- Yesterday, I talked about how upload an image from Flutter-webapp
- Today, I'm going talk about How to add an image to Hive Post on a Flutter Android/ iOS App.
- Note, this post is a part solution. I'll publish another part when it's working, most probably tomorrow.
Adding an image on Hive Post
- https://developers.hive.io/services/imageHoster.html - Here the piece of code for uploading the image when you have the PostingKey.
- I found some related code but not exact code to match my need - upload image with @HiveKeychain, @hiveauth
- In this article, I'll illustrate how to upload an image even with plain javascript inside html page.
Objective: Use Flutter as front-end & Upload an image using HTML & vanilla JS
We'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.
Reference #1: https://gitlab.syncad.com/hive/condenser/-/blob/develop/src/app/redux/UserSaga.js#L861
Reference #2: https://developers.hive.io/services/imageHoster.html
Step 1: Getting the Buffer
<body>
// this one to get the access to Buffer
<script src="https://bundle.run/[email protected]"></script>
Step 2. Getting Base64 of an image.
- We'll implement
image_pickeron the Flutter side. - Flutter side code will generate base64 of selected image.
- Flutter side code will supply base64, file name to javascript side.
Step 3: Processing based on file name
- based on file name supplied, we'll define the upload type.
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";
}
}
Step 4. Creating File from Binary
- Following code snippet will generate a file from given binary & file path.
- It uses above defined function as well.
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;
}
Step 5. Base64 to Binary & Binary to Buffer
- We'll call following function from flutter side.
- In this, we'll be supplying base64 encoded image
- This base64 encoded image will be converted to file (binary)
- From that binary, we'll generate buffer
- This buffer, we'll use to create signature
- And created file, we'll use to upload it on Hive
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.
}
That's it?
- NO NO. Not yet. Let's wait for next post.
- In next post, I'll connect the dots & add a short demo video to show it working.
- I'm not the HTML or Javascript Guy.
- I like iOS App Development - Swift & I like Flutter.
- For me, it really took good amount of time to not only figure it out but to put pieces together to make it work.
- So, take a moment of appreciation, please don't forget to upvote the content or vote me as Hive Witness
