Feature Request: onError callback

[osheron]

I think a decent amount of my personal friction with using the library could be removed if the onus of error handling was moved onto the consuming developer from the library itself.

• I'm seeing error logging in my monitoring tool from the NetworkImage not being able to load content, which is giving me false positives
• I want to be able to choose exactly how my error is presented using language of the error itself
• I want to be able to determine what I actually consider is a true error based on the content of the error

Proposed change:

• AnyLinkPreview has a property that is: Widget Function(Context, Metadata, Error) onError; , that returns a widget to be displayed in the event of a caught exception. -- Personally, I think this would trump the need for errorImage, errorBody, errorTitle, and errorWidget, but I recognize that backwards compatibility wins.

Hi @osheron

I didn't get your proposed solution. If you are asking to add onError Widget, It's already available. If you are asking to remove the other props and use onError Widget for all sorts of errors including caught & uncaught, That makes sense.

Since there's no response after the last query, I am closing this request. Feel free to open he ticket or new one if you face some issue. Thanks!

I am having an issue here as well, I have seen there is a Error widget, but I am in need of a "onError" function, that allows me to write a check in case the links fails.
