feat: adds capability to export user qr-code into wallpaper

[akash19coder]

Fixes Issue

Closes #9115

Changes proposed

• Created a component called QRcodeWallpaper.js. We are using inline-style in the component instead of Tailwind CSS because the tailwind style to place the QR code and Biodrop logo at appropriate position(please refer screenshot attached in the screenshot section) was not reflecting in the corresponding image.

function QRcodeWallpaper({ BASE_URL, data }) {
  const fallbackImageSize = 120;

  return (
    <div style={{ marginTop: "50%", marginLeft: "16%" }}>
      <QRCodeSVG
        className="border border-white"
        value={`${BASE_URL}/${data.username}`}
        size={fallbackImageSize * 6}
      />
      <div style={{ marginLeft: "7rem", marginTop: "5rem" }}>
        <LogoWide width={512} />
      </div>
    </div>
  );
}

• The newly created component will be transformed into HTML String with the following function. The renderToString() function used below is coming from import { renderToString } from "react-dom/server";

const renderQRCodeWallpaperToString = (BASE_URL, data) => {
  const qrCodeElement = React.createElement(QRcodeWallpaper, {
    BASE_URL: BASE_URL,
    data: data,
  });

  const qrCodeString = renderToString(qrCodeElement);

  return qrCodeString;
};

• The HTML String is then converted into image using a library called html-to-image library on a button click that is added into UserProfile.js. On button click following function is executed

const downloadWallpaper = async () => {
    try {
      const qrCodeString = renderQRCodeWallpaperToString(BASE_URL, data);

      const container = document.createElement("div");
      container.innerHTML = qrCodeString;

      const dataUrl = await toPng(container, {
        cacheBust: false,
        backgroundColor: "#122640",
        width: 1080,
        height: 1920,
      });

      saveAs(dataUrl, `Biodrop-Wallpaper-${data.username}.png`);
    } catch (e) {
      console.error(e);
    }
  };
