Official Coralogix SDK for Flutter.

The Coralogix RUM Mobile SDK is library (plugin) for Flutter The SDK provides mobile Telemetry instrumentation that captures:

HTTP requests
Unhandled / handled exceptions
Custom Log
Crashes (iOS Native - using PLCrashReporter)
Views
Session Replay (record and replay user sessions)

Coralogix captures data by using an SDK within your application's runtime. These are platform-specific and allow Coralogix to have a deep understanding of how your application works.

Installaion

Step 1 :Add Coralogix dependency

In the root folder of your flutter app add the Coralogix package: flutter pub add cx_flutter_plugin.

Step 2 :Integration

Inorder to initailized the RUM SDK, please supply both CXExporterOptions and CXDomain.

import 'package:cx_flutter_plugin/cx_http_client.dart';

class _MyAppState extends State<MyApp> {
  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  Future<void> initPlatformState() async {
    var coralogixDomain = **< Coralogix Domain >**;

    var options = CXExporterOptions(
      coralogixDomain: <CXDomain>,
      userContext: null,
      environment: '<Environment>',
      application: '<App Name>',
      version: '<App Version>',
      publicKey: '<PublicKey>',
      ignoreUrls: [],
      ignoreErrors: [],
      customDomainUrl: '',
      labels: {'item': 'playstation 5', 'itemPrice': 1999},
      debug: false,
    );

    await CxFlutterPlugin.initSdk(options);

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;
  }

Network Requests

By Using CxHttpClient The RUM SDK can catch / monitor the http traffic.

  final client = CxHttpClient(http.Client());
  await client.get(Uri.parse(url));

Unhandled / handled exceptions

For handled exceptions Use Try / Catch scheme with the reportError API.

If you have Stack Trace you can route it as follow

  try {
    throw StateError('state error try catch');
  } catch (error, stackTrace) {
    if (error is StateError) {
      // Handle the StateError
      CxFlutterPlugin.reportError(error.message, {}, stackTrace.toString());
    }
  }

 await CxFlutterPlugin.reportError('this is an error', {'fruit': 'banna', 'price': 1.30}, "");

For Unhandled exceptions

you need to wrap you runAPP function ad follow

void main() {
  runZonedGuarded(() {
    runApp(const MaterialApp(
      title: 'Navigation Basics',
      home: MyApp(),
    ));
  }, (error, stackTrace) {
    CxFlutterPlugin.reportError(error.toString(), {}, stackTrace.toString());
  });
}

Custom Log

  await CxFlutterPlugin.log(CxLogSeverity.error, 'this is an error', {'fruit': 'banna', 'price': 1.30});

Views

To monitor page / views use the following API

   await CxFlutterPlugin.setView(viewName);

Set Labels

Sets the labels for the Coralogix exporter.

   final labels = {'stock': 'NVDA', 'price': 104};
   await CxFlutterPlugin.setLabels(labels);

Set User Context

Setting User Context

 var userContext = UserContext(
    userId: '456',
    userName: 'Robert Davis',
    userEmail: 'robert.davis@example.com',
    userMetadata: {'car': 'tesla'},
  );

  await CxFlutterPlugin.setUserContext(userContext);

Shutdown

Shuts down the Coralogix exporter and marks it as uninitialized.

  await CxFlutterPlugin.shutdown();

Session Replay

Session Replay allows you to record and replay user sessions for debugging and analytics purposes.

Setup

First, initialize the Session Replay masking handler in your main() function:

import 'package:cx_flutter_plugin/cx_session_replay_masking.dart';

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  SessionReplayMasking.initialize();
  
  runZonedGuarded(() {
    runApp(const MyApp());
  }, (error, stackTrace) {
    CxFlutterPlugin.reportError(error.toString(), {}, stackTrace.toString());
  });
}

Initialize Session Replay

import 'package:cx_flutter_plugin/cx_session_replay_options.dart';

final options = CXSessionReplayOptions(
  captureScale: 1.0,                    // Screenshot scale (0.0-1.0)
  captureCompressQuality: 0.8,          // JPEG compression quality (0.0-1.0)
  sessionRecordingSampleRate: 100,      // Percentage of sessions to record (0-100)
  autoStartSessionRecording: true,      // Start recording automatically
  maskAllTexts: false,                  // Mask all text in screenshots
  textsToMask: ['password', 'credit'], // Regex patterns for text to mask
  maskAllImages: false,                 // Mask all images in screenshots
);

await CxFlutterPlugin.initializeSessionReplay(options);

Check Status

// Check if Session Replay is initialized
final isInitialized = await CxFlutterPlugin.isSessionReplayInitialized();

// Check if currently recording
final isRecording = await CxFlutterPlugin.isRecording();

Control Recording

// Start recording
await CxFlutterPlugin.startSessionRecording();

// Stop recording
await CxFlutterPlugin.stopSessionRecording();

// Shutdown Session Replay
await CxFlutterPlugin.shutdownSessionReplay();

Capture Manual Screenshot

await CxFlutterPlugin.captureScreenshot();

Masking Sensitive Widgets

Wrap any widget that should be masked in session recordings with MaskedWidget:

import 'package:cx_flutter_plugin/cx_session_replay_masking.dart';

// Basic usage - mask a widget
MaskedWidget(
  child: Text('Sensitive data'),
)

// With conditional masking
MaskedWidget(
  isMasked: true,  // Set to false to temporarily disable masking
  child: TextField(
    decoration: InputDecoration(labelText: 'Credit Card'),
  ),
)

Get Session Replay Folder Path

final folderPath = await CxFlutterPlugin.getSessionReplayFolderPath();
