Hey @sfshaza2, thanks for your attention!

What concerns me is the error message that mentions a "memory leak." I tried debugging but couldn't find any leak. Is this expected?
Also i prefer to mention visual studio so devs won't try to recompile the project on there ide ( AS,intellij,vsCode).

@DanTup, do you have any idea of this error message might be an actual leak?

[DanTup]

I'm afraid I don't know - I'm not very familiar with C++ and I don't know where this message might be coming from.

It does seem like an odd error if the issue is just that the code hasn't been recompiled though (and I'm also unsure whether it should be required to manually compile, or if flutter run should be doing it automatically?).. It could be worth someone more familiar with the Visual Studio / C++ parts to weigh in on this. (@stuartmorgan looks like you may have added some of this code, so maybe you have some ideas/opinion on this?)

[sfshaza2]

Thanks, @DanTup!

@stuartmorgan, can you weigh in?

[stuartmorgan]

I just left a comment in the issue; we should not be telling people they have to rebuild from within Visual Studio. flutter run will rebuild native code.

[stuartmorgan]

I don't see how it's possible to get this error message string from the provided example code, so this needs further debugging with repro steps; changing docs is premature (especially since the step the new text is recommending should not be necessary).

Thanks so much, @stuartmorgan! @AbdeMohlbi, I'm going to close this issue for now. Good luck debugging this!
