Default values are not shown

Hi,
I have the following signature:
public async Task RefreshAsset(
CancellationToken cancellationToken,
[FromRoute] string assetlabel,
[FromQuery] string name = null,
[FromQuery] string schema = null)

I use the autorest command line with flags:
autorest --input-file=swagger.json --csharp --namespace=AssetRestApi.Client --add-credentials --verbose

The result as C# code is:
public virtual async Task RefreshAssetAsync(string assetlabel, string name, string schema, string xApiVersion, string xApiVersion1, RequestContext context)

Couple of questions:

• what do I need to use as a flag to keep the name and schmea with value null by default? I would like my clients to use the short version in some instances
• in the previous version of Autorest I had this: string xApiVersion = null, string xApiVersion1 = null, RequestContext context = null, and now I need to send explicit 'null'
• I noticed the order of the parameters: Uri endpoint, TokenCredential credential is the new one, theybeing flipped since last version.

Appreciate your answer,
Mihai
