Could you please explain this - it doesn't make sense to me.

To me it seems clearly and unambiguously true that a single child is not a special case vs multiple children, but rather just a list of children that is 1 long. I can't think of any cases where handling both as an array would possibly have you write worse code.

Take the Container class in Flutter, it can only take a single Widget as a child. Having to write a list of children that is 1 long every time I use a container doesn't make sense to me, and to me seems confusing as it will lead to people trying to add more items. I don't know, that's my opinion, maybe I'm wrong :)

Hmm, perhaps it's me not understanding the flutter paradigm, but if something only accepted a single child, I would stop calling it a child and start calling it a more precise name. Like perhaps contents in the case of a container?

Sounds like they took that from Android where IIRC a scrollview could only take one child. Coming from Win32 Android, back in the G1 days, always had its own idiosyncrasies.
