Export Image data of QR-Code

Hi, I'd like to download a QR code to the device of the user. For this, I need the image data. Now my question: How to get a PNG image out of an QrImageView()?

you can find an example of how to get the image bytes in test/painter_test.dart

An export to svg would be cool as well

It's a workable but not flexible option. With QrPainter.toImageData we can't customize paddings, background and more. QrCode always draws with transparent background.

We are left to implement our own painter or other export option.

Also looking for out of the box export method. I think export its a must for this library !
