How to export the generated QR

[svprdga]

In the README it says: Export to image data to save to file or use in memory

I want to export the image to memory in order to be able to share it, in the README it doesn't say how to do it.

How can I export the generated QR?

The author made this article available to Medium members only.

I also need help with this, and I'd prefer not to have to subscribe to Medium to know how to do it.

Because the article is not freely available, and I was not able to find this documented elsewhere: You need to create a QrPainter object and call .toImageData on it.

The one liner I will be using to get Uint8List is as follows:

Uint8List? qrBytes = (await QrPainter(data: data, version: QrVersions.auto).toImageData(2048))?.buffer.asUint8List();

Is a premium article, is there an unlocked or better version of it?
