The Clash of Clans: Kotlin Vs. Flutter

First things first – Kotlin is a programing language whereas Flutter is a framework. As frameworks provide solutions to particular problems, you’ll find several inbuilt functions in Flutter to complete an application. And, of course, programming languages know no limit for app development. 

Since May 2019, Google officially supports Kotlin for mobile app development on Android. But, Flutter is an open-source mobile application development framework created by Google itself!

Both Kotlin and Flutter have a ‘Google tag’ attached with them. Therefore, ‘which is better’ is a big question before developers. Reading further, you’ll get to know ‘when’ to use Kotlin or Flutter.

When to use Kotlin?

Kotlin is a cross-platform general-purpose programming language. Although it relies on Java Class Library, its syntax is more concise. Want to know the difference between Kotlin and Java? Here’s your answer.

The scope of app development in Kotlin is unlimited. For instance, Uber’s internal tooling processes (e.g. Annotation processors, Gradle plugins, etc.) are coded in Kotlin. Pinterest app moved from Java to Kotlin to provide users a better interface.

Following are the situations where Kotlin supersedes any other programming language for mobile app development.

#1 Adding Features to an Existing App

Kotlin works well and is interoperable with Java and Java components. If you want to add features to an existing app, then instead of revamping the entire architecture or changing the platform, you can simply use Kotlin to solve the purpose.

#2 Simple Syntax for Sophisticated Codes

With intuitive syntax, it is easy to write and deploy new codes in Kotlin. For apps that require heavy coding, Kotlin is simple to maintain. 

#3 Inbuilt Debugging

Kotlin’s fail-fast compiler can search bugs automatically and prevents them from coming again. Thus, Kotlin is safer than Java and reports and resolves crashes instantly.

StackOverflow survey 2019 reveals-  Kotlin is the fourth most loved programing language!

When to use Flutter?

Flutter is a framework developed by google on Dart programming language. Its architecture includes the Dart platform, Flutter engine, Foundation library, and design-specific widgets. Flutter got the spotlight because apps developed in Flutter are compatible with both iOS and Android.

The Flutter framework is capable of building full-fledged applications in different domains like e-commerce, utility, social, and entertainment. For example, Alibaba’s mobile app is built in Flutter.

#1 For Building Minimum Viable Product (MVP)

If you want to build an application in minimum possible time, you should go for Flutter. Be it to impress investors, or present prototypes, Flutter is just sufficient (and fast too) to give a clearer idea of the product.

#2 Quick Fixes

Flutter’s hot reload feature allows developers to execute code changes in real-time. If you know, the project will require frequent changes, Flutter can give you quick fixes. 

#3 Easy Set-up

Flutter is easy to set-up, even in low-end PCs. It enables developers to access native features like Geo-location and camera along with additional widget support.

It would be unjust if we don’t discuss the situations where Flutter doesn’t meet developers’ expectations.

At present Flutter is still in its early stages. There aren’t too many CI (Continuous Integration) Platforms (e.g. Jenkins and Travis) that support it. Flutter, although makes it easy to build apps for android and iOS, does not cover web-apps. Therefore, Flutter is a misfit for businesses that require both mobile and web applications.

Now that Kotlin vs. Flutter is a hot-topic, should ‘React JS’ feel left out?

React JS, which is backed by Facebook was once popular for developing mobile user interfaces. Many developers still prefer React Native, which enables native Android, iOS, and UWP development with React. However, the new-age developers are more inclined towards Kotlin and Flutter.

What Developers say on Kotlin Vs. Flutter

“Dart is just a wannabe amateur hobby me-too project compared to Kotlin.”

Mike Milpot, Software Architect, Inventor

“Apart from the fact that you can still call Android/iOS APIs, building Flutter UIs is a bit more exhaustive than it is on Android.”

Wilberforce Uwadiegwu, Mobile Software Engineer, NCK Tech

“You can of course, use the Flutter knowledge to develop iOS apps later, so it can be a more useful knowledge if you want to focus on mobile development, but learning java will give you a step if you want to work on Back-end web development.”

Maycon Miranda, Web Developer, Bio Extratus

“Currently flutter lacks library/guide when comparing to Kotlin/Java. Therefore sometimes you’ll need to transfer or wrap Android library to flutter by yourself. It’ll make the time of developing your application increased.”

Phạm Anh Minh, Samsung Vietnam Mobile R&D Center

Final Thoughts

Kotlin and Flutter are competitive and are going to be better with every release. Experts say, if you want to strengthen back-end app development skills, you should learn Java followed by Kotlin. Thereafter, with little effort, you’ll automatically get hold of flutter.

