After initializing the appsflyersdk, but i'm getting an issue.
final AppsFlyerOptions options = AppsFlyerOptions(
afDevKey: DotEnv().env['DEVKEY'],
showDebug: true);
_appsflyerSdk = AppsflyerSdk(options);
_appsflyerSdk.initSdk();

Error:
'package:appsflyer_sdk/src/appsflyer_sdk.dart': Failed assertion: line 46 pos 12: 'devKey != null': is not true.

Hi,

I'm getting this error when trying to compile the app for iOS:

Xcode's output:
↳
    In file included from /Users/ricardocampos/.pub-cache/hosted/pub.dartlang.org/appsflyer_sdk-1.0.7/ios/Classes/AppsflyerSdkPlugin.m:1:

    #import <AppsFlyerFramework/AppsFlyerLib/AppsFlyerTracker.h>

Any idea?

Thanks!

Help, I can't find in the documentation how to get invite link string in Flutter

I've got this in my main.dart to test if an app open would register with af:

Future<void> initSdk() {
    return appsflyerSdk.initSdk().then((onValue) {
      print(onValue.toString());
    }).catchError((onError) {
      print(onError.toString());
    });
  }

  void sendEvent(String eventName, Map eventValues) async {
    bool result;
    try {
      result = await appsflyerSdk.trackEvent(eventName, eventValues);
    } on Exception catch (e) {}
    setState(() {
      print("Result trackEvent: $result");
    });
  }

@override
  void initState() {
    super.initState();
    initSdk().then((res) {
      sendEvent("app open", {
        "af_platform": Theme.of(context).platform.toString(),
        "af_action": "open",
        "af_date": DateTime.now().toIso8601String()
      });
     });
  }

Yet, I don't see anything in the af dashboard after I start the app on my simulator. Shouldn't it be reflected in the events tab or somewhere? Or am I doing something wrong? Thanks

I have successfully connected appsflyer to my app to get clicks and impressions. To get installs, i tried to install referrer to my manifest file. But it doesnt work, i dont have any numbers in my dashboard. I decided that the main problem is that i didnt init sdk.

My code to init appsflyer:

AppsflyerSdk _appsflyerSdk;
final AppsFlyerOptions options = AppsFlyerOptions(
afDevKey: DotEnv().env["DEV_KEY"],
appId: DotEnv().env["APP_ID"],
showDebug: true);
_appsflyerSdk = AppsflyerSdk(options);
_appsflyerSdk.initSdk(registerConversionDataCallback: true, registerOnAppOpenAttributionCallback: true);

I expected my app will build and i am going to test my installs. And for the first time my app has built successfully and i started testing it. I've added devices to test the app as i read in documentation. Anyway i didnt get any numbers in my dashboard. And now when i try to launch my app - i am getting this issue, when debug says:

I'am trying to init my appsflyersdk, but i'm getting an issue.
final AppsFlyerOptions options = AppsFlyerOptions(
afDevKey: DotEnv().env['DEVKEY'],
appId: DotEnv().env[APPID],
showDebug: true);
_appsflyerSdk = AppsflyerSdk(options);
_appsflyerSdk.initSdk();

I pasted this code to my initState.

What can i do? It seems like it doesn't see my key.

why the following methods are commented?

AppsflyerSdkPlugin.m
lse if([@"enableUninstallTracking" isEqualToString:call.method]){
//
}

AppsflyerSdkPlugin.java
// private void enableUninstallTracking(MethodCall call, Result result) {
// String senderId = (String) call.argument("senderId");
// AppsFlyerLib.getInstance().enableUninstallTracking(senderId);
// result.success(null);
// }

however the method call is in the appsflyer_sdk.dart

void enableUninstallTracking(String senderId) {
_methodChannel
.invokeMethod("enableUninstallTracking", {'senderId': senderId});
}

i called initappsflyersdk in main.dart initState(), it gives me warning like this, how to solve it ??

I cant find any example about validateAndLogInAppPurchase, what is the best practice for verify in app purchases ?

Describe the bug
Kindly check the AppsflyerConstants.AF_VALIDATE_PURCHASE = "validePurchase" spelling incorrectly. It causes the "_registerPurchaseValidateListener" cannot return correct result.

Expected value should be "validatePurchase".

Input params for initSdk are optional, however they don't have default values and are not checked for null. Omitting either of them results in the below exception. I'm not sure if there are any further repercussions as the result of that exception.
This happens on the latest version of the plugin: 5.2.0+1.

Executing validateAndLogInAppPurchase with information that will cause an error will cause the app to crash.

To Reproduce
Steps to reproduce the behavior:

1. Purchase something (in my case auto-renewable subscription and in Sandbox mode)
2. Pass the information to validateAndLogInAppPurchase, but do not set Sandbox mode for AppFlyer.
3. Crash

Expected behavior
No crash.

Smartphone (please complete the following information):

• Device: iPhone 11 Pro Max
• OS: iOS 14.2
• Browser: Safari

Additional context
The crash is

NSInvalidArgumentException
*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[0]

It happens because -(void)onValidateFail:(NSError*)error{ is executed with error being nil, which according to the AppsFlyer iOS SDK is valid.
In the next line, you're attempting to make a dictionary using that error.description which is nil.

