First of all initialize payment and ras Key in initState

use async and await

await CafebazaarFlutter.initPay(rsaKey:"Your RSA Key From CafeBazaar");

To start a purchase request from your app, call the launchPurchaseFlow method on the In-app Billing plugin

Map<String,dynamic> result = await CafebazaarFlutter.launchPurchaseFlow(
                        sku: "wm2", consumption: false,payload:"bGoa+V7g/yqDXvKRqq+JTFn4uQZbPiQJo4pf9RzJ");
 // after pay you get some data from Cafebazaar, if you get response code -1005 the payment is canceled by the user and  if get code 0  the payment is Success

  1. sku : your product id on CafeBazaar

  2. consumption : if your product is not a subscriber type you must consume it, For product consumption, set the consumption to true

consumption : زمانی که محصول شما از نوع اشتراکی نباشد و از نوع مصرفی می باشد باید ان را مصرف کنید تا در خرید ها بعدی کاربر بتواند ان را خریداری کند بجت مصرف یک محصول consumption را به صورت true تنظیم کنید

4.payload : The developerPayload String is used to specify any additional arguments that you want Bazaar to send back along with the purchase information.

  • Result If pay is success
    "isSuccess": "true",
    "message":"Success (response: 0:OK)",

To get Purchase details use below code

Map<String,dynamic> result = CafebazaarFlutter.getPurchase(sku:"your product sku") // you can find sku(product id) in your application in-app section
// you get the payment details if you consumption the product result is null


  • Security Recommendation: When you send a purchase request, create a String token that uniquely identifies this purchase request and include this token in the developerPayload.You can use a randomly generated string as the token. When you receive the purchase response from Bazaar, make sure to check the returned data signature, the orderId, and the developerPayload String. For added security, you should perform the checking on your own secure server. Make sure to verify that the orderId is a unique value that you have not previously processed, and the developerPayload String matches the token that you sent previously with the purchase request.

After Payment result check developerPayload result true or false

bool result = await CafebazaarFlutter.verifyDeveloperPayload("your developerPayload");
  • Important: Remember to unbind from the In-app Billing service when you are done with your Activity. If you don’t unbind, the open service connection could cause your device’s performance to degrade. This example shows how to perform the unbind operation on a service connection to In-app Billing called mServiceConn by overriding the activity’s onDestroy method.
await CafebazaarFlutter.dispose();

CafeBazaar In-App Billing Plugin for flutter

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.


If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.


A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSliderDatePicker with support for date range and time picker with the new style.


New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.
