Is Flutter framework stable for the production of enterprise mobile app development?

Flutter, Google’s toolkit for building native apps on iOS and Android.

from a single code base. We’ve seen global brands from all around the world using Flutter to build their apps. These challenges all still exist because the current options out there all involve compromise.

In fact, there are two main ways to build apps today, each which poses a different set of compromises on these four priorities.

We call it the dilemma of mobile app development.

Flutter’s a third approach, one that calls for neither of these sets of compromises.

It’s fully native. Everything written in Flutter compiles directly to native machine code, meaning what you get on your phone, it is exactly what was written.

There’s no context switch. But it’s also a single code base.

So you get that straight path to the castle.

You can go to flutter.dev and download it directly, or if you already have Flutter, simply update.

Google had launched Flutter Create, which is a competition for developers to build an app in Flutter in less than 5 kilobytes of Dart code. And we have some really cool prizes, but it’s also a fun way to get quickly involved in the Flutter community and onboarded with the platform.

Now, there are 3 common ways people are using Flutter today.

The first is to build a brand new app from scratch using Flutter. So if you have an idea or an app that you want for your business, now would be a perfect time. Because you develop in one place, ships natively on all platforms.

The second way is to actually build Flutter for the other OS. What we mean by that is, if you already have an iOS or Android application, and you want to build the other one to reach more users, you can build that other one with Flutter and get it out quickly and eventually merge the codebases.

And thirdly, add Flutter to your existing app.

I’m sure many of you and your businesses already have applications. The good news is you can use Flutter for that.

Flutter Had high customization of the natively available elements.

It is stable, so there’s no performance degradation when merchants used the app for business.

If there’s anything that we want to do to extend Flutter, either on top by building our apps or in the middle, by forking it or adding functionality in between, that you can do that.

So at the bottom of the architecture is the engine. And this is built in C++ code. It’s meant to be the fastest possible thing it can be. So it’s built at the low level to do a drawing and low-level rendering.

Now, on top of that, everything else is built with Dart. When it comes to features of a modern UI framework.

How much does cost to build social media app?

vishal kumar — Mon, 04 Nov 2019 09:37:07 +0000

how to build your own social media app, how much does it cost and how much time it will take?

Social Media App

Social media is one of the leading ways to lead grab internet users. These all social media apps like Facebook, Twitter, LinkedIn, Instagram and many more taking lead on the internet and people love to spend their time on social media and communicate with people and share their opinion to each other.

Social Media is a platform where people can join with their personal details and interact with user around the world are currently using the app without any cost. Here, people love to share ideas, personal emotions, what they feel and their business and many more. (But they have to follow social media privacy and policy while posting their content.)

What kind of Social App we are going to talk about?

Here I am going to talk about a basic social media mobile app like Twitter. It has the basic functionality that Twitter has. This app Inspired by Twitter.

Account creation and User authentication:

Here users can sign up with their details. Like email, name, username and phone number. Then they need to authentication or verified their account so we can stop spam users' accounts. So you will get a verification link on your email id and then you have to verify that.

Account Updation:

Here user can upload their personal details like their name, profile images, short bio description.

Privacy: Here user can set up their privacy, means that whom they want to share profile personal details and who going to see their post feed and send them a request and many more.

Follower & Following: Here users can follow you if they like your post and even you can follow others to get notified of their post feed.

Post Feed: Here the post feed will show as per your interest and whom you followed as well as you will get a notification if anything will be posted by your followers.

Notification: Here you will get notified if anyone follows you are any update has been done by your follower or anyone comment in your post.

How much does it cost?

It fully depends on your requirement and what features do you like to build. There is not a fix the budget to build any kind of social media app. Because it required to keep updating their features, database, privacy, servers cost and many more.

But if you would like to start just like Twitter and with their basic functionality then will cost min $49 for mobile app UI (If you would like to check live demo then you can check live demo or Ionic Social Media app here https://www.ionicfirebaseapp.com/product/demo/ionic-firestore-social-mobile-app) and $99 for backend (you can check live demo of Social media backend here https://www.ionicfirebaseapp.com/products/backend-news-firebase-app) for one time with our Social Media app. Apart from Hosting cost and more feature updates and customized. If you are going with us then you can start in just a few hours of setup and installation. But if you are going with others then you min required 60 days to build a Twitter-like app and it will cost you around min $4000 for those basic features.

Note: The cost is not fixed. It will keep varying on technologies, companies, your requirements, hosting, infrastructure and many more factor depends.

