[strozw]

🐛 Bug Report

Overwriting Theme withxstyled v3.1 or later will cause a type error if you specify a value that does not exist in theme into utility props.

To Reproduce

1. Overwrite Theme by referring to the document Use xstyled with TypeScript.
2. specify a value that not exist in theme into utility props (example: <x.div w={123} /> or <x.div w={false}>

Expected behavior

If expect the same behavior as with v3.0, it should work like this:

• utility props type checking allow value that not exist in theme
• utility props type checking allow false
