a Flutter widget that automatically scrolls a focused text field (or any other focusable widget) into view when the keyboard appears

VisibleOnFocus

VisibleOnFocus is a Flutter widget that automatically scrolls a focused text field (or any other focusable widget) into view when the keyboard appears. This helps ensure that the focused widget remains visible and centered on the screen, making user interaction smoother, especially on mobile devices where the keyboard may obscure the view.

Features

• Automatically scrolls the widget into view when it receives focus.
• Keeps the widget centered in its scrollable parent when the keyboard is displayed.
• Lightweight and easy to integrate with existing TextField or TextFormField widgets.

Installation

Add the following line to your pubspec.yaml file under dependencies:

dependencies:
  visible_on_focus: ^0.0.1

Then run the following command:

flutter pub get

Usage

Wrap any focusable widget (like TextField, TextFormField, or custom input fields) inside the VisibleOnFocus widget to ensure it remains visible when it gets focused.

Example

import 'package:flutter/material.dart';
import 'package:visible_on_focus/visible_on_focus.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Visible On Focus Example',
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Visible On Focus Example'),
        ),
        body: const Padding(
          padding: EdgeInsets.all(16.0),
          child: MyForm(),
        ),
      ),
    );
  }
}

class MyForm extends StatelessWidget {
  const MyForm({super.key});

  @override
  Widget build(BuildContext context) {
    return ListView(
      children: const [
        SizedBox(height: 700), // Spacer to demonstrate scrolling
        VisibleOnFocus(
          child: TextField(
            decoration: InputDecoration(
              labelText: 'Enter Text',
              hintText: 'Focus here to scroll',
            ),
          ),
        ),
        SizedBox(height: 300), // More content to demonstrate scrolling
      ],
    );
  }
}

Parameters

• child: The widget (typically a TextField or other focusable widget) that should become visible when it gains focus.

Example Explanation

In the example, the TextField is wrapped inside the VisibleOnFocus widget. When the TextField is focused and the keyboard appears, the widget automatically scrolls into view, keeping the text field visible and centered in the viewport.
