A Plugin integrates The onyx Fingerprint Camera Api with Flutter

Onyx Flutter Package

This is not free software. This plugin uses the Onyx software development kits (SDKs) for Android and iOS. It requires a license agreement with:Diamond Fortress Technologies, Inc.

Package Requirements

Sample Project

To run the sample project, run Example/lib/main.dart. The sample app load to a screen that shows all of the onyx camera settings, and provides the ability to start the onyx camera with any of the settings on the initial screen.

Onyx controls

The OnyxCamera class's options contains all of onyx camera options, including the license key. please see the documentation for a complete list of the configuration options.

Once the settings are configured, simply call OnyxCamera.configureOnyx to set the onyx configurations, and OnyxCamera.StartOnyx() to start the camera.

Listen for changes to the OnyxCamera state to determine when the onyx package is configured (state=configured), is returning results(state=success), or has an error (state=error).

OnyxCamera.state.addListener(() async {
   setState(() {});
   if (OnyxCamera.state.status == OnyxStatuses.configured) {
       await OnyxCamera.startOnyx();

Here's a bare bones implementation for getting started

OnyxCamera.state.addListener(() {
   if (OnyxCamera.state.status == OnyxStatuses.configured) {
       //starts onyx after it's configured
   if (OnyxCamera.state.isError) {
       //handle any onyx related errors.  error messages are stored in the OnyxCamera.state.resultMessage variable.
   if (OnyxCamera.state.status == OnyxStatuses.success) {
       //do something when the onyx camera sends back results.  OnyxCamera.Results holds the onyx results.
//sets the license key
OnyxCamera.options.licenseKey = "xxxx";
//starts the onyx camera.

Android setup

The minimum android version supported is 21. More details for installing the plugin can be found at pub.dev.

Add the Onyx native package's repository and dependency references below to your app's android/app/build.gradle file.

android {
    lintOptions {
        disable 'InvalidPackage'
repositories {
    maven {
        url 'http://nexus.diamondfortress.com/nexus/content/repositories/releases/'
    maven {
        url 'http://nexus.diamondfortress.com/nexus/content/repositories/snapshots/'
dependencies {
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'com.google.android.gms:play-services-base:17.6.0'
    implementation 'com.dft.android:onyx-camera:7.1.1'

The plugin also needs permission to write to external storage, so in the app's AndroidManifest.xml, make sure to add the line below.

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

  • qualitynet.tflite

Adjust the app permissions

[ ] Open the project's Info.plist file, and paste the following lines at the bottom of the <dict> element.

Add the navigation controller to the iOS/Runner/AppDelegate file

#import "AppDelegate.h"
#import "GeneratedPluginRegistrant.h"
#import "OnyxPlugin.h"
@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [GeneratedPluginRegistrant registerWithRegistry:self];
    //New Code
    FlutterViewController *flutterViewController =(FlutterViewController*)self.window.rootViewController;
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:flutterViewController];
    [navigationController setNavigationBarHidden:YES];    
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    self.window.rootViewController = navigationController;
    [self.window makeKeyAndVisible];
  // Override point for customization after application launch.
  return [super application:application didFinishLaunchingWithOptions:launchOptions];
 <string>Capture fingerprint image</string>
<string>Save Onyx Image Results</string>
<string>Save Pictures</string>

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add onyx_plugin

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

  onyx_plugin: ^7.1.1

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:onyx_plugin/onyx.dart';
import 'package:onyx_plugin/onyx_camera.dart';
import 'package:onyx_plugin/onyx_fingerprint_template.dart';
import 'package:onyx_plugin/onyx_options.dart';
import 'package:onyx_plugin/onyx_results.dart';

A Plugin integrates The onyx Fingerprint Camera Api with 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.

Adobe XD plugin for Flutter with CodePen Tutorial

Recently Adobe XD releases a new version of the plugin that you can use to export designs directly into flutter widgets or screens. Yes, you read it right, now you can make and export your favorite design in Adobe XD and export all the design in the widget form or as a full-screen design, this can save you a lot of time required in designing.

What we will do?
I will make a simple design of a dialogue box with a card design with text over it as shown below. After you complete this exercise you can experiment with the UI. You can make your own components or import UI kits available with the Adobe XD.

API Integration Practices and Patterns

We all hear it so often that we almost stop hearing it: “Integration is critical to meeting users’ needs.”

Integration work consumes 50%-80% of the time and budget of digital transformation projects, or building a digital platform, while innovation gets only the leftovers, according to SAP and Salesforce. And as everyone from legacy enterprises to SaaS startups launches new digital products, they all hit a point at which the product cannot unlock more value for users or continue to grow without making integration a feature.

If I were to sum up the one question behind all of the other questions that I hear from customers, enterprises, partners, and developers, it would be something like: “Is integration a differentiator that we should own? Or an undifferentiated but necessary feature that supports what we’re trying to accomplish?”

This Refcard won’t try to answer that question for you. Rather, no matter what type of development work you do, API integration is a fact of life today, like gravity. Why? Today, experience is paramount. The average enterprise uses more than 1,500 cloud applications (with the number growing by 20% each year). Every app needs to integrate with other systems in a fluid and ever-changing application ecosystem. So instead, I’ll share some of the common practices you’re likely to contend with as well as some patterns to consider.

This is a preview of the API Integrations Practices and Patterns Refcard. To read the entire Refcard, please download the PDF from the link above.

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).


Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.


Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.

Public ASX100 APIs: The Essential List

We’ve conducted some initial research into the public APIs of the ASX100 because we regularly have conversations about what others are doing with their APIs and what best practices look like. Being able to point to good local examples and explain what is happening in Australia is a key part of this conversation.


The method used for this initial research was to obtain a list of the ASX100 (as of 18 September 2020). Then work through each company looking at the following:

  1. Whether the company had a public API: this was found by googling “[company name] API” and “[company name] API developer” and “[company name] developer portal”. Sometimes the company’s website was navigated or searched.
  2. Some data points about the API were noted, such as the URL of the portal/documentation and the method they used to publish the API (portal, documentation, web page).
  3. Observations were recorded that piqued the interest of the researchers (you will find these below).
  4. Other notes were made to support future research.
  5. You will find a summary of the data in the infographic below.


With regards to how the APIs are shared:
