Checkout Dialog too small.

I think we can increase the size of the Checkout Dialog by using a fulscreen dialog instead.

@jerryOkafor The actual reason why we went for a centred non-fullscreen dialog was an attempt to replicate the design of the Paystack web checkout UI.

You have a point though. PCs and mobile phones don't have the same screen real-estate.

Maybe we should add an optional fullscreen dialog. The configuration parameter can be passed to the checkout function. Please, what do think about this?

That would be nice. I was working on something before now, first choice was a dialog but it did not give me all I wanted and I made it a fullscreen. I am sure fullscreen would be nice.
