I am trying to export a QR code with an embedded image but I am not able to do that because it doesn't accept any type of image. I have tried literally every type of image possible still it just won't accept. What does it want?

Error:

My Code:

final painter = QrPainter.withQr(
        qr: qrCode!,
        color: const Color(0xFF000000),
        gapless: true,
        embeddedImageStyle: null,
        embeddedImage: Image(image: null,)
      );

Use AssetImage or NetworkImage.

Answer 2 · 2022-07-05T04:28:36.000Z

Use AssetImage or NetworkImage.

Already tried, they give the same error.

I know I have to enter image URL in NetworkImage, I just did for testing and to show you.

Oh you're using QrPainter, not QrImageView. Is that intentional?

Answer 8 · 2022-07-05T06:03:50.000Z

QrPainter expects a type of Image from dart:ui, not flutter/widgets.

Yes, I need an Embedded image when exporting the QR Code.

QrPainter expects a type of Image from dart:ui, not flutter/widgets.

So, what should I do to give it an Embedded image when exporting the QR ?
