Many times we need to force upgrade mobile apps on users' mobile. Having faced this issue multiple times decided to find a better way to tackle this problem. After doing some research on how people are doing this there are so many custom solutions or checking with the play store or AppStore API if there is a new version available. Although this works if we just want to nudge users that there is a new version available. It doesn't solve the problem where we want to make a decision.. whether it's a soft graceful update or we want to force update. So here is this product that will make developers' life easy. We can set custom messages.. see the versions in beautify dashboard, and many exciting features in the roadmap ahead.

App Upgrade is a cross platform solution to getting users to easily update your app.

Stores Supported:
Apple App Store Google Play Store Amazon App Store Huawei AppGallery Other Android Markets
✓ ✓ ✓ ✓ ✓ If your app market place isn't one of these you can pass your own store URL.

Installation

With flutter

flutter pub add app_upgrade_flutter_sdk

Import the package

import 'package:app_upgrade_flutter_sdk/app_upgrade_flutter_sdk.dart';

How to use it.

  1. Register on App Upgrade and follow the instructions to create project and get the x-api-key.

  2. Wrap the body widget with the AppUpgradeAlert widget, provide x-api-key, appInfo of your app and rest will be handled.

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  MyApp({
    Key key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {

    AppInfo appInfo = AppInfo(
      appId: 'com.android.com' or '1549468967', // Your app id in play store or app store
      appName: 'Wallpaper app', // Your app name
      appVersion: '1.0.0', // Your app version
      platform: 'android', // App Platform, android or ios
      environment: 'production', // Environment in which app is running, production, staging or development etc.
      appLanguage: 'en' // App language ex: en, es etc. Optional.
    );

    return MaterialApp(
      title: 'App Upgrade Flutter Example',
      home: Scaffold(
          appBar: AppBar(
            title: Text('App Upgrade Flutter Example'),
          ),
          body: AppUpgradeAlert(
            xApiKey: 'ZWY0ZDhjYjgtYThmMC00NTg5LWI0NmUtMjM5OWZkNjkzMzQ5', // Your x-api-key
            appInfo: appInfo,
            child: Center(child: Text('Hello World!')),
          )
      ),
    );
  }
}

Optionally you can also provide dialog cofiguration such as dialogStyle (material or cupertino). Full details is below.

  dialogStyle: DialogStyle.material, // cupertino or material, default is material
  title: 'App update required!', // Title that will be shown in the Diaglog. Default is "App Update Required!"
  updateButtonTitle: 'Update Now', // Update button title. Default is "Update"
  laterButtonTitle: 'Later' // Later button title. Default is "Later"
  onUpdateCallback: () {} //Optional, If the user clicks on the Update button the SDK will call the onUpdateCallback.
  onLaterCallback: () {} //Optional, If the user clicks on the Later button the SDK will call the onLaterCallback.

Example with Dialog Config:

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  MyApp({
    Key key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {

    AppInfo appInfo = AppInfo(
      appId: 'com.android.com' or '1549468967', // Your app id in play store or app store
      appName: 'Wallpaper app',
      appVersion: '1.0.0',
      platform: 'android',
      environment: 'production',
      appLanguage: 'en' // App language ex: en, es etc. Optional.
    );

    DialogConfig dialogConfig = DialogConfig(
      dialogStyle: DialogStyle.material,
      title: 'App update required!',
      updateButtonTitle: 'Update Now',
      laterButtonTitle: 'Later'
      onLaterCallback: () { print("Later callback") }
    );

    return MaterialApp(
      title: 'App Upgrade Flutter Example',
      home: Scaffold(
          appBar: AppBar(
            title: Text('App Upgrade Flutter Example'),
          ),
          body: AppUpgradeAlert(
            xApiKey: 'MmQwMDU3YWEtNmEzOC00NjQ4LThlYWItNWQ4YTI3YzZdfjdkfdkfdg5',
            appInfo: appInfo,
            dialogConfig: dialogConfig,
            child: Center(child: Text('Hello World!')),
          )
      ),
    );
  }
}

Example with store other than app store or play store.

If you want users to redirect to store other than app store or playstore. You can add these additional parameters preferredAndroidMarket see the example below.

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  MyApp({
    Key key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {

    AppInfo appInfo = AppInfo(
      appId: 'com.android.com' or '1549468967', // Your app id in play store or app store
      appName: 'Wallpaper app', // Your app name
      appVersion: '1.0.0', // Your app version
      platform: 'android', // App Platform, android or ios
      environment: 'production', // Environment in which app is running, production, staging or development etc.
      appLanguage: 'en' // App language ex: en, es etc. Optional.
      preferredAndroidMarket: PreferredAndroidMarket.amazon // or PreferredAndroidMarket.huawei or PreferredAndroidMarket.other If not provided default is Google playstore. Optional
    );

    return MaterialApp(
      title: 'App Upgrade Flutter Example',
      home: Scaffold(
          appBar: AppBar(
            title: Text('App Upgrade Flutter Example'),
          ),
          body: AppUpgradeAlert(
            xApiKey: 'ZWY0ZDhjYjgtYThmMC00NTg5LWI0NmUtMjM5OWZkNjkzMzQ5', // Your x-api-key
            appInfo: appInfo,
            child: Center(child: Text('Hello World!')),
          )
      ),
    );
  }
}
  • preferredAndroidMarket: PreferredAndroidMarket.amazon // or PreferredAndroidMarket.huawei or PreferredAndroidMarket.other If not provided default is Google playstore. If SDK fails to open preferred market place in case marketplace is not available then default Google playstore will be open.

If you want to redirect user to some other android market place you can use the following example:

preferredAndroidMarket: PreferredAndroidMarket.other
otherAndroidMarketUrl: 'https://someotherandroidmarket.com/app/id'// Required if preferredAndroidMarket is Other.

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  MyApp({
    Key key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {

    AppInfo appInfo = AppInfo(
      appId: 'com.android.com' or '1549468967', // Your app id in play store or app store
      appName: 'Wallpaper app', // Your app name
      appVersion: '1.0.0', // Your app version
      platform: 'android', // App Platform, android or ios
      environment: 'production', // Environment in which app is running, production, staging or development etc.
      appLanguage: 'en' // App language ex: en, es etc. Optional.
      preferredAndroidMarket: PreferredAndroidMarket.other // or PreferredAndroidMarket.Huawei or PreferredAndroidMarket.Other If not provided default is Google playstore. Optional
      otherAndroidMarketUrl: 'https://someotherandroidmarket.com/app/id'// Required if preferredAndroidMarket is other.
    );

    return MaterialApp(
      title: 'App Upgrade Flutter Example',
      home: Scaffold(
          appBar: AppBar(
            title: Text('App Upgrade Flutter Example'),
          ),
          body: AppUpgradeAlert(
            xApiKey: 'ZWY0ZDhjYjgtYThmMC00NTg5LWI0NmUtMjM5OWZkNjkzMzQ5', // Your x-api-key
            appInfo: appInfo,
            child: Center(child: Text('Hello World!')),
          )
      ),
    );
  }
}

For IOS, if you want to redirect user to some other store you can use the following parameters:

  • preferredIosStore: PreferredIosStore.other
  • otherIosStoreUrl: "https://otheriosstoreurl.com/app/id"// Required if preferredIosStore is Other.

Note:

  1. For opening the app store/playstore the app should be live.