Now if you calculate the total cost with these features and with our app then it will cost you $148 one time no customization. You will get all source code that you can host on your server. The server cost will be varying from $30- $50 initial. It will keep growing as your users and storage growth. If you have no idea about the technologies then you might have to make setup and installation services that might additionally cost around $100. So now the final total cost will come around $300 to start your own social media app like Twitter.

Note: This cost is one time only and with our Social app with the basic functionality those we mentioned above and as you seen a demo on give the source. It might cost more if you need any customization.

Now I said that daily pocket money ads marketing strategies:
Here what we used to suggest to start with, whatever you have the pocket money on a daily basis. Like if you have $10 daily pocket money then put $5 on Facebook and target only your local audience and $5 for YouTube branding ads for your local audience. Make sure you have set location correctly.

Now like that keep rolling on a daily basis. Keep switching paid accounts. First day of your pocket money on Facebook and YouTube then second-day pocket money on Instagram and Twitter, Then third-day pocket money on LinkedIn and Facebook and keep running the cycle for one month and one month of the time period you will see the growth in the user's database.

Once you start getting local users then only try to get out and start expanding your user base.

These is basic steps that help you build your social app and how to start marketing for them. But there a a million ways to share your app and reach out to your users.

Hybrid vs Native

vishal kumar — Sat, 31 Aug 2019 08:16:08 +0000

An introduction to cross-platform hybrid development for architects and app development leaders.

The mobile delivery gap

Back in the early days of mobile, there was really only one way to give
your users the performance and features they expected. You had to
use each platform’s native tool set.

Of course, that came with real and measurable trade offs:
• Building in parallel for each mobile platform
• Managing multiple codebases
• Hiring and retaining highly specialized and

costly native developers Meanwhile, demand for mobile experiences continues to grow exponentially. By 2022, 70% of all enterprise software interactions are expected to occur on mobile devices

Given the time and cost of traditional native development, it’s no surprise that many development teams are struggling to keep up with this demand.

Thankfully, times have changed. As mobile and web technology have evolved, hybrid has emerged as a viable alternative to native. Many are now looking at hybrid development as a way to simplify and speed up app creation. Let’s take a
look at the reasons for this shift.

The choice to go hybrid

The growing adoption of hybrid is evident in a recent Forrester survey that found two-thirds of developers are choosing a cross-platform or web-based approach over native tools. Meanwhile,top brands like MarketWatch, Nationwide, and Southwest Airlines have chosen a hybrid approach over native to power apps for their customers and employees.

The top reasons for making the switch from native to hybrid, based on
independent research and testimonials, are:

Speed
Building for multiple platforms from a single codebase often makes delivering cross-platform apps 2-3x faster than native.
Efficiency
Reduced development times, and the avoided costs of hiring and retaining specialized native talent, can save teams 60% or more compared to native3.
Design & ux consistency
With one codebase running on desktop, mobile, and web, hybrid apps provide better design and UX consistency across channels.
Skillset
Hybrid gives web developers and businesses with in-house web teams the tools to build powerful mobile apps using their existing skills and talent.

Put together, the advantages of hybrid have helped centralized development teams close the gap and better satisfy the demand for mobile apps for customers and internal employees.

What is a hybrid app?
Hybrid apps are native apps. They’re downloaded from the platform’s app store or marketplace and offer the same native features, offline support, and hardware-based performance acceleration as any app built with a native SDK.

The key difference is that hybrid apps are built using open web technologies
like HTML, CSS, and JavaScript, rather than the proprietary or specialized
languages used by iOS, Android, and others. That means anyone with a
modern web developer skill-set can begin building an app using the hybrid
approach.

Hybrid apps run in a full-screen browser, called a webview, that is invisible
to the user. Through customizable native plugins, they can access the native
features of specific mobile devices (such as the camera or touch ID), without
the core code being tied to that device.

That means cross-platform hybrid applications can run on any platform or device, all from a single codebase, while still delivering native performance.

Comparing hybrid vs. native

In the sections that follow, we’ll provide a one-to-one comparison of hybrid vs. native, highlighting the pros and cons of each approach.

It’s important to keep in mind that the decision to choose hybrid or native should be based on the unique goals of your organization, the circumstances of a given project, and composition of your existing development team.

Of course, we’re betting big on the power of the web and the promise and potential of crossplatform hybrid development. But we understand that individual circumstances should drive which route you choose.

Hopefully, this comparison guide will give you some useful tips to help you choose the right approach for your next project. But keep in mind, there’s often plenty of room to accommodate different approaches in a single organization. It’s not always an either-or decision.

