You can use whatsapp_share2 package like this:

sahreOnWhatsapp(String phoneNumber,Uint8List doc){
    final directory = (await getApplicationDocumentsDirectory()).path;
    final docPath = await File('$directory/share.pdf').create();
    await docPath.writeAsBytes(doc);

    if (imagePath.path.isNotEmpty) {
      await WhatsappShare.shareFile(
         text: 'Whatsapp share text',
         phone: phoneNumber,
         filePath: [docPath.path],
      );
    }
}
