For international readers, the question is if it is possible to generate a Bitmap right away instead of writing to a file first. I'll translate the answer at the end as well :)

Opa! Tem sim! Por coincidência eu estava implementando justamente um exemplo com isso em mente!

Dá uma olhada nesse exemplo aqui: https://github.com/g0dkar/qrcode-kotlin/blob/main/examples/android/src/main/java/io/github/g0dkar/qrcode/QRCodeData.kt#L11

Basicamente, o objeto que é retornado quando você chama QRCode(data).render(), internamente, já tem um Bitmap (no caso do Android) pronto e você consegue acessar diretamente ele chamando o método nativeImage()

Estou finalizando um app Android de exemplo bem simples que mantém uma lista de QRCodes e os gera dinamicamente, sem salvar arquivos nem nada :)

Hey! There is! As a coincidence I was implementing exactly an example with this in mind!

Take a look at this example here: https://github.com/g0dkar/qrcode-kotlin/blob/main/examples/android/src/main/java/io/github/g0dkar/qrcode/QRCodeData.kt#L11

Basically, the object that is returned when you call QRCode(data).render(), internally, holds a Bitmap (in the case of Android) and you can access it directly by calling the nativeImage() method.

I'm finishing a really simple example Android app that keeps a list of QRCodes and generates the images dynamically, without saving files or anything :)
