RenderSliverMasonryGrid:

    // Here, earliestUsefulChild is still the first child, it's got a
    // scrollOffset that is at or before our actual scrollOffset, and it has
    // been laid out, and is in fact our leadingChildWithLayout. It's possible
    // that some children beyond that one have also been laid out.
    final leadingScrollOffset = scrollOffsets.reduce(math.min);

Stackoverflow says:

This will happen when there is no matching element, i.e. when a == b is never true for any of the elements in list and the optional parameter orElse is not specified.

Bug is reported, I never saw this myself. Around 3% of my users are affected.

I'm using latest version 0.6.2.
