Seems like this code isn't correct, since TextSpan is not documented as accepting null children

No, but it does need an ignore on dead code:

looks like the point of this test was to check that our null checking gave a pretty error message. What's the error message now? Is it still pretty?

It depends:
- weak-mode, no null assertions - same error message
- weak-mode, null assertions - null assertion error when constructing the TextSpan. Depending on the context that might be easy to read or ugly
- strong-mode, static error can't be hit.