Apple WWDC 2021, Facebook f8, Microsoft Build: What’s in it for Developers and Consumers this year

14 minutes read

Apple WWDC 2021 is the second all-virtual conference hosted by the company this year, one that will see both hardware announcements and software updates. WWDC 2021, which begins June 7 with the traditional Apple keynote will run the whole week long and will contain pavilions, daily recaps available to revisit, and more in this free-for-all developers virtual meet. 

WWDC 2021 is bringing big changes to iOS 15 and iPad OS 15, along with a new more powerful M2 chip and a redesigned MacBook Pro that gets rid of its maligned features like the Touch Bar, to re-introduce the HDMI port and MagSafe. 

Apple CEO Tim Cook began the keynote address welcoming “familiar” faces back again in the audience, virtual avatars aka Memoji instead of real people, given the ongoing pandemic.

Here’s everything we noticed at the Apple WWDC 2021 keynote: 

iOS 15 

The new iOS update will come with a series of improvements including a better Facetime experience. FaceTime will now include features like Spatial Audio making calls more comfortable and natural, like you and the person on the other end are in the same room. The mic gets a Voice Isolation update, which, through the use of Machine Learning will block ambient noise and prioritize your voice. Another noticeable update is Wide Spectrum, to capture your voice and everything around you.  

The software update also introduces Portrait mode to blur backgrounds, and a grid view to enable multi-conversations with a highlighted tile to know who the speaker is. Users can also schedule individual FaceTime calls with Facetime links, similar to Zoom. Additionally, users can share their screen, music, TV show, or movie through a new feature called ShareTime, to enable a Watch Party of their own. FaceTime will, with this update, be supported on Android and Windows through a web browser.

iMessage, the messaging platform, available only on Apple devices, will now come with features that group similar images into galleries. A brand-new feature called “shared with you” will save links that people sent you and collects them in one place. It works across Safari, Apple Music, Apple TV, and Apple Podcasts.

Notifications will now have an updated design on the lock screen, featuring a clearer look. Titled the Focus feature, users can choose to go on Do Not Disturb mode or choose Work, Life hours to be able to receive notifications depending on their preferences, much like the OnePlus Zen Mode and Work-Life Balance feature that came with the OnePlus 7 series in 2019. 

Live Text, a new camera feature, will automatically identify and scan text or visuals in photographs. Another feature called Memories will use Machine Learning and AI to combine photos into galleries and add music from Apple Music. 

Apple Maps software is also updated with 3D data with this release. It now includes lanes, clearer city details, AR-led detailed directions, and more. The Weather app gets an interactive update where data and layout will change according to weather conditions. 

A new feature is also coming to AirPods called “conversation boost” which will help people better understand who they are talking to in real-time. Siri will be able to announce messages and read out your shopping list as well. Apple Wallet adds a new functionality which now includes corporate badges.

Quicknote is a fast and easy way to get to a note saved for later, while also allowing a user to jot notes using the Apple Pencil. Consumers can now add tags to organize their notes better and even mention others in shared notes.  

With iPadOS 15, Apple is adding features for multi-tasking, bringing widgets and app library to the iPad as well. Apple has also announced an iCloud+ subscription service with a focus on privacy. 

Privacy and Security: 

New privacy features, and a subscription-based iCloud+ was also announced at the keynote. Apple is now adding new privacy features across its devices. The Mail App, for instance, will have a feature called tracker-blockers to hide your IP address, location and other information that help building a digital personality for third-party apps. An App Tracker Report section in the Settings will allow users to see how often apps have used their info in the last seven days.

iCloud+ will also include a key feature called Private Relay, which essentially helps route web traffic through two separate servers, just like VPN.

Siri, on the other hand, has some new features including availability on third-party apps, and users can also request tasks from the Voice Assistant without an active internet connection. 

Speaking of legacy contacts, Apple has introduced a Digital Legacy Program that will help your trusted contacts to manage your account, close them et al, even when you’re no longer around. 

Digital Health: 

The latest Apple Watch software allows more interaction possibilities while also connecting health trackers that monitors everything from your gait to the sleep patterns via the Breathe app called Mindfulness and let’s you know as soon as it finds something out of the ordinary which can be addressed promptly. This is possible through Apple’s collaboration with a few electronic health record companies. If you’re away from your loved ones, the new software allows you to share health data too. 

New watch faces on Watch OS8 are available in Portrait mode and one also has the ability to write a text with their finger to send a text message.

