Dealing with this too, wondering if there is an active fix in place?

Same here, my card is showing C and C++ that I had never committed and don't show any of Java that I have used a lot.

If you want to ignore some languages, you can just add hide parameter in the request. In your case, &hide=dart

So for example:

Unsure if your Java is counted as Kotlin, as it does appear in there.

Hiding dart doesn't work, I tried, I also increased language counts but it didn't helped.

Just to add on this one, I tried to hide C++ from my language card. The reason is C++ and CMake files are autogenerated in dart projects and are not my contributions per se.
But whatever I tried I couldnt get rid of C++ from the card. I then checked out the languages.yml in Github Linguist, and added all the C++ extensions to list. But it still shows. Here is my card link if interested:

@elsowiny Thanks for your comment. We are aware of the limitations of the current language card. Several improvements have been proposed in #1801 (comment). Let's close #1516 and continue the discussion on #1801.

@EleoXDA Sorry I overlooked your actual question. I think #251 (comment) might solve your problem.

Perfect! Thanks very much 👍
