On startup I call restorePurchases() to get the previous bought subscriptions.
This works fine but I also get subscriptions which where canceled by the user before!
They have status PurchaseStatus.restored and pendingCompletePurchase is true even though I called completePurchase().
How do I know if the purchase is still valid and not canceled by the user?
Future<void> initializeProAccountPurchase(context) async {
available = await IAPService.checkIAPAvailability();
if (available) {
await IAPService.restorePurchases().onError((error, stackTrace) =>
{print("error restore"), print(error.userInfo)});
await getProAccountDetails({'subs_item_purchase', 'pro_account'});
}
}

I'm using firebase cloud messaging to send notifications to devices. The problem is that the device token regenrated and added to firestore with different id in every run of the application. I want it to be generated juste once for the first installation of the application.
this is my code :
Future init() async {
_firebaseMessaging.getToken().then((token) {
saveTokens(token);
});
}
Future<void> saveTokens(var token) async {
try {
await _firestore.collection('deviceTokens').add({
'token': token,
});
} catch (e) {
print(e);
}
}
this is how I call it in the main():
await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);
await _msgService.init();
// testFirestore();
FirebaseMessaging.onBackgroundMessage(_messageHandler);
this is _messageHandler function:
Future<void> _messageHandler(RemoteMessage message) async {
print(
'background message ${message.notification!.body} + ${message.notification!.title}');
}
Actually token only refresh on one of that cases:
The app deletes Instance ID
The app is restored on a new device
The user uninstalls/reinstall the app
The user clears app data.
So you need to check in your firebase collection if your token (getted on getToken()) is saved yet before add it. If it already exists in your database, don't save it.
For example:
Future<bool> doesTokenAlreadyExist(String token) async {
final QuerySnapshot result = await Firestore.instance
.collection('deviceTokens')
.where('token', isEqualTo: token)
.limit(1)
.getDocuments();
final List<DocumentSnapshot> documents = result.documents;
return documents.length == 1;
}
The registration token may change when:
The app is restored on a new device
The user uninstalls/reinstall the app
The user clears app data.
More :
Update from Play Store - Token remains same.
When close the application and reopen it - Token remains same.
I recommend you should record that token for the user every time your app launches. Then, you don't face any problems.
(add function to init state of home page of your app)
I am trying to implement a password reset function that incorporates a SnackBar to display either success or error messages. The code shown below produces both the success message and the various error messages, as appropriate - but I never receive the password reset email from the Firebase service. I'm not sure if it's a Firebase setup issue or an issue with the code.
Future resetPassword() async {
try {
await FirebaseAuth.instance
.sendPasswordResetEmail(email: _emailController.text.trim());
_showSnackBar('Password reset link sent');
} on FirebaseAuthException catch (e) {
_showSnackBar(e.message.toString());
return;
}
}
Future<void> _showSnackBar(String msg) async {
final snackBar = SnackBar(
content: Text(msg),
);
ScaffoldMessenger.of(context).showSnackBar(snackBar);
}
Disregard. Code seems to work fine - problem was either with Firebase Auth service or my internet service provider last night. All good now.
Make sure to check your spam, because if did not add authorize rules in firebase then the reset link goes in spam mail.

I want to create user journey's using AWS Pinpoint. My mobile app is made with Flutter and using Amplify package to create events)
pubspec.yaml
amplify_flutter: ^0.2.4
amplify_analytics_pinpoint: ^0.2.4
I am calling this method to add the event
Future<void> logLogin(String userId) async {
await addEvent('_app.login', {PinPointAnalyticsKeys.userIdProperty: userId});
}
Future<void> addEvent(String eventName, Map<String, String> properties) async {
AnalyticsEvent event = AnalyticsEvent(eventName);
properties.forEach((key, value) {
event.properties.addStringProperty(key, value);
});
Amplify.Analytics.recordEvent(event: event);
await Amplify.Analytics.flushEvents();
}
Method handling the login:
Future<bool> performLogin(String username, String password) async {
//Code that handle login using email/password => userId
await _pinPoint.logLogin(userId);
}
My test journey: a user from a specific segment who does login should get an email right away.
I am having 2 issues:
Events get added to Pinpoint but after a delay (between 10 and 20min approximatively). Shouldn't it get added right away?
When event gets added (after the delay) no journey does get triggered, so no email sent, and the Pinpoint Journey Metrics doesn't change. What could be the reason?
Thank you all for your assistance, if I missed some details please let me know.
I want call permissionRequest for getting user photos. When I call permissionRequest and user didn't allow permission, then I show alert and when in custom alert user tap in allow button I want show permissionRequest again.
For this I try using photo_manager or permission_handler package. But in both packages when I second time call permissionRequest() function not show system permissionRequest
void _showGeneralAlert() {
Alert.show(
context,
title: 'Allow photo access',
button: AlertButton(
title: 'Allow',
onTap: () {
Navigator.pop(context);
_request();
})
);
}
Future<void> _request() async {
_permissionStatus = await Permission.photos.request();
if (_permissionStatus != PermissionStatus.granted) {
_showGeneralAlert();
}
}
May be because you permanently denied permission,
For this case you need to ask user to take permission default way(ask to open app settings and take
permission)
if (await Permission.photos.isPermanentlyDenied) {
// The user opted to never again see the permission request dialog for this
// app. The only way to change the permission's status now is to let the
// user manually enable it in the //systemsettings.
Print("permission permanently denied ");
openAppSettings();
}
Update
If this case not work then check your permission status,
var status = await Permission.camera.status;
print("permission status"+status.toString());
If they print restricted or permanentlyDenied. Then you need to open setting,otherwise you can ask permission
I have an API that I'm checking, and when the response changes I need to send a notification to the user. I would like to know how to do this without FCM Push Notifications.
I'm using flutter-local-notifications and background fetch (https://github.com/transistorsoft/flutter_background_fetch) to do it. On the background fetch docs it says that background fetch will do your function once every 15 minutes, which is good enough for me.
This is my initPlatformState():
Future<void> initPlatformState() async {
// Load persisted fetch events from SharedPreferences
SharedPreferences prefs = await SharedPreferences.getInstance();
String json = prefs.getString(EVENTS_KEY);
if (json != null) {
setState(() {
_events = jsonDecode(json).cast<String>();
});
}
// Configure BackgroundFetch.
BackgroundFetch.configure(
BackgroundFetchConfig(
minimumFetchInterval: 15,
stopOnTerminate: false,
enableHeadless: true,
forceReload: true,
startOnBoot: true,
),
_onBackgroundFetch)
.then((int status) {
print('[BackgroundFetch] SUCCESS: $status');
setState(() {
_status = status;
});
}).catchError((e) {
print('[BackgroundFetch] ERROR: $e');
setState(() {
_status = e;
});
});
// Optionally query the current BackgroundFetch status.
int status = await BackgroundFetch.status;
setState(() {
_status = status;
});
// 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;
}
I'm assuming that what's in the function that gets called in the fetch isn't needed for the question.
I tried this on my phone and simulator, and I used Xcode -> Simulate Background Fetch and it ran properly. It also ran properly when I opened the app. Unfortunately, it didn't run after 15 minutes. Is there something I'm missing?
How would I change my code to make the background fetch to happen every 15 minutes?
Yes, I spent lot of time trying to solve this but was not successful so I switched, I guessed what you are trying to do is to handle your own notification without Firebase or from an API like me, well this is it, after my search I was able to do this with the help of work manager package. So easy to use and implement, try it.
