Contribution:

• @viniciusbsneto thanks for your help and input during development during this pull request. I believe that we could both learn from each other in this task.

Code example:

const countries = ['bar', 'foo'] as const

interface FieldValues {
    country: typeof countries[number] | undefined
    city: string | undefined
}

const OrderEdit = (props) => (
    <Edit {...props}>
        <SimpleForm>
            <SelectInput source="country" choices={countries} />
            <FormDataConsumer<FieldValues>>
                {({ formData, ...rest }) =>
                     <SelectInput
                         source="city"
                         choices={getCitiesFor(formData.country)}
                         {...rest}
                     />
                }
            </FormDataConsumer>
        </SimpleForm>
    </Edit>
);
