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

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

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.

}

class Home extends StatefulWidget {
  @override
