In-app Updates #
The in-app updates feature is supported on devices running Android 5.0 (API level 21) or higher. Additionally, in-app updates are only supported for Android mobile devices, Android tablets, and ChromeOS devices.
How to test In-App Update
Your app can use the Google Play Core libraries to support the following UX flows for in-app updates:
Flexible Update Flows #
Flexible updates provide background download and installation with graceful state monitoring. This UX flow is appropriate when it's acceptable for the user to use the app while downloading the update. For example, you might want to encourage users to try a new feature that's not critical to the core functionality of your app.

Immediate Update Flows #
Immediate updates are fullscreen UX flows that require the user to update and restart the app in order to continue using it. This UX flow is best for cases where an update is critical to the core functionality of your app. After a user accepts an immediate update, Google Play handles the update installation and app restart.

Usage #
Package Information #
You can use PackageManager to get information about the package.
import 'package:flutter_upgrade_version/flutter_upgrade_version.dart';

Future<void> getPackageData() async {
PackageInfo _packageInfo = await PackageManager.getPackageInfo();
}

PackageInfo class - Fields:

appName : the app name
packageName : the package name
version : the package version
buildNumber : the build number
languageCode : the language code of Locale.
regionCode : the country/region code for this locale. ISO 3166 alpha-2 country code

Android: Using In-app Update #

Note: Be mindful of how often you request updates to avoid annoying or tiring your users. You should only request in-app updates for changes that are important to the core functionality of your app.

/// Android
if (Platform.isAndroid) {
InAppUpdateManager manager = InAppUpdateManager();
AppUpdateInfo? appUpdateInfo = await manager.checkForUpdate();
if (appUpdateInfo == null) return; //Exception
if (appUpdateInfo.updateAvailability == UpdateAvailability.developerTriggeredUpdateInProgress) {
///If an in-app update is already running, resume the update.
String? message = await manager.startAnUpdate(type: AppUpdateType.immediate);
///message return null when run update success
} else if (appUpdateInfo.updateAvailability == UpdateAvailability.updateAvailable) {
///Update available
if (appUpdateInfo.immediateAllowed) {
debugPrint('Start an immediate update');
String? message = await manager.startAnUpdate(type: AppUpdateType.immediate);
///message return null when run update success
} else if (appUpdateInfo.flexibleAllowed) {
debugPrint('Start an flexible update');
String? message = await manager.startAnUpdate(type: AppUpdateType.flexible);
///message return null when run update success
} else {
debugPrint('Update available. Immediate & Flexible Update Flow not allow');
}
}

iOS: Information of Version on the Apple Store #
We get the app information on Apple Store throught the package_name and regionCode.

You need to make sure the ID already exits on the Store.

RegionCode where your app will be available to purchase or download. If your app is not available across countries or regions, you can't lookup the app information on iTunes Search API. AppStoreConnect: My Apps > AppName > Pricing and Availability > App Availability

Recommnend to ensure the getiOSStoreVersion function works: The version number is shown on the App Store and should match the one you used in Xcode.

Parameter
Description

packageInfo
Required. PackageManager.getPackageInfo

regionCode
Optional. The default is US The two-letter country code for the store you want to search. The search uses the default store front for the specified country. See ISO_3166-1_alpha-2 for a list of ISO Country Codes.

///iOS
if (Platform.isIOS) {
VersionInfo? _versionInfo2 = await UpgradeVersion.getiOSStoreVersion(
packageInfo: _packageInfo,
regionCode: 'VN',
);
///Example: VN - Viet Nam
}
