### Question

I'm trying to use plugin with flat config file format for eslint, but can't figure it out. Could you update the documentation to outline how this would work.

I tried the following (without success):

```
import tseslint from "typescript-eslint"
import RNA11y from "eslint-plugin-react-native-a11y"

const config = tseslint.config(
...

{
name: "a11y",
plugins: { ...RNA11y.configs.all.plugins },
rules: { ...RNA11y.configs.all.rules }
},
...
)
```
