I wanted to Export the value of SketchField
Hi @tbolis, 

Just wanted to know, Where can I get the value of the whiteboard after drawing.. something like exporting or is there any way to get the value of the SketchField whatever it stores.

I need a data on export like this file `data.json.controlled.js` have.
So, that I can load that data at any time..
i.e.,
`<SketchField width='1024px' 
                         height='768px' 
                         tool={Tools.Pencil} 
                         lineColor='black'
                         lineWidth={3}
                        value={something}
/>`
Can you please help me in this. 

Thanks in advance.
