🚀 Initialize the ChottuLink SDK

Note: You can get the mobile SDK API KEY from ChottuLink Dashboard API Keys section

Initialize the SDK in main.dart:

import 'package:chottu_link/chottu_link.dart';

void main() async {
  /// ⚠️ Make sure to call this before call ChottuLink.init(apiKey: "your_api_key_here").
  WidgetsFlutterBinding.ensureInitialized();

   /// ✅ Initialize the ChottuLink SDK
   /// Make sure to call this before using any ChottuLink features.
   await ChottuLink.init(apiKey: "your_api_key_here");
  
   runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter ChottuLink Demo',
      home: HomeScreen(),
    );
  }
}

🦋 Generate Dynamic Links in Flutter

This guide covers how to create a Dynamic Link directly from your Flutter app using Dart.

🔗 Build a Dynamic Link

/// ✅ Import ChottuLink SDK packages
import 'package:chottu_link/chottu_link.dart';
import 'package:chottu_link/dynamic_link/cl_dynamic_link_behaviour.dart';
import 'package:chottu_link/dynamic_link/cl_dynamic_link_parameters.dart';

/// Create dynamic link parameters
final parameters = CLDynamicLinkParameters(
  link: Uri.parse("https://example.com"), // Target deep link
  domain: "yourapp.chottu.link", // Your ChottuLink domain

  // Set behavior for Android & iOS
  androidBehaviour: CLDynamicLinkBehaviour.app,
  iosBehaviour: CLDynamicLinkBehaviour.app,

  // UTM Tracking (for analytics)
  utmCampaign: "exampleCampaign",
  utmMedium: "exampleMedium",
  utmSource: "exampleSource",
  utmContent: "exampleContent",
  utmTerm: "exampleTerm",

  // Optional metadata
  linkName: "linkname",
  selectedPath: "customPath",
  socialTitle: "Social Title",
  socialDescription: "Description to show when shared",
  socialImageUrl: "https://yourdomain.com/image.png", // Must be a valid image URL
);

🧬 Create the Link

ChottuLink.createDynamicLink(
  parameters: parameters,
  onSuccess: (link) {
    debugPrint("✅ Shared Link: $link"); // 🔗 Successfully created link
  },
  onError: (error) {
    debugPrint("❌ Error creating link: ${error.description}");
  },
);
  • Default behavior is set to .app for both platforms
  • selectedPath is optional - if not provided, a random path will be generated
  • SocialParameters is optional - enhances link previews when shared
  • UTMParameters is optional - helps track campaign performance

🦋 Handle Dynamic Links in Flutter

Enable your Flutter app to receive and handle ChottuLinks seamlessly. This allows users to open specific screens when they tap a dynamic link, whether the app is running, in the background, or launched from a cold start. Integrate link handling to ensure a smooth and context-aware user experience across platforms.

🔧 Implementation Guide

/// ✅ Import ChottuLink SDK packages
import 'package:flutter/material.dart';
import 'package:chottulink_flutter_sdk/chottulink_flutter_sdk.dart';

/// 🔗 Listen for incoming dynamic links
ChottuLink.onLinkReceived.listen((String link) {

  debugPrint(" ✅ Link Received: $link");      

  /// Tip: ➡️ Navigate to a specific page or take action based on the link

});

URL Processing

Process the shortened Deeplink using the getAppLinkDataFromUrl method.
This retrieves the associated app link data and returns a ResolvedLink object containing the resolved destination URL and the original short link.

📝 Method Signature

New Feature
This method was introduced in SDK version v1.0.9+

static Future<void> getAppLinkDataFromUrl({
   required String shortUrl,
   void Function(ResolvedLink resolvedLink)? onSuccess,
   void Function(ChottuLinkError error)? onError,
});

Parameter

Parameter Type Required Description
shortUrl String ✅ Yes The shortened URL string to be resolved
onSuccess Function(ResolvedLink resolvedLink) No Called on successful link resolve
onError Function(ChottuLinkError error) No Called if link resolve fails

📤 Return Value

class ResolvedLink {
    String? link;
    String? shortLink;
    ResolvedLink({this.link, this.shortLink});
}

💻 Basic Implementation

ChottuLink.getAppLinkDataFromUrl(
   shortUrl: "https://yourApp.chottu.link/xxxxxx",
   onSuccess: (resolvedLink) {
      print("✅ Link: ${resolvedLink.link}");
      print("✅ Short Link: ${resolvedLink.shortLink}");
   },
   onError: (error) {
      print("❌ Error: ${error.message}");
   },
);
