<input type="file" onChange={handleChange} />

onChangeFile = event => {
const image = event.target.files[0];
if (!image) {
 console.log('image is required');
 return false;
 }
 if (!image.name.match(/\.(jpg|jpeg|png|gif)$/)) {
   console.log('select valid image.');
  return false;
 }

try this.

/* you can use for file input with image validation

let handlefile = (e) => {
    let selectedFile = e.target.files[0];
    const maxSize = 2 * 1024 * 1024; 
    const allowedTypes = ['image/png', 'image/jpeg'];

    if (!allowedTypes.includes(selectedFile.type)) {
      setFileError(true);
      setFileErrorMessage("File type must be png or jpg");
    } else if (selectedFile.size > maxSize) {
      setFileError(true);
      setFileErrorMessage("File size must be less than 2 MB");
    } else {
      setFileError(false);
      setFileErrorMessage("");
    }
    setFile(selectedFile);
  };
