Installation #

In the dependencies: section of your pubspec.yaml, add the following line:

  countly_flutter: <latest_version>

Usage #

import 'package:countly_flutter/countly_flutter.dart';

void main() {
  // If you want to catch Dart errors, run your app inside a Zone and pass Countly.recordDartError as the onError parameter to it.
  runZonedGuarded<void>(() {
    runApp(MaterialApp(home: const MyApp()));
  }, Countly.recordDartError);

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  State<MyApp> createState() => _MyAppState();

class _MyAppState extends State<MyApp> {
  void initState() {

    // Initialize the SDK once
    Countly.isInitialized().then((bool isInitialized) {
      if (!isInitialized) {
        // Create the configuration with your app key and server URL
        final CountlyConfig config = CountlyConfig(SERVER_URL, APP_KEY)..setLoggingEnabled(true);
        // In this example, we have logging enabled. For production, disable this.

        // Initialize with that configuration
        Countly.initWithConfig(config).then((value) {
            Countly.start(); // Enables automatic view tracking

  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('Countly Example App')),
      body: Center(
        child: TextButton(
          onPressed: () {
            // record an event
            Countly.recordEvent({'key': 'Basic Event', 'count': 1});
          child: Text('Record Event'),

Enabling Automatic Crash Handling #

// This will automatically catch all errors that are thrown from within the Flutter framework.
final CountlyConfig config = CountlyConfig(SERVER_URL, APP_KEY)

Reporting Exceptions manually #

// Manually report a handled or unhandled exception/error to Countly
Countly.logException('This is a manually created exception', true, null);

Recording Events #

// Record events (User interactions)

final event = {'key': 'Basic Event', 'count': 1};
Countly.recordEvent({'key': 'Basic Event', 'count': 1});

// you can also record events with segmentation
event['segmentation'] = {'Country': 'Turkey', 'Age': '28'};
Countly.recordEvent({'key': 'Basic Event', 'count': 1});

Recording Views #

// Record screen views

final segmentation = {'Country': 'Turkey', 'Age': '28'};

// start recording view with segmentation. NB: Segmentation values are optional.
final String? id = await Countly.instance.views.startView('HomePage', segmentation);

// stop recording view with name with segmentation
await Countly.instance.views.stopViewWithName('HomePage', segmentation);

// stop recording view with ID with segmentation
await Countly.instance.views.stopViewWithID(id, segmentation);

// stop recording all views with segmentation
await Countly.instance.views.stopAllViews(segmentation);

Change Device ID #

// A device ID is a unique identifier for your users/device.

// Change device ID with merge.
// Here, the data associated with the previous device ID is merged with the new ID.
await Countly.changeDeviceId('123456', true);

// Change device ID without merge.
// Here, the new device ID is counted as a new device.
await Countly.changeDeviceId('123456', false);

Get Device ID Type #

// To fetch the device ID type
final DeviceIdType? deviceIdtype = await Countly.getDeviceIDType();

User Profile #

// To provide information regarding the current user, use this.

final Map<String, Object> options = {
  'name': 'Name of User',
  'username': 'Username',
  'email': 'User Email',
  'phone': 'User Contact number',
  'gender': 'User Gender',

// Increment custom property value by 1

// Increment custom property value by 10
Countly.instance.userProfile.incrementBy('incrementBy', 10);

// Multiply custom property value by 20
Countly.instance.userProfile.multiply('multiply', 20);

// Save max value between current value and provided value
Countly.instance.userProfile.saveMax('saveMax', 100);

// Save min value between current value and provided value
Countly.instance.userProfile.saveMin('saveMin', 50);

// Set custom property value if it doesn't exist
Countly.instance.userProfile.setOnce('setOnce', '200');

// Add unique value to custom property array
Countly.instance.userProfile.pushUnique('pushUniqueValue', 'morning');

// Add unique value to custom property array if it does not exist
Countly.instance.userProfile.push('pushValue', 'morning');

// Remove value from custom property array
Countly.instance.userProfile.pull('pushValue', 'morning');

// Send/Save provided values to server. After setting values, you must save it by calling save();;

// Clear queued operations / modifications
// For compatibility with data protection regulations, such as GDPR, the Countly
// Flutter SDK allows developers to enable/disable any feature at any time depending
// on user consent.

// Consent values: sessions, events, views, location, crashes, attribution, users, push, starRating, apm, feedback, remoteConfig

// Consent can be enabled during initialization
final CountlyConfig config = CountlyConfig(SERVER_URL, APP_KEY)

// Or after initialization using one of the below methods
// give multiple consent
Countly.giveConsent([, CountlyConsent.views, CountlyConsent.crashes]);

// remove multiple consent
Countly.removeConsent([, CountlyConsent.views, CountlyConsent.crashes]);
