Syntax nesting is not supported

[fuyunmanbu]

such as ~~**hello**~~ Cannot be recognized at the same time

Do you see this with various syntaxes, or just strikethrough (~~)?

This effect works at the same time

All of those examples have strikethrough. I imagine it only affects strikethrough.

I will fix that

@fuyunmanbu I got what you mean. 🙂 The markdown package itself has no problem to parse the nesting strikethrough and strong emphasis, for example

markdownToHtml('~~**hello**~~', extensionSet: ExtensionSet.gitHubFlavored)

will output:

<p><del><strong>hello</strong></del></p>

You might need to report it here if you are using flutter_markdown.

I found the problem after the test. I can support English, but not Chinese. Can you solve this problem?

I seem to have found the problem. There should be no content around

[fuyunmanbu]

It's not about language

@fuyunmanbu Got it, thanks!

Then it is the expected behavior. Our StrikethroughSyntax follows the rules of CommanMark delimiter run, it means if a left ~~ is followed by a Unicode punctuation character it must be preceded by a Unicode whitespace or a Unicode punctuation character.

So these strikethroughs are valid:

Hello ~~**Markdown**~~!
Hello:~~**Markdown**~~!

But not this one:

Hello~~**Markdown**~~!

Okay. Thank you very much.
