📱 Device Apps Plus #

A Flutter plugin to check whether specific Android apps are installed on the user's device.

• ✅ Supports Android SDK 21 and above
• ❌ Not supported on iOS (UnsupportedError will be thrown)

🔧 Features #

• isAppInstalled(String packageName) – Check if a specific app is installed
• checkMultiple(List<String> packageNames) – Efficiently check multiple apps at once
• openApp(String packageName) – Launch an installed app from your Flutter code (added in 1.0.2)

🚀 Getting Started #

1. Add Dependency #

In your app's pubspec.yaml:

dependencies:
  device_apps_plus: ^1.0.2

2. Use the Plugin #

import 'package:device_apps_plus/device_apps_plus.dart';

final checker = DeviceAppsPlus();

// Single app
bool installed = await checker.isAppInstalled("irando.co.id.holy_bible");

// Multiple apps
final results = await checker.checkMultiple([
    "irando.co.id.holy_bible",
    "com.facebook.katana",
    "com.instagram.android",
    "com.nonexistent.app",
]);

results.forEach((pkg, isInstalled) {
  debugPrint('$pkg: ${isInstalled ? "Installed" : "Not Installed"}');
});

// Open an installed app (returns false if not found)
bool opened = await checker.openApp("irando.co.id.holy_bible");

⚠️ Android Manifest Setup #

To support app queries on Android 11+ (API 30+), add the following to your AndroidManifest.xml:

<manifest ...>
  <queries>
    <package android:name="irando.co.id.holy_bible" />
    <package android:name="com.facebook.katana" />
    <package android:name="com.instagram.android" />
    <!-- Add any other packages your app checks for -->
  </queries>
</manifest>

📖 This is required due to Android package visibility restrictions introduced in API 30.
