import 'package:flutter/material.dart';

void main() {

}

class MyApp extends StatelessWidget {
    @override
    Widget build(BuildContext context) {
        return MaterialApp(
            title: 'Flutter JSON Demo',

            home: MyHomePage(),
    );}}
class MyHomePage extends StatefulWidget {
    @override
    _MyHomePageState...
