Usage:
Using PrgValidationField is straightforward. Simply import the component into your React project and configure it. Here's a straightforward example:

import React, { useState } from "react";
import { ValidationField } from "prgvalidationfield";

const App = () => {
  const [name, setName] = useState("");

  return (
    <div>
      <ValidationField
        label="Name"
        name="name"
        value={name}
        onChange={(e) => setName(e.target.value)}
        validators={[
          // Check if the name is not empty
          (value) => value !== "",
          // Check if the name length is between 2 and 10 characters
          (value) => value.length >= 2 && value.length <= 10,
        ]}
      />
    </div>
  );

export default App;
