Can we connect on call so i can explain you properly
I’m afraid we only provide support here on the forum.
Ok no problam
did you got any solution or it’s helpful if you can connet with me any technical person
Once we come up with a solution, I will reach you.
Hi @Jaimin.fd1 , we suggest you use our SDK package for DART.
Package: aspose_words_cloud | Dart package
Sources: GitHub - aspose-words-cloud/aspose-words-cloud-dart
Our SDK is a REST API wrapper for our cloud service for fast, convenient and typed access to REST API operations without having to thinking about a structure of HTTP requests.
For example, the code for converting a document to a pdf using SDK will look like this:
final creds = Configuration('YOUR_CLIENT_ID', 'YOUR_CLIENT_SECRET');
final api = WordsApi(creds);
final request = ConvertDocumentRequest(requestDocument, 'pdf');
final response = await api.convertDocument(request);
i still can not got it solution.
i want a create doc file viewer in flutter using aspose.doc so can you share me with hole code ?
Your code converts the doc file to a PDF in the sample you shared above, and my colleague’s code does the same but uses SDK, so you don’t need to handle authorization, etc.
Can you share me hole code please
What do you mean by whole code? The shared code is already complete and has been converted to PDF. How you handle PDF is out of the scope of our SDK.
give me doc viewer code which i can use to view document
I can help you only with Aspose Words Cloud API-related questions. If you have any questions regarding this matter, feel free to ask.
I want to use Aspose.Word to Convert Doc file into HTML so how can i do that ?
As we suggested before - please use our Dart SDK aspose_words_cloud | Dart package
aspose-words-cloud-dart/test/document/convert_document_tests.dart at e43079a237c4a4cc3359a6a8dca0353b809e2a33 · aspose-words-cloud/aspose-words-cloud-dart · GitHub here you can find an example of how to convert document, you just need to change ‘pdf’ to ‘HTML’ in the request parameter.
