Hello Hive Community Members,
Welcome to daily updates from 
@hiveauthWe'll have a web-view on the native app side.
Using this web-view we'll be able to execute javascript of our choice.
Flutter can talk to native-apps & native apps can execute these javascript.
With this, we don't have to re-invent the wheel & create libraries in dart/flutter.
With this approach, we utilise already developed javascript libraries & make the max out of it.
In today's post, I'll talk about the javascript code which we'll be adding
In next post, I'll talk about how to execute javascript functions from Flutter.

image_picker on the Flutter side. function _getFileTypeFromExtension(fileName) {
let extension = fileName.split(".").pop().toLowerCase();
switch (extension) {
case "jpg":
case "jpeg":
return "image/jpeg";
case "png":
return "image/png";
case "gif":
return "image/gif";
default:
return "image/jpeg";
}
}
function _createFileFromBinaryString(binaryString, filePath) {
let fileName = filePath.substring(filePath.lastIndexOf("/") + 1);
let fileType = _getFileTypeFromExtension(fileName);
let byteArray = new Uint8Array(binaryString.length);
for (let i = 0; i < binaryString.length; i++) {
byteArray[i] = binaryString.charCodeAt(i);
}
let blob = new Blob([byteArray], { type: fileType });
let file = new File([blob], fileName, { type: fileType });
return file;
}
async function uploadImage(id, accountName, binary, filePath) {
const binaryString = atob(binary);
var file = _createFileFromBinaryString(binaryString, filePath);
const content = window.buffer.Buffer.from(binaryString, "binary");
const prefix = window.buffer.Buffer.from("ImageSigningChallenge");
const buf = window.buffer.Buffer.concat([prefix, content]);
// need to work on now getting the buffer signed from HiveKeychain/HiveAuth using HAS.
