How do I access Shared Preferences?

In Android, you can store a small collection of key-value pairs using the SharedPreferences API.

In Flutter, access this functionality using the Shared_Preferences plugin. This plugin wraps the functionality of both Shared Preferences and NSUserDefaults (the iOS equivalent).

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

void main() {
      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.');
  prefs.setInt('counter', counter);
