UseInput isRequired and meta error

[L-Luciano]

Is your feature request related to a problem? Please describe.
I have an HOC to manage multilangue on TextInput and I would like my text input display my error message and add required on label message.

I override name of TextInput with 'source+language selected'.
I have a required validate function with default language which verify the default language is setted.
structure :
{ fr: "mon texte", en : "my text"}
If I pass my custom required validate function to textinput :
the value send to validator is only "mon texte" and display error all the time.

If I remove this validate, my validator works but the error is not displayed. Moreover, the label hasn't got the required option.

Describe the solution you'd like
I would like the isRequired is initialized like input or meta in useInput :

 // If there is an input prop, this input has already been enhanced by final-form
    // This is required in for inputs used inside other inputs (such as the SelectInput inside a ReferenceInput)
    if (options.input) {
        return {
            id: id || source,
            input: options.input,
            meta: options.meta,
            isRequired: isRequired(validate),
        };
    }

Manage the display error if my text input receive error message in meta props.

Additional context
It's complicated to add an source example because it's a large project.

Hello,
Sorry i was on holiday but it's not a "How To".
The "useInput" method use the option properties to manage "input" & "meta" but not for "isRequired".

Is it possible to change it and let the choice at developer ?

for example :

isRequired: options.isRequired || isRequired(validate)

[djhi]

Yes, can you create a PR ?

Ok,

I'll try to do it if I have time to fork project and improve that.
I never did that before so I need time.
