shared_preferences dart package now supports local storage for the web from version 0.5.4.7+

Similar to shared preference on Android and iOS, the following is the code snippet for local storage on web

import 'package:flutter/material.dart';
import 'package:shared_preferences/shared_preferences.dart'; // rememeber to import shared_preferences: ^0.5.4+8


void main() {
  runApp(MaterialApp(
    home: Scaffold(
      body: Center(
      child: RaisedButton(
        onPressed: _incrementCounter,
        child: Text('Increment Counter'),
        ),
      ),
    ),
  ));
}

_incrementCounter() async {
  SharedPreferences prefs = await SharedPreferences.getInstance();
  int counter = (prefs.getInt('counter') ?? 0) + 1;
  print('Pressed $counter times.');
  await prefs.setInt('counter', counter);
}
