Creating OTP Input Fields with Pinput Package in Flutter

In Flutter, you can utilize the Pinput package to create input fields that facilitate user input or data entry. This package offers customizable input fields and simplifies text input for users. In this article, I will guide you through the step-by-step process of creating input fields in your Flutter application using the Pinput package and customizing these fields.

Step 1: Add the pinput package to your project dependencies. In the dependencies section of your pubspec.yaml file, add the following line:

dependencies:
  flutter:
    sdk: flutter
  pinput: ^1.2.0

Step 2: Use the Pinput widget to create your input field. The code example below demonstrates how to use the Pinput widget for a username input field:

import 'package:flutter/material.dart';
import 'package:pinput/pin_put/pin_put.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  final TextEditingController _controller = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Pinput Example'),
        ),
        body: Center(
          child: PinPut(
            fieldsCount: 4,
            controller: _controller,
            onChanged: (value) {
              // Code to execute when there is a change in the entered values
            },
            onSubmit: (value) {
              // Code to execute when the entered values are submitted
            },
          ),
        ),
      ),
    );
  }
}

In the above code, a PIN input field is created using the Pinput widget. The fieldsCount parameter determines the number of characters in the input field. The controller parameter is used to control the value of the input field. The onChanged parameter specifies the code to execute when there is a change in the entered values. The onSubmit parameter specifies the code to execute when the user completes the input.

The Pinput package simplifies the creation and customization of input fields in Flutter. It provides a range of features for managing text input and enhances the user experience.

In this article, you learned how to create and customize input fields in your Flutter application using the Pinput package. With this package, you can offer a more user-friendly and interactive experience to your users.
