renderToolbar not loading any views

[aejaex]

Hi, I have tried to use the renderToolbar method to design my collapsible but only the image in imageSource is rendered, regardless of what I do. If I remove the imageSource prop then my app breaks, telling me "Either an imageSource or custom component is required".

How can I avoid the imageSource and design my toolbar using the renderToolbar method itself?

renderToolbar should return a function. If both renderToolbar & imageSource is given as props, renderToolbar takes priority. So it should work without any problems. Just use the renderToolbar instead of imageSource.
