/**
* Provides context such as filled/focused/error/required for form inputs.
* Relying on the context provides high flexibility and ensures that the state always stays
* consistent across the children of the `FormControl`.
* This context is used by the following components:
*
* - FormLabel
* - FormHelperText
* - Input
* - InputLabel
*
* You can find one composition example below and more going to [the demos](/material-ui/react-text-field/#components).
*
* ```jsx
* <FormControl>
* <InputLabel htmlFor="my-input">Email address</InputLabel>
* <Input id="my-input" aria-describedby="my-helper-text" />
* <FormHelperText id="my-helper-text">We'll never share your email.</FormHelperText>
* </FormControl>
* ```
*
* ⚠️ Only one `InputBase` can be used within a FormControl because it creates visual inconsistencies.
* For instance, only one input can be focused at the same time, the state shouldn't be shared.