Additionally, in the Workouts app, new workout types including TaiChi and Pilates have been added guided by popular names such as Jeanette Jenkins as well as a new Artist Spotlight series that offers workouts on the music of Lady Gaga, Keith Urban, and more.

macOS Monterey: 

At the WWDC 2021 keynote address last night, Apple announced a new version of macOS. Titled Monterey, after the pristine beach town in California’s central coast, the new macOS brings a number of features including multiple screen-usage while using the same mouse and keyboard across a Mac or an iPad. This feature is called Universal Control. 

iOS devices can (for the first time) beam their screen to a Mac, thanks to AirPlay. The Safari web browser has also got a redesign with new and improved features including tab grouping and tab bookmarking. 

What piqued your interest the most at this year’s Apple WWDC? Facebook f8, held earlier this month also had a few interesting announcements. Take a look. 

WIIFM at Facebook f8? 

Facebook f8, held on June 2 this year kicked off with a promise that Facebook was returning to its roots and focusing on the developer community for this year’s virtual event. 

“This year we are refocusing F8 on developers,” Mark Zuckerberg said. “Some of the most important services in the world started when someone looked at an existing issue, and just found a better way to build. And I’m optimistic that some of the next generation of services are going to start right here with you.”  

On the business messaging front, Facebook announced that its Messenger API for Instagram is available to all developers. The social media giant is also testing a way for people to opt into messaging with businesses through a new feature called Login Connect with Messenger. 

Through WhatsApp Business API, it’s now easier for businesses to get started with using the tool effectively for their businesses. Among its key updates, Facebook said it has reduced the entire API onboarding process from weeks to five minutes. The company also announced new WhatsApp messaging features with an aim to give people a quicker way to make a selection when interacting with a business’s chatbot on WhatsApp. 

Augmented Reality, AI and Machine Learning: 

Facebook’s development of its futuristic augmented reality glasses is still ongoing, but the company has exhibited broad ambitions in terms of its AR experiences built on its SparkAR software. In the near future, Facebook has said that it wants to make it easier for developers to build augmented reality effects for group calls via its new Multipeer API.  

The SparkAR platform now has 600,000 creators in 190 countries, with 2 million AR filters and effects created to date, according to Facebook. 

PyTorch, the deep learning framework co-developed by Facebook in 2016, is now becoming the default framework for building all its AI and machine learning models in the foreseeable future. 

“PyTorch not only makes our research and engineering work more effective, collaborative, and efficient, it also allows us to share our work as open-source PyTorch libraries and learn from the advances made by the thousands of PyTorch developers all over the world,” Facebook said in a blog post. 

Missed Microsoft Build? Here are key highlights tailor-made for you: 

Microsoft Build, also a developer conference, was also held virtually this year from May 25 to 27. 

Following his keynote address, Microsoft CEO Satya Nadella wrote on a LinkedIn post, “As computing becomes embedded in every aspect of our lives, there will be no longer such thing as the tech sector. The world will be transformed through tech intensity at scale. Every organization will need to not only adopt the latest technology, but more importantly, build their own unique digital technology, or be left behind.”

“We are building the platform for platform creators. It’s not about setting new rules or constraints that dictate how or what you should build. It’s not even about celebrating our own innovation. It’s about enabling your innovation and creating new opportunities for you,” he continued. 

From Microsoft Teams that allows users to complete projects from any location and at any time without needing to switch across different apps and data, to Windows Updates providing GUI support on Windows Subsystem for Linux (WSL), it will also allow seamless integrations with other workflows with Linux, GUI apps, and GPU-accelerated ML training.

In terms of privacy and security, Microsoft announced the integration of its Azure Security Center with GitHub. This integration will further enhance collaboration between the development and security teams. Interestingly, this collaborative effort will feature an update to enable security teams to be aware of the holistic development life-cycle instead of trying and fixing bugs only once the software is released. This measure will further allow the DevSecOps teams to run vulnerability scans, resolve findings, and visualize the security of workflows within their CI/CD pipeline.

The company also announced key updates to its Azure AI services, including Azure Bot Services, Azure Video Analyzer, and more. That’s not all, Microsoft also announced ML capabilities updates to accelerate its AI model deployment, namely Azure Machine Learning Managed Endpoints and Power Fx.

Automatic Aggregations was yet another feature that debuted at MS Build this year. Power BI dataflows that suitably handle streaming data sources, starting with Azure Event Hubs and Azure IoT Hubs, promises to make streaming data and real-time analytics accessible. 

Microsoft also introduced a low-code programming tool that allows users to write code without any prior coding knowledge. Called Power App Ideas, is the first-of-its-kind collaborative effort between Microsoft and artificial intelligence (AI) research company OpenAI. The app uses OpenAI’s Generative Pre-Trained Transformer-3 (GPT-3) AI model, among one of the highly advanced natural language AI models in the world today.
