Description

When asset is loaded an error is thrown on ios only. The asset being loaded is on YouTube and has a valid SSL cert. The code that seems to be throwing the error is:
X509Certificate x509certificate = X509Certificate.fromData( data: sslCertificateMap["x509Certificate"]);

Expected behavior:
Asset should load without error

I saw a similar issue referenced here but the issue is closed.
