SfNavigationDrawer crashes for Xamarin forms 2.3.5 pre6

[Emil]

Hi,

I know it is in pre-release but xamarin anounced on their forum that this pre6 is closer to the final release and it is expected to be released as xamarin forms 2.4 in following days. 

I wanted to give it a try and it looks like navigationdrawer is crashing, below is the stracktrace.
