Getting started

To use this package on iOS, you must configure the Info.plist file to allow the app to link to the App Store. Add the following entry:

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>itms-apps</string>
</array>

This allows your app to open App Store links correctly.

version: 1.2.3+XXXXXX

Here's a simple example of how to check for updates:

import 'package:flutter_update_checker/flutter_update_checker.dart';

final updateChecker = UpdateStoreChecker(
      iosAppStoreId: 564177498,
      androidAppGalleryId: 'C101104117',
      androidAppGalleryPackageName: 'com.vkontakte.android',
      androidRuStorePackage: 'com.vkontakte.android',
      androidGooglePlayPackage: 'com.vkontakte.android',
    );

void checkForUpdates() async {
  try {
    // Check if an update is available
    bool isUpdateAvailable = await updateChecker.checkUpdate();
    if (isUpdateAvailable) {
      print("An update is available!");
      // Optionally open the store link
      await updateChecker.update();
    } else {
      print("You're using the latest version.");
    }

    // Get the version from the store
    String storeVersion = await updateChecker.getStoreVersion();
    print("Latest version in store: $storeVersion");
  } catch (e) {
    print("Error checking for updates: $e");
  }
}
