Opt-out

When Opt-out is enabled, the SDK stops sending all events.

Flutter SDK is built on top of Android SDK and iOS SDK.

Configure at Initialization

import "package:hackle/hackle.dart";

HackleConfig config = HackleConfigBuilder()
    .optOutTracking(true)
    .build();

await HackleApp.initialize(YOUR_APP_SDK_KEY, hackleConfig: config);

Runtime Opt-out Control

await HackleApp.setOptOutTracking(true);
await HackleApp.setOptOutTracking(false);
bool isOptOut = await HackleApp.isOptOutTracking();

Persistence Management

The Opt-out state changed at runtime is reset to the value set in the initialization Config when the app restarts.

To persist the state across app restarts, you must implement your own save and restore logic.

import 'package:shared_preferences/shared_preferences.dart';
import 'package:hackle/hackle.dart';

Future<void> saveOptOutState(bool optOut) async {
    final prefs = await SharedPreferences.getInstance();
    await prefs.setBool('hackle_opt_out', optOut);
    await HackleApp.setOptOutTracking(optOut);
}

Future<HackleConfig> getOptOutConfig() async {
    final prefs = await SharedPreferences.getInstance();
    final optOut = prefs.getBool('hackle_opt_out') ?? false;
    return HackleConfigBuilder()
        .optOutTracking(optOut)
        .build();
}

final config = await getOptOutConfig();
await HackleApp.initialize(YOUR_APP_SDK_KEY, hackleConfig: config);
