Is your feature request related to a problem?

For the QR-code and information dialog we are currently parsing markdown to build the text. We can set the required RichText regiments directly without having to parse a markdown string each time.

Describe the solution you'd like to see.

Set RichText segments directly. Hopefully it means that the markdown parser is dead code eliminates leading to smaller binaries (not sure how tightly coupled it is in Fyne or how smart the Go compiler is there).

HI, is this issue available to be taken? Might need to explore first though, but I want to give it a try. Thanks!

[Jacalz]

It is indeed available to be taken. As long as no one is assigned it is fine. However, I haven't tested that it is better than parsing markdown.

[GalihFajar]

Appreciate it, could you help assign it to me?

I've submitted the PR here.

I've built the code on the arm64 and it indeeds reduce the binaries smaller for about 2.3%.

Thanks for looking at it. I've assigned you to the issue and will try to review the PR later today :)
