sendFileMessage method

Future sendFileMessage({ required String phone, required WhatsappFileType fileType, required List<int> fileBytes, String? fileName, String? caption, String? mimetype, MessageId? replyMessageId, String? templateTitle, String? templateFooter, bool useTemplate = false, bool isViewOnce = false, bool audioAsPtt = false, List<MessageButtons>? buttons, })

send file messages using sendFileMessage make sure to send fileType , we can also pass optional mimeType replyMessageId will send a quote message to the given messageId add caption to attach a text with the file

Implementation

Future sendFileMessage({
required String phone,
required WhatsappFileType fileType,
required List<int> fileBytes,
String? fileName,
String? caption,
String? mimetype,
MessageId? replyMessageId,
String? templateTitle,
String? templateFooter,
bool useTemplate = false,
bool isViewOnce = false,
bool audioAsPtt = false,
List<MessageButtons>? buttons,
}) async {
String base64Image = base64Encode(fileBytes);
String mimeType = mimetype ?? getMimeType(fileType, fileName, fileBytes);
String fileData = "data:$mimeType;base64,$base64Image";

String fileTypeName = "image";
if (mimeType.split("/").length > 1) {
  fileTypeName = mimeType.split("/").first;
}

// Check for video file type
if (fileTypeName == "video") {
  fileTypeName = "video"; // Set the correct file type for videos
}

String? replyTextId = replyMessageId?.serialized;
String? buttonsText = buttons?.map((e) => e.toJson()).toList().toString();

String source = '''WPP.chat.sendFileMessage(${phone.phoneParse},${fileData.jsParse},{
  type: ${fileTypeName.jsParse},
  isPtt: ${audioAsPtt.jsParse},
  isViewOnce: ${isViewOnce.jsParse},
  filename: ${fileName.jsParse},
  caption: ${caption.jsParse},
  quotedMsg: ${replyTextId.jsParse},
  useTemplateButtons: ${useTemplate.jsParse},
  buttons:$buttonsText,
  title: ${templateTitle.jsParse},
  footer: ${templateFooter.jsParse}
});''';

var sendResult = await wpClient.evaluateJs(source);
WhatsappLogger.log("SendResult : $sendResult");
return sendResult;
}
