  • Google reported a 80% spike of Flutter built apps in Play Store after version 1.20 was released. The number of apps built with Flutter in the Play Store has increased from 50,000 to 90,000 since April 2020.
  • As per Google Trends, Flutter is the leading programming language since February 2021 followed by React Native to develop customized cross-platform mobile apps.
  • Creating a startup mobile app with Flutter is in vogue and why would it not be? Flutter provides mind blowing benefits! Let’s discuss some benefits, shall we?

Benefits Of Building A Mobile App With Flutter

1. Fast development process

Flutter cross-platform application development is a huge buzz creator due to its “Hot Reloading” or “Hot Restart” features. With the help of this feature developers are able to write codes and finish the project development in real-time. As a result, coders increase their productivity and save a lot of valuable time.

2. Utilization of widgets

Flutter integrated apps provide a wide range of widgets including navigation, scrolling, fonts, and icons that are customizable regardless of the screen size. These widgets are easy to customize and make the app development process fast and simple.

3. Single code base for multiple platforms

The reason why Flutter is trending is because of its ‘write-once’ approach. Writing multiple codes for different platforms is no longer significant. Flutter mobile app developers only have to code once and not separately for both operating systems, that is Android and iOS, that is why Flutter is considered by most of the developers. As a result, Flutter makes the app development process as cost–effective as possible.

4. User-friendly interface

Flutter can customize almost anything visible on your startup app. Be it shapes, colors, shadows, clipping or transforming elements, Flutter allows developers to execute everything seamlessly. Hence, it is needless to say that Flutter makes the app development process flexible and simple without adding extra workload.

5. Potential to move beyond smartphones

Flutter allows the creation of serverless apps. Developers can use Google’s firebase support as back end and create serverless startup apps. Flutter provides a quick development cycle to help developers achieve their targeted time frames.

If startup app development companies choose Flutter, then it’s the correct choice made. Flutter eliminates the struggle of time constraint and limited budget faced by startups trying to release apps across multiple platforms. Also, it is a blend of all the best Google ideas and technologies, a mixture which results in the creation of a powerful mobile framework.

Step By Step Guide To Flutter App Development

Step-1: The idea

This one is a cliché but don’t all great applications begin with an out of the box idea? Once you have an idea, you need to conduct a market research and find out your target audience. If you wish to create an app then don’t just begin blindly; instead, dig deep and research the facts, concepts and competitors. It is always important to find out how you are better than your competitors.

Step-2: Flutter for MVP

A minimum viable product or MVP acknowledges business owners to validate their idea, gather feedback, and identify customer’s needs. MVP is useful in avoiding market failure and investing on a product that is not backed up by proper market surveys and research.

Being an open source, Flutter complements MVP development. With Flutter increasing the pace of the development process, the process has become more simplified and efficient. Also, Flutter’s compatibility with Firebase, doesn’t require you to separate backends for building simple MVP. Creating MVP with flutter provides an added benefit of delivery of an intricately designed solution.

Step-3: User interface and user experience

Flutter not only provides us with native performance and hot reload for fast development but also access to beautiful, native components. The Flutter toolkit has opened a gateway to allow for a multitude of UI/UX and, by using its own source code, eliminating platform limitations.

Flutter is becoming an all-platform framework. What about when you want to use your startup app or a smaller or a bigger device? Be it a smartwatch, TV, laptop or smartphone. So, you can build native mobile apps using flutter to provide a wider range of devices that the app can function on.

There is no need to build separate code for a multitude of devices, as Flutter already supports that using a single code-base. There are packages you can rely on which are equipped with native iOS & Android widgets to help your app give a platform-specific look.

Step-4: Development, integration and deployment

Startup mobile app development is a highly interactive process. The process includes- planning, development, coding, testing and reviewing. This is the step where you must look out for a Flutter mobile app company that can develop an android app using Flutter.

Flutter app development cost is typically efficient and scalable in comparison to other cross platform frameworks.

Mobile app development comprises three integral parts that are – backend, API and mobile app front end.

  • Backend: The Backend has the information that the end user cannot see. It includes databases and server-side objects that are important for supporting mobile app functions.
  • Google broke down the share of Flutter developers and maximum work for a startup. Here is all you need to know: 35% work for a startup, 26% are enterprise developers, 19% are self-employed, and 7% work for design agencies.
  • API: Application Programming Interface is a communication method between the app and the backend.
  • Front end: The front end of an application is what the user uses. Mostly an app has an interactive UX that uses APIs and backends in order to manage the data.

The Bottom Line

The current app development market is extremely competitive! In order to make a new app stand out within a limited budget, the product should be extraordinary enough to drive the attention of the crowd.

If you are launching your startup app, Flutter is the platform to choose as it allows you to develop user-friendly apps across multiple platforms in a cost-effective way. Unlike other platforms, Flutter app developers create apps with a smooth UI for their users.
