Why we can't get state in the transform function

In react-admin I want alter the form before submit, add variable from state. But value of variable is remain initial and I can't set it to actual. There is a code snippet below. How can I achieve my goal?

const MyComponent = props => {      // setSomeVariable will be called elsewhere, so the value of someVariable will be changed      const [someVariable, setSomeVariable] = useState('initial')        const transform = data => {          data['someVariable'] = someVariable  //it's value will remain 'initial'. How to set actual value?          return data      }        return <Create {...props} transform={transform}>             ...             </Create>  }  

Similar behavior was in these questions, but they were not answered:
