React call function in class component from exported function

I want to call handleChange in my BasicInfos component from the Cropper function. Here's an example code:

export default function Cropper() {
  return (
    <Crop onChange={handleChange}/> // I want to call handleChange from here
  );
}

import Cropper from "./Cropper";

@observer
class BasicInfos extends React.Component
{
   @action
   handleChange = (blob, url) => {
      tmpFile = blob;
      tmpFilePath = url;
   }
   render () {
     return (
       <Cropper action={this.handleChange}/>
     );
   }
}

You need to get the prop action

export default function Cropper({action}) {
  return (
    <Crop onChange={action}/> // I want to call handleChange from here
  );
}

import Cropper from "./Cropper";

@observer
class BasicInfos extends React.Component
{
   @action
   handleChange = (blob, url) => {
      tmpFile = blob;
      tmpFilePath = url;
   }
   render () {
     return (
       <Cropper action={this.handleChange}/>
     );
   }
}