Describe the bug
I have updated to the latest version of appsflyer_sdk from 1.2.1 to 1.2.2 and now receive the error

type 'String' is not a subtype of type 'Map<dynamic, dynamic>'

in my app as well as the example app

Hi,
We implemented OneLink and we are trying to redirect the user to different pages in the app based on the attribution parameters added to the OneLink custom links. This is working great when the app is closed or when it's installed from said link, as we are getting both the onInstallConversionDataLoaded and onAppOpenAttribution events, but we are not receiving anything if the app is in background and brought in foreground using OneLink. Has anyone encountered this issue before? Is there any way we could achieve this?

i have user this sdk but it never shows non-orgainic installs , can you please tell me what might be the problem?

Describe the bug
iOS build of the plugin is not calling callback of setAppInviteOneLinkId method.

To Reproduce
This code will work on android and not on iOS:

Expected behavior
iOS plugin needs to call the callback function, so the chaining call will work.

Additional context
I opened a PR #53 two weeks ago but didn't reported as an issue.

The Flutter side method is inconsistent with the native receiving processing method

in Flutter:

in Android:

in iOS:

Method trackEvent for login is not working for me. Could you please see if I've done it right? I tried to follow the example, but it always goes straight to CATCH. Help me pls?

Future _trackLogin() async {
Map eventValues = {
"af_customer_user_id": "123456789"
};
try {
var result = await afSdk.trackEvent("af_login", eventValues);
print("LOGIN $result");
} catch (e) { print(e.toString()); }
}

ERROR:
I/flutter (13259): NoSuchMethodError: The method 'trackEvent' was called on null.
I/flutter (13259): Receiver: null
I/flutter (13259): Tried calling: trackEvent("af_login", _LinkedHashMap len:1)

the code below shows how I structured to get conversion data and deeplink installs.
even with the listen() method, it doesn't bring me the data, it's like the method is not working.
can u help me? am I doing it right?

--------------------- CODE -------------------

AppsflyerSdk sdk;

@OverRide
void initState() {

super.initState();
sdk = AppsflyerSdk(
  widget.appsFlyerOptions,
);

initializeAppsFlyer();

}

initializeAppsFlyer() {

try {
  var result = sdk.initSdk();

  sdk.registerConversionDataCallback().listen((data) => onSuccess(data));
  sdk.registerOnAppOpenAttributionCallback().listen((data) => onSuccess(data));

} catch (e) {
  print('error initializing SDK: ' + e.toString());
}
return;

}

void onSuccess(result) {
var conversionData = jsonDecode(result);

if (conversionData.data.is_first_launch == true) {

  if(conversionData.data.af_status == 'Non-organic') {

    var mediaSource = conversionData.data.media_source;
    var campaign = conversionData.data.campaign;

    print('This is a Non-Organic install. Media source: ' + mediaSource + ' Campaign: ' + campaign);
  } else if(conversionData.data.af_status == 'Organic') {
    print('Organic Install');
  }

} else if (conversionData.data.is_first_launch == false) {
  print("Not first launch ");
}

}

This is the code I am using

appsflyer.setAppInviteOneLinkID('$id', (_) {
      print('setAppInviteOneLinkID success');
});

Also, when calling this method, an error is displayed in the console:
type '_InternalLinkedHashMap<dynamic, dynamic>' is not a subtype of type 'String'

Version 6.0.5+1 on pub.dev throws
The method 'onAppOpenAttribution' isn't defined for the type 'AppsflyerSdk'.

In fact, when looking at the code on the pubspec the function is not on appsflyer_sdk.dart. However, it still appears on the documentation.

Is it deprecated or replaced?

When I rerun the project the error stops showing

In my project I am using the following
Ubuntu 18.04.5 LTS
Flutter 1.22.0
Dart 2.10.0
Android Studio 4.1

And the device that I use to run the project is the following. Huawei P10 lite, this has Android 8.1

Any idea why I get this error the first time I run the project?

In-organic installs (Facebook Ads) showing up on Appsflyer dashboard correctly,
but conversion data callback reports all installs as organic.
(Tested only in Android)

final appsflyerSdk = AppsflyerSdk(AppsFlyerOptions(
  afDevKey: "MYDEVKEY",
  appId: Platform.isIOS ? "IOSKEY" : "ANDROIDKEY",
  showDebug: true,
));

  appsflyerSdk
      .initSdk(
    registerConversionDataCallback: true,
  )
      .then((_) {
    appsflyerSdk.conversionDataStream.listen((data) {
      logger.d(data);
      if (data != null) {
        amplitudeAnalytics.setUserProperties({"conversion_data": data});
      }
    });
  });

Our many customers using iOS10 crash a lot with NSRangeException in appsflyer sdk.
13 customers crash 204 times.

Stack Info:

NSRangeException
*** -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array

Appstore doesn't accept appsflyer even I disabled IDFA.
It seems there is a problem with Adsupport, how can I solve this?
Thanks

Regarding Guideline 1.3, we continue to notice that your app references the ASIdentifierManager API, which provides access to a user's IDFA, in the following location(s) in your binary:

• /System/Library/Frameworks/AdSupport.framework/AdSupport

It would be appropriate to remove all instances of “ASIdentifierManager” from your app, even if they are not utilized in your app's functionality.
