How to create a flutter mobile application?

Mobile application development has expanded extensively over the last few years. As we know that the world is getting digitalized that’s why more and more people are using mobile applications even for their daily routine works. The requirement for mobile applications is rising day by day.
If we read the old stats about mobile applications then lonely mobile applications have produced about $190 billion profit through app stores, in-app purchases, and advertisements. Here the story is still not finished it is estimated that the mobile applications will generate about $500 billion by the end of 2022.

What is flutter?

Flutter is an open-source SDK (Software Development Kit) utilized for developing attractive, natively organized apps for mobile phones, web, and desktops with a solitary codebase.
Let us understand what the above paragraph tells us. Assume that the developer has developed an astonishing application and the application is getting a good response but it is only supported on the iOS platform. Now the developer has spent a number of hours learning Android so that more and more customers can get the application benefit but after doing this developer gets to know that the application should support all the android screen resolutions which will ultimately increase their work. That’s where flutter helps the developers as it provides a single codebase through which the developer does not need to write the code for different platforms again and again.
The flutter SDK is maintained by Google. The flutter is a toolkit that is designed in order to develop applications for various platforms, screens, and devices, permitting cross-stage development.
Various flutter mobile app development tools are free software technologies that consist of various plugins and widgets that the designers can leverage to develop mobile and extremely customizable apps for the business organization. The solitary codebase available in these SDKs is very well integrated that it increases the app’s adaptability and performance.

How to create a flutter mobile application?

• Research and analysis
The very first and the most important step in flutter mobile app development is to find which application should be developed. If you are not having any idea which app to be developed then you must do research and analysis about what type of problems are being faced by the customers recently and what are the best ways in order to solve them. You need to completely analyze this as it will be a basic and very important component for your application which will ultimately help you decide which type of application should be developed and how it will be going to help the customers in their problem.
• Conceptualization and Brainstorming
This will be the second step for your flutter app development. At this point, your idea for an app starts to take shape and turns into a real project. Brainstorming starts with classifying user cases, capturing detailed functional requirements. Once the needs have been identified, the preparation of the product roadmap begins. The roadmap will include the grouping of project requirements into delivery stages. If you have time or cost issues, choose a Minimum Viable Product (MVP) and create your MVP in Flutter for your initial launch. Part of this phase also includes a detailed study of your competitor's application, which will help you determine what features are missing in their application so that you can include them in your idea to stand out.
• Layout and UI/UX
The next step involves the wireframing of the application in order to acknowledge upcoming functionalities. Wireframes are theoretical layouts, also referred to as low-fidelity mockups. At this point, we start developing screens and allocating each task and data. The app development idea is still not implemented. Before starting the app development we should make a blueprint of our website and make changes accordingly so that in the future developer doesn’t need to face any problems in changing the codes again and again. With the layout, the main objective is to focus on the user experience and the beautifulness of the application.
After this, we start developing UI/UX whose main motive is developing a flawless design with a glossy look. This is the time when the app starts taking its form. The blueprint of the application is designed by the designer visioning the final result or we can say how the application will look after its completion. It also mentions that how it will be interacting, the flow of the application, and many more.
• Development
This is a step at which the design is executed into the coding language or the design is translated into computer understandable language. At this, the work is split up into segments so that it will be clear for the developer to do work easily and effectively, and also he does not get confused about the work. This step is the longest step in the development cycle. Each cycle comprises four steps- Planning, Development, Testing, and Review.
Each and every mobile application development project is created through three parts:
Backend
The backend comprises databases and the server-side gadgets necessary for maintaining mobile applications. The backend for your mobile application reserves and classifies the data which the ultimate user won’t be able to see.
2. API
An Application Programming Interface (API) acts as a mediator between the application and the backend.
3. Frontend
The front end is that part of the application which the end-user client will experience. Almost all the applications comprise of connected client experience that utilizes APIs and backend to information management.
• Beta release
At FlutterDevs, we are tracking the beta version of the app, in addition to or instead of newsgroups. The beta version is intended for a group of testers to use the app in the real world. They use the application as if it were launched but in smaller numbers. Plus, beta testing is a great time to see how the application performs on various devices, operating systems, locations, and network conditions.
• Deployment
The application is now ready to be launched. There are mainly two elements of deploying the application in the world. The first element states that deploying your application API into producing an environment that is adaptable. The other element is launching your application on Google PlayStore and Apple AppStore. When the application is launched on Google PlayStore the application will available to the user at the day end only but for AppStore, there are certain rules and policies which have to be followed that is why launching your application and reviewing could take a few days or several weeks for apple store which is dependable on the condition of the application and how much the application has followed the guidelines of iOS development guidelines.
• Maintenance
When the deployment step has taken place in the production environment, the maintenance of the product should be done which means that if any problem arises in the application then it should be fixed by the developers. Also, the updates regarding the applications should be done in a timely otherwise the user may get bored with the application they will stop utilizing the product. In order to retain the customer developers should come up with new features and updates.

Why flutter is tremendously utilized for mobile app development?

The main objective of flutter is to clarify and expeditiously create cross-stage mobile applications while preserving the native design and also visually harmonious among stages. Flutter mobile app development properties allow the developers to create native applications by utilizing custom widgets. The latest update of Flutter that is Flutter 2.0 has pleased the developers from operating on different stages for the same project. Recently the flutter is focused mainly on providing a better experience than targeting a particular platform while developing mobile applications.
Flutter provides an influential design experience with huge systematized custom widgets over platforms that are convenient to develop a native-like experience for business requirements. As a cross-platform app development tool, flutter provides a cost and time-effective remedy which allows the developers to gain effectiveness in the development process. Flutter utilizes dart as its programming language which is simple to understand and learn. At the present time flutter is utilized by 39% of the developers all over the world and it has now become the second most utilized framework for cross-platform app development.
