PubSub category for Flutter
The AWS Amplify PubSub category is only available for JavaScript based projects. Is this category on the Flutter roadmap?
+1 from me as well, using mqttclient with SigV4 urls is way to much just to authenticate. Iot is fueled by mobile and flutter is already gaining a momentum so i think this is a VERY much needed in order to increase Amplify consumption.
we are waiting for this feature anyway, I think they are very important!

@flutteresbolivia - We are currently exploring what it would take to enable this for our flutter developers. Can you give me a high level understanding of the use cases you have?
estamos esperando esta función de todos modos, ¡creo que son muy importantes!
@flutteresbolivia : actualmente estamos explorando lo que se necesitaría para habilitar esto para nuestros desarrolladores de flutter. ¿Puede darme una comprensión de alto nivel de los casos de uso que tiene?
the application that we develop in real time almost 80%! We use services such as Pusher that are paid to meet the client's expectations, but this comes with high prices since the service is expensive.
for the same reason we hope this library to implement in our project, in order to use all the aws services and not third parties
Understood! And what features are you currently using with Pusher? @miguelflores1993 ? We just want to make sure we understand how developers would utilize a PubSub category enabled via Flutter.

Mobile application is very important entity in IoT (Internet of Things) that is a hot trend of Industry 4.0. In IoT, we use MQTT using PubSub protocol to connect everything including Mobile App together. That is reason all mobile libs currently support PubSub as well as MQTT (React-native, amplify javascript and so on). AWS has AWS IoT service. I think AWS earns a lot of money from this service. Many big company used AWS IoT for their backend.
@pdt590 - thank you for the feedback and context! We are still exploring whether we will support this feature this year. We will update this ticket with our findings as we learn more.
Also my two cents - pub sub is criticall for me for shadow Updates and state reporting via mqtt, additionally getting most sensor values directly just by subscribing to mqtt topic gives Us information quicker and way more cost Effective without resorting to some lambda hocus pocus for such a simple use case.

@liu731 - can you please elaborate on what your use cases are for PubSub?

Thanks for your reply, Pubsub makes it easy to get IoT device status. Currently I have to use mqtt_client and I need to manually sign with SigV4 every time I connect.
If this a feature you would like to see implemented, please give the issue a 👍. We use that to quickly gauge how much interest there is in an issue. The "+1" comments are much harder to see at a glance. Thank you.
We really need it - that will open a do an entire landscape of building mobile apps with IoT Core, is that considered on the roadmap ?
@amizer12 - can you give us an idea on the use cases you want to enable?
Hi, Sure- basically having a pub/sub within this SDK would allow for a direct interaction with devices connected via IoT Core, right now if you wan t to do this with mobile app you need to use flutter mqtt client and on top of that manage the SiGv4 authentication for every login. With Pub/Sub integrated into this SDK this would offload all those things from the devs and allow for faster and smoother IoT mobile app development which is key for the entire connected devices landscape. With pub/sub you can just focus on device shadow CRUD actions and other product specific logic instead of spending a lot of initiall time just on managing interactions between different AWS services..
Got it - thank you so much for the feedback @amizer12 ! This is really helpful to help us understand which features we need to prioritize. I can see you already gave a thumbs up to this issue as well which is great! We will keep this issue updated when we have clarity on when it can potentially land.
Have you also explored using subscriptions with AWS Appsync for your IoT use case?
Hi @abdallahshaban557 many thanks for your reply. Yes - appsync in theory would work but it's way too much additional elements to introduce comparing to a direct communication with IoT Core. For AppSync you would need to add Lambda to update a data set for appsync - that adds at least 2 additional elements to the architecture increasing it's complexity and also drives the cost up. Not mentioning that adding a Lambda will increase a processing time significantly for every simple device state update.
@amizer12 - got it - that makes sense! Thank you for sharing this feedback! It is essential to help us prioritize the right features!
Hi @UtkarshSingh5474 - can you please provide us with the use cases you are looking to build with PubSub?
Hi @UtkarshSingh5474 - can you please provide us with the use cases you are looking to build with PubSub?
Hi @abdallahshaban557. Thank you for replying. I am interested in utilizing the AWS Amplify pub/sub feature; however, it is not available in the Flutter SDK. To use this feature, I must use the Flutter MQTT client and manage SiGv4 authentication for each user. Due to this limitation, I am currently developing my IoT mobile application using React Native since AWS Amplify has pub/sub for that platform. I kindly request that you enable the pub/sub feature for the Flutter SDK so that I can build my application using Flutter.
With a direct pub sub implementation in flutter sdk, i can save a lot of costs in computation resources.
Hello - we do not have an update yet on this feature. Can you please help us understand which use cases you have for PubSub? @kalismeras61 ?
