Thank you for your kindness to make this tutorial. Your name will be listed as one of contributors in my project and all contributors will receive a total 10% from our apps' net revenue for 5 years. It is not much, since there are so many contributors that we chose. But at least, it will help you create more good tutorials like this. I will let you know when we reach the target revenue via email. Well, can we ask tutorial for Cloud Run integration in Dart & how to call them from Flutter? We will give you a big portion for that.

[@MikeJones3]

I sponsored you and paid.... but I still donthave access to the source doe :-(

[@MikeJones3]

I figured it out. Once you pay it not automatic you then have to accept joining...

[@antonyrapando7162]

I am SO glad I found you. I prefer more practicality when I learn new concepts and you're just perfect for that.

[@riverscuomo]

I followed this tutorial and successfully added my app the Google Play store. But my app was rejected from the Apple App Store because it does not include a "Restore Purchases" feature. This is the message I got: "To restore previously purchased in-app purchase products, it would be appropriate to provide a "Restore" button and initiate the restore process when the "Restore" button is tapped by the user. Note that automatically restoring purchases on launch will not resolve this issue."

[@paulovenz8037]

did you figure out how to fix this issue? thanks

[@mongezikhumalo4967]

Thanks for the great tutorial Sir. How do I resolve a provider error when trying to access the entitlements method from build method?

[@이승현-c2r]

Thanks for the great tutorial! If I choose "RevenueCat" in order to implement In-app purchase onto my app, and I go with the pro account, do I have to pay both "Appstore" or "Playstore" and "RevenueCat"? If so there are already two extra fees... which is kinda unfair for developers.

[@이승현-c2r]

​@@HeyFlutter That's very clever.. I've never thought about it! I was waiting for your comment. Please upload more for us :)

[@HeyFlutter]

Thanks, 이승현! 🙂 You shift all your developer costs to the customer, by calculating a higher price, that's what all developers do. Learn more about the RevenueCat pricing here: www.revenuecat.com/pricing . It is completely free for the first 10k/month of revenue each month.

[@excelhelp4595]

Hey there, can you please create a detailed video for payment profile creation on google play console. Step by step for Individual. There is no specific video available on youtube. Please if possible create a video on it.

[@HeyFlutter]

Thanks for the idea, @excelhelp4595! 🙂 I have added it to my list of ideas for future videos!

[@unaiayo5049]

When I subscribe to an app, it usually asks me for the password of my email linked to Google Play, I suppose it will serve to make the subscription in that app work for me on any device where my Google Play account is the same. But I see that in the video when you make the purchase you do not perform any email verification, therefore, that subscription will not be valid for other devices, right? And if you uninstall the app and reinstall it, you will not keep the subscription either, I imagine, since there is no email linked to the subscription.

[@HeyFlutter]

When ever i want to watch any video on flutter i used to first check for Heyflutter by Joannes Mike. If i dont see a video by you i then consider watching videos made by others. i am so sure youll make the problem so easy. However i have a little problem. i want my users access a particular page on my app after purchase of subscriptions but theres no hint on how to go about that. can you please help out? Thank you so much for your magnicifent resourceful and helping tutor

Muito obrigado pela sua aula meu amigo. Sou desenvolvedor android Kotlin, e estou estudando Flutter. Minha duvida era se existia algum material ou aula sobre assinaturas recorrentes, e você está fazendo isso... vou assistir várias vezes para eu poder aprender e vou te seguir aqui no youtube... muito obrigado.

[@BartWentink]

I can't find your IOS video for revenuecat?

[@ismailhossain964]

Recently i completed a complete flutter course on udemy. When I see your videos I feel like there are much more to learn. Specially I followed your strategy of saving pdf file in device. Currently I am developing an application where user database are saved in firestore, and other database like invoices are saved in local device via sqflite. So I wanted to create pdf for daily and monthly sales statement where data must come from both firestore and sqflite. Luckily i found your video. Now I am working on another feature namely invoice printing. Once "order" button placed I want to print receipt in thermal printer. For me very difficult to do since I learnt flutter recently; just for one month right now. And I dont have any other developing knowledge at all. Therefore, after completing this App I will highly consider learning from you by buying your course.

[@HeyFlutter]

Thank you, Ismail Hossain! 🙂 for printing you can refer to this package : pub.dev/packages/printing

Great tutorial, can you make a tutorial about admob ads mediation with facebook audience network? And how we can make a class that hold all the logic and functions of admob ads instead of using with the widget? I can't find any tutorials that explain this and i like your explanation so it will be a great idea to make us such as this tutorial, thanks in advance

[@delfme1872]

Thx. Can you make one for competitor platform Qonversion?

[@someguy007]

Really great. Thanks a lot. My app keeps crashing right after pressing "1-Ta-Buy" and getting "Payment Successful". But Instead of returning to App Activity, it exits app with "App has Stopped Running" warning. Do you know how I can fix this. RevenueCat shows that the payments went through.

[@someguy007]

@@HeyFlutter Hi, thanks for your reply. I followed the steps again and researched the issue for a couple of days now. Not sure whats wrong with the "1-Tap-Buy" code coz everything else works well: Purchases go through on RC and I even get a confirmation from Google Play via email but right after "payment success"... app just crashes with errors: D/[Purchases] - DEBUG(18490): Requesting products from the store with identifiers: 10_coins D/AndroidRuntime(18490): Shutting down VM E/AndroidRuntime(18490): FATAL EXCEPTION: main ......... E/AndroidRuntime(18490): java.lang.NoSuchMethodError: No virtual method getSku()Ljava/lang/String; in class Lcom/android/billingclient/api/Purchase". Not sure whats the problem. Any ideas? @ 22:27 your "onClickedPackage" opens up the Package PayWall with PurchaseApi.... , but the onclick code for "1-Tap-Buy" @25:14 is handled behind the scenes. Is there a way to see whats in that code. I think thats where my problem is. Theres no clear Exception Error.

Do we have to use in app purchases or can use a payment gateway for the same thing ?
