// Stateless function that we pass to the 'component' prop of the <Field> to render
// <MUIPlacesAutocomplete>. By passing the props that <Field> passes our stateless function as the
// 'textFieldProps' on <MUIPlacesAutocomplete> we are essentially stating that the <Field> would
// like to control the state of the resulting <input> element that gets rendered. This is due to the
// addition of the 'value' property that gets spread onto the object passed to the 'textFieldProps'
// prop.
//
// It is important to define this stateless function outside of the method that renders the actual
// <Field> to avoid causing it to re-render. For more info please refer to the following docs:
// https://redux-form.com/7.2.0/docs/api/field.md/#2-a-stateless-function