Why Hybrid?

Drawbacks of hybrid

Of course, hybrid applications are not without their drawbacks:

system overhead
The use of the webview may introduce a degree of overhead compared to native. The abundance of performance APIs and increasingly powerful hardware have made this less of a factor in recent years, but it’s still something to consider. For most applications, the difference in performance is hardly noticeable. But for 3D games and other performance-intensive applications, a hybrid solution may not be the best choice.

plugin management

Cross-platform solutions like Ionic—as well as React Native and others—are able to access nearly every native feature of a device, like the camera or gyroscope, by using native plugins that unlock native device features and integrations using basic JavaScript. In a hybrid app, open source Cordova and Capacitor plugins are the most popular solution to this problem. The use of these plugins does add complexity to development. Ionic offers a curated library of popular plugins known as Ionic Native, with optional support and maintenance for teams building mission critical apps. Nonetheless, this is a factor to consider.

third-party dependence
Choosing a cross-platform approach means you’re placing trust in the maker of the framework vendor (whether it’s Ionic, React Native, Xamarin, etc.) to keep up with the latest and greatest native features and design patterns of each mobile platform. While Ionic is committed to keeping up with new Android and iOS versions, there’s still a dependency any time you choose something other than the native SDK

Why Native?

Benefits of native development

Native is still the preferred approach for many mobile developers. And there are some good reasons for that. While part of that is based on the legacy of having few viable alternatives, native still has its advantages today.

Performance

Native code is still faster than Javascript and HTML. This matters when developers are looking to build demanding graphical applications such as games and other intensive animation applications. Mobile browsers are coming closer to bridging the gap for these types of intensive applications using WebGL specification; however, native still has the advantage here.

Rich native library

Using native SDKs allows the developer to access the latest features specifically designed for those platforms, without the complexity of dealing with native plugins. This is a great option if you’re already familiar with native tools and languages and don’t want or need an additional layer of abstraction.

No third-party dependencies
By building exclusively with a native SDKs, developers aren’t bound to any third-party to keep up with support, and there’s not as much of a dependency on open source communities like Cordova to keep up with the latest features.

Challenges of native development

Here are the most frequently cited challenges associated with native development:

Longer development cycles

Native apps usually have longer development cycles, especially when building for multiple platforms, which requires two or three different code bases for iOS, Android and desktop. Each platform has its own nuances which require specific changes, updates, and maintenance which bloat the cost of an application and add development time. This creates a lot of iterations within the development process in order to customize and test for each platform, it also reduces your agility to launch your application or push updates.

High development costs
Simply put, developing mobile applications natively can be expensive and time-consuming, mostly driven by the time it takes to build for each platform, along with the cost of hiring and retaining highly specialized native talent.

Limited customization
Creating custom UI components to match your company’s design system or pattern library can be more challenging with native components, because you’re limited to the design patterns supported by each platform. And unlike web components, native components can’t be shared outside of their native platform, so you’ll need to maintain multiple UI libraries.

Native talent hard to find
Finding and hiring iOS and Android developers is difficult, given that less than 7% of all developers are versed in the necessary programming languages. It’s also difficult to repurpose those developers for other projects outside of mobile.

Comparing cross-platform approaches

While the various cross-platform frameworks available today—Ionic, Xamarin, Flutter, and React Native—may appear similar on the surface, there are a lot of differences between them that you’ll realize as you dig in.

To summarize very briefly, Ionic Framework and tooling are all based on open web technologies, from the languages that you use to build Ionic apps (HTML, CSS, JavaScript), to the standardsbased UI components running inside your app. In that sense, when you choose Ionic, you’re really choosing the web—the most time-tested, universal runtime in the world. You build with the web, and we give you the tools and component libraries to help you succeed.

Most of the other frameworks add some level of custom UI rendering to work across platforms. For example, React Native translates your JavaScript code into native code at runtime, and uses the native UI elements provided by iOS and Android. Flutter works with the Dart language and uses its own custom graphics engine to work across devices.

Each approach has its benefits and drawbacks, which typically come down to debates about performance, code sharing, customization, and portability. There’s a lot to cover here, so if you’re interested in learning more, check out our comparison guides: Ionic vs. React Native (https://ionicframework.com/resources/articles/ionic-vs-react-native-a-comparison-guide) and Ionic vs Flutter (https://ionicframework.com/resources/articles/ionic-vs-flutter-comparison-guide).
