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

SplashScreen Widget

class SplashScreen extends StatefulWidget {
  @override
  _SplashScreenState createState() => _SplashScreenState();
}

A StatefulWidget that holds dynamic UI logic, such as retrieving the version at runtime.

---

_SplashScreenState Class

Variables

String _version = '';

Stores the version number fetched from the platform.

---

initState()

@override
void initState() {
  super.initState();
  _loadVersion();
}

Initializes the widget and calls the method to load the app version.

---

_loadVersion()

Future<void> _loadVersion() async {
  final packageInfo = await PackageInfo.fromPlatform();
  setState(() {
    _version = packageInfo.version;
  });
}

Uses PackageInfo.fromPlatform() to retrieve the version and updates the UI.

---

build()

@override
Widget build(BuildContext context) {
  Size size = MediaQuery.of(context).size;

The layout is composed of:

• A column with a logo (Image.asset)

• Two Text widgets: one for app name and one for version

• Uses GoogleFonts.roboto for styling

Column(
  mainAxisAlignment: MainAxisAlignment.center,
  children: [
    Image.asset('assets/logo.png', width: size.width * 0.4),
    Text('HealthyWear', style: GoogleFonts.roboto(...)),
    Text('v$_version', style: GoogleFonts.roboto(...)),
  ],
),

Ensure logo.png is present in assets/ and listed in pubspec.yaml.
