I got the following error message:

Error: The argument type 'Null Function(dynamic, dynamic)' can't be assigned to the parameter type 'ImageStreamListener'.

Because of this:

      image
          .resolve(createLocalImageConfiguration(context))
          .addListener((_, __) {
        animationController?.forward();
      });

fixed with:

      image
          .resolve(createLocalImageConfiguration(context))
          .addListener(
          ImageStreamListener((ImageInfo image, bool synchronousCall) {
        animationController?.forward();
      }));

Hope that helps!
