 BoxConstraints forces an infinite height.
I/flutter ( 3530): These invalid constraints were provided to RenderSemanticsAnnotations's layout() function by the following function, which probably computed the invalid constraints in question:
I/flutter ( 3530):   RenderConstrainedBox.performLayout (package:flutter/src/rendering/proxy_box.dart:259:13)

getting this error with your example

return Swiper(
      itemBuilder: (BuildContext context, int index) {
        return Image.network(
          "http://via.placeholder.com/288x188",
          fit: BoxFit.fill,
        );
      },
      itemCount: 10,
      itemWidth: 300.0,
      layout: SwiperLayout.STACK,
    );
