If you’re a Flutter developer, you’ve likely used url_launcher to open external apps. While it works for basic URLs, it often falls short for external app deep linking — like opening WhatsApp, Instagram, LinkedIn, or app store pages.

That’s where DeepLinkX comes in. It’s purpose-built for external app deep linking, with type-safe APIs, smart UX decisions, and automatic fallbacks.

🚀 What DeepLinkX Brings to the Table

  • Type-safe deep-link actions — no manual URL crafting
  • Smart fallback logic — app store or web when app isn’t installed
  • Cross-platform support — iOS, Android, MacOS, Windows, Linux and Web.
  • Many popular app stores supported — AppStore, PlayStore, Microsoft Store, Huawei AppGallery, Myket Store, Cafe Bazaar, more to come
  • Many popular apps supported — WhatsApp, Telegram, Instagram, LinkedIn, Twitter, Slack, YouTube, TikTok, and more
  • Installation checks — know before you launch
  • Utility methods — redirect to store, open supported apps

🛠 How to Use DeepLinkX

• Open a WhatsApp chat with fallback

import 'package:deeplink_x/deeplink_x.dart';
final deeplinkX = DeeplinkX();
final isLaunched = await deeplinkX.launchAction(
  WhatsApp.chatWithPhone('+1234567890'),
);

• Open Instagram profile with fallback

final isLaunched = await deeplinkX.launchApp(
  Instagram.open(fallBackToStore: true),
);

• Check if LinkedIn is installed

final installed = await deeplinkX.isAppInstalled(LinkedIn());

• Redirect to store page

await deeplinkX.redirectToStore(
  storeActions: [
    AppStore.openAppPage(appId: '389801252'),
    PlayStore.openAppPage(packageName: 'com.example.app'),
  ],
);
