Renderflex overflow on the inspector screen hover card

```
════════ Exception caught by rendering library ═════════════════════════════════
The following assertion was thrown during layout:
A RenderFlex overflowed by 51 pixels on the right.

The relevant error-causing widget was
Row
description.dart:40
```

Reproduce the overflow on the inspector screen's hover card, then inspect description.dart:40 and the reported Row. Use the exception and screenshot to identify the layout constraint that causes the 51-pixel overflow; done means the hover card renders without a RenderFlex overflow.
