🚀 Supports iOS, Android and MacOS.

Add this to your package's pubspec.yaml file:

dependencies:

$ flutter pub get

Usage

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

// Check update on button press with AlertDialog.

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Builder(
          builder: (context) {
            return Center(
              child: Column(
                mainAxisAlignment: MainAxisAlignment.center,
                children: <Widget>[
                  FlatButton(
                    child: Text('Check Update'),
                    onPressed: () {
                      final siren = Siren();
                      siren.promptUpdate(context);
                    },
                  )
                ],
              ),
            );
          }
        )
      ),
    );
  }
}

Customizing the prompt update.

value	Description	default
title	Alert title	Update Available
message	Alert Message	There is an updated version available on the App Store. Would you like to upgrade?
buttonUpgradeText	Upgrade Button Text	Upgrade
buttonCancelText	Cancel Button Text	Cancel
forceUpgrade	Hide Cancel Button	false

// Passing custom options.
siren.promptUpdate(context, 
  title: "My alert title", 
  message: "Bro, update my app", 
  buttonUpgradeText: "Download",  
  buttonCancelText: "Nop",
  forceUpgrade: true
);

Building your own prompt update.

Your can use the updateIsAvailable method to create your own way to alert the user about new updates. This method returns a boolean and you do your magic!

final siren = Siren();

FutureBuilder<bool>(
  future: siren.updateIsAvailable(),
  builder: (context, AsyncSnapshot<bool> snapshot){ 
    if (snapshot.hasData) {
      return AlertDialog(
        title: Text(title),
        content: Text(message),
        actions: <Widget>[],
      );
    }
  }
);
