I have an azure blob container name "x" and I want to check if a file name "a.jpg" exists in that blob or not and return true or false based on that. It seems easy but there isn't a clear answer when I google it.

It is clearly mentioned in the document, if you are using c# you can use ExistsAsync method
public async Task<bool> FileExists(string fileName)
{
return await directory.GetBlockBlobReference(fileName).ExistsAsync();
}

If I may ask, how did you find this repo?

I don't remember now . Either i would have used as a reference or got the sample code at that moment. Is that your repo?
You can also use REST Api if you want.

A lot more trouble... but works too.
Request The Get Blob Metadata request may be constructed as follows. HTTPS is recommended. Replace myaccount with the name of your storage account:
TABLE 1 GET or HEAD Method Request URI HTTP Version https://myaccount.blob.core.windows.net/mycontainer/myblob?comp=metadata
https://myaccount.blob.core.windows.net/mycontainer/myblob?comp=metadata&snapshot=
