What is Flutter?

In the last few years of this decade, we have seen a lot of app startups emerging from all across the globe. With the rise in technology and the availability of smartphones, many startups find it easy to connect with users and clients via apps. The app market has also grown in the last few years and is expected to grow exponentially in the coming decade. The app development market has also been on a rise and has allowed countless app developers to exhibit their skills and find a suitable job. With this shift into apps, much development, and research have been done to deliver the best and to make the app development process faster and much simpler. Apps can be broadly categorized as: 

1. iOS Apps:

These apps are made for Apple devices and wear. iOS apps are made using the Swift language. The iOS apps have an extension of .ipa. 

2. Android Apps:

These apps are made for android devices and wear. Android apps are made using Java and Kotlin, with an extension of .apk. Many app developers who had to work in a cross-platform work environment, and are responsible for the development of both android and iOS apps, found it a difficult and lengthy process to develop apps for both platforms. The major problems encountered by companies and developers were:

• No Cross-Platform Dependency: iOS and Android apps work very differently internally, so the developers had to redesign and reconfigure the same content for individual platforms.
• Time Constraints: Making a professional app, from coding to designing, requires a lot of time. Companies usually set a time limit by which the app should be ready to be launched into the market. Those developers who had to work on both these platforms often found time limit issues, and the efficiency and quality of work degraded.
• More Employees: This problem was encountered by companies. Since they have to develop an app for both platforms, a greater number of app developers knowing about the individual platform had to be hired.
• Development Cost: Since the app has to be made individually for both platforms, the cost of development will increase, as more developers will be required.

Since the launch of Flutter in May 2017, it has resolved many of the existing problems in the app development industry. Flutter is a powerful technology, or we can say a tool backed by Dart language packed with a powerful mobile framework that can be used in both iOS and Android applications. Flutter is often used with DART, which is an object-oriented programming language by Google. The flutter development tools come with a graphics library and material design, and the Cupertino design allows faster operations of the app and also gives the app a stunning look, irrespective of its operating platform! The biggest advantage of flutter is that it can be used to create cross-platform apps. Using flutter, one can create iOS apps, Android apps, Websites, and much cross-platform software in just one go, there is no need to write code for different platforms.

Why is Flutter a boon for Startups and Companies?

The main goal of any company is to acquire more customers, and in the case of app startups, their main concern is to increase user acquisition, irrespective of the platform (iOS or Android). Many startups that either provide their services via an app or startups which are completely dependent on app, must decide whether they would like to have the app in the native format or would have an app that could be used irrespective of the operating platform. Apps that are of native format are required to be developed individually for every platform. The majority of the startups require an app that could work on different mobile platforms in one go, and so the role of flutter comes into the picture.

Features of flutter 

Flutter structure offers the accompanying elements to designers:

1.  Present day and receptive structure.
2.  Utilizes Dart programming language, and it is extremely simple to learn.
3.  Quick turn of events.
4.  Delightful and liquid UIs.
5.  Colossal gadget list.
6.  Runs same UI for numerous stages.
7.  Superior execution application
8.  Fast and responsive layout.
9.  Easy connection of back-end and asynchronization.

Advantages

1. Cross-platform Operations: Apps made with flutter can be operated on both the platform (iOS and Android). There is no need for reconfiguration and redesigning. 

2. Less Need of Developers: This can be advantageous for the companies, as they require a smaller number of developers and the app can also work on both the platforms. 

3. Less Development Cost: Since there are a smaller number of developers needed, the cost incurred for the development of the app also reduces. 

4. Time Constraint: The time required to launch the app into the market, also reduces as only a single app has to be made, which would work independently of the platform. 

5. Powerful Design: Flutter mobile framework is the latest in the market, and this helps to create a very powerful app design with minimum efforts.

Flutter accompanies delightful and adjustable gadgets for superior execution and
extraordinary versatile application. It satisfies every one of the custom necessities and prerequisites. Other than
these, Ripple offers a lot more benefits, as referenced beneath:

1.  Dart has a huge storehouse of programming bundles which lets you expand the
   capacities of your application.
2.  Engineers need to compose only a solitary code base for the two applications (both Android
   what’s more, iOS stages). Ripple may to be stretched out to other stage also from here on out.
3.  Vacillate needs lesser testing. Due to its single code base, it is adequate on the off chance that we compose
   mechanized tests once for both the stages.
4.  Ripple’s straightforwardness makes it a decent contender for quick turn of events. Its customization
   capacity and extensibility makes it much more remarkable.
5.  With Ripple, designers has full command over the gadgets and its format.
6.  Ripple offers extraordinary designer instruments, with astounding hot reload.
   

Disadvantages

• Apps made via flutter work a bit slower on older devices, as the code interpreter is designed to work with native code, in older devices. Many studies show that the performance of apps made with flutter is directly dependent on the processor used. 
• Flutter is a cross-platform tool, so the apps developed using flutter do not give the feel of a native app, the design and; working is a bit different, although the required operation remains the same. Native apps are designed to work for a specific platform, while apps made via flutter are designed to work on cross-platform devices, so the app has to be at a common position to work on both the platforms. 
• Despite the disadvantages, many companies have switched to flutter to develop apps, and the requirement of developers having experience in flutter is appreciated via applying for a job. On the other hand, flutter is also being improved so that the disadvantages faced by developers, can be reduced. Many other technologies, such as Firebase, and Node.js are extending their support to flutter, and this is helping flutter to build a strong and reliable ecosystem. Many companies such as Alibaba, Geek ants, Tencent, ByteDance, BMW have started to use flutter. For all those app developers who wish to work in the app development industry, they should first learn the native languages for app development and then should learn Flutter. Since the demand for flutter is growing exponentially, the demand for native app developers will decrease in the coming years. So having experience in Flutter is mandatory, if anyone wishes to work in the app development industry in the coming years.

Disadvantages of flutter

In spite of its many benefits, vacillate has the accompanying downsides in it:

1.  However, since it is coded in Dart language, a designer needs to learn a new dialect, although it is not difficult to learn.
2.  Current system attempts to isolate rationale and UI however much as could be expected at the same time, in Shudder,
   UI and rationale are intermixed. We can beat this utilizing savvy coding and
   utilizing significant level module to isolate UI and rationale.
3.  Ripple is one more system to make versatile application. Designers are having
   a tough time in picking the right improvement devices in immensely populated portion
