Hi!

Same problem for me.

Juste changed if (imageSource.isResource()) with if ((imageSource != null) && imageSource.isResource()) on line 111 of FastImageViewConverter.java.

Same issue here using a resource on defaultSource on prod build on Android. When source is null, I get the error.

null object makes app crash #973 is still open :/

[antoinecaputo]

To fix it in your code, make sure that you always pass to FastImage at least
source={{ uri=null }}
It will crash when the source property is null.

Thanx. Will check in ou code base.
