base64Decode removes pages from a pdf in base64?-CodePudding

The

I get the response.data, and I use base64Decode to get the Uint8List, I save the file in the storage.

class FileSaverHelper { Future<String> save({required String filename, required Uint8List bytes}) async { final String tempDir = (await getTemporaryDirectory()).path; final filePath = "$tempDir/$filename"; await File(filePath).writeAsBytes(bytes); return filePath; } } class OpenFileHelper { final FileSaverHelper fileSaverHelper = Get.find(); Future<void> open({ required String filename, required Future<Uint8List> Function() onDownload }) async { final Uint8List bytes = await onDownload(); final filePath = await fileSaverHelper.save( filename: filename, bytes: bytes ); if(await File(filePath).exists()){ OpenFilex.open(filePath); } } }

When I open the PDF it has only the first page and when I test the base64 that the server sends in the site

Why after I use base64Decode(response.data), save the PDF to the storage, open it, it has only the first page but in the site the amount of pages is correct?

CodePudding user response：

I found the problem is with the GET request, since the base64 retrieve by the server only through flutter, the file is retrieved incomplete.
