Infinite ListView of Images freeze app or throw exceptions during layout [small app included]

seems to work fine I'm trying to make a horizontally scrolling ListView with repeatable images to make it seem like it's one long image scrolling forever (like in 2d platform game). , Hm... Docs say:
code :
///  2. The [ListView.builder] constructor takes an [IndexedWidgetBuilder], which 
///     builds the children on demand. This constructor is appropriate for list views 
///     with a large (or infinite) number of children because the builder is called 
///     only for those children that are actually visible.
return ListView.builder(
  scrollDirection: Axis.horizontal,
  itemBuilder: (ctx, index) {
    return ConstrainedBox(
      constraints: BoxConstraints(
        minWidth: MediaQuery.of(context).size.width,
        maxWidth: double.infinity,
      ),
      child: Image.asset(
        'assets/repeatable-forest.jpg',
        fit: BoxFit.fitHeight,
      ),
    );
  },
);

Is it possible to throw a java exception through the calling method of a base class that does not throw exceptions?

Does that help You only need to declare and catch "checked exceptions". You do not need to declare or explicitely catch RuntimeExceptions. So you can throw a RuntimeException and catch it whereever you like up in the hierarchy.

Throw a long list of exceptions vs throw an Exception vs throw custom exception?

I wish did fix the issue. "2. Create a custom exception class", but not for all. Wrap the exceptions in logical groups. For example you can have XmlWritingException, PaymentGatewayException and DataAccessException which wrap different exceptions depending on the scenario.
It's even possible (and preferred) to wrap the same exception in different wrapper. For example you can wrap IOException in PaymentGatewayException if payment has failed due to communication problem, but in XmlWritingException if it has failed during some i/o operation with xml. All these examples are hypothetical, but you get the idea.

help you fix your problem Set an OnClickListener for the view inside getView in the adapter. Also, you can set the name to be the tag of the rootview to make things easier. Then you can have code like this in the OnClickListener:
code :
public void onClick(View v){
    String name  = (String)v.getTag();
    doStuffWithName(name);
}

Hope this helps The provided solution here does work. I did not work in my case because he had and still has issues loading the debug informations of other libraries. If you have similar issues, make sure that he has loaded the necessary debug informations. I am not working with project references because of the project size. We are working with post build events which do copy the output libraries to a common directory which we are refering to as reference path. In my case deleting the libs there and rebuilding them did the job. He loaded the debug informations correct and was able to break even at handled exceptions.
Best regards
