How can I know if the Markdown View rendered over?

Is there some way to let the caller know when the Markdown view is completely loaded?

Hi @RHxW,

There is currently no API in MarkdownUI to do that. But, since the only thing that the Markdown view loads asynchronously are images, you could replace the image-loading system with your own and track when the images are done loading.

See the markdownImageProvider(_:) and markdownInlineImageProvider(_:) modifiers.

Thanks!
I'm new to SwiftUI, your solution may be a little bit hard for me, but thanks a lot :D

I run into this question when trying to take a screenshot using the ImageRenderer of SwiftUI. The problem is that the picture I took is kinda weird, it appeared in the middle of the content.
For example if I rendered a Markdown view with a long content(more than one screen), the screenshot will be the middle of the content, which I want it to be at the beginning/top of it. Normally the Markdown view displays from the top of the content.

I thought the reason might be the loading process hasn't complete yet, because if you render a Markdown view of long content, you can actually see the rendering process: middle -> top

So I thought maybe if I could know when does the Markdown view rendered over, I could tell the ImageRenderer when to take the screenshot.

I saw your answer in another Q&A, you said the limitation of ImageRenderer, it can't work with async view or ScrollView.
I was confused by this a very long time
Your answer helps me a lot ! Thanks!
