iTechnolabs-How to Convert Mobile App to Flutter

Flutter, a widely adopted cross-platform mobile app development framework, empowers developers to create stunning, high-performance applications for both Android and iOS platforms. Its exceptional flexibility, remarkable speed, and convenient hot reload feature have captivated the attention of numerous companies, prompting them to migrate their existing mobile apps to Flutter. If you possess an already established mobile app and aspire to seamlessly convert mobile app to Flutter, then this comprehensive and informative guide is precisely what you need. By following the expert insights and practical tips presented here, you can confidently embark on your journey of transforming your mobile app into a Flutter-powered masterpiece. In this tutorial, we will discuss the steps involved in converting an existing mobile app to Flutter.

Step 1: Understand Your Existing App

The first step in converting your mobile app to Flutter is to understand its architecture and structure. Take a look at your source code and analyze how different components interact with each other. This will help you determine which parts of your app can be easily converted to Flutter and which ones may require more effort.

Step 2: Choose the Right Plugins

Flutter offers a wide range of plugins that allow developers to access native device features, such as camera, geolocation, and storage. When converting your mobile app to Flutter, it is important to choose the right plugins that will provide similar functionality as your existing app.

Step 3: Convert Your UI

One of the biggest advantages of Flutter is its beautiful and customizable user interface (UI) components. When converting your mobile app to Flutter, you will need to recreate the UI using Flutter widgets. This may take some time, but once done, you will have a fully responsive and visually appealing UI for both Android and iOS platforms.

Step 4: Migrate Your Business Logic

Along with the UI, you will also need to migrate your business logic to Flutter. This includes all the backend code, such as data fetching, processing, and storage. Since Flutter uses Dart programming language, which is similar to many other popular languages like Java and JavaScript, migrating your business logic should not be too difficult.

Step 5: Test and Debug

Once you have converted your mobile app to Flutter, it is important to thoroughly test and debug your code. Since Flutter allows hot reloading, you can quickly see the changes in real-time and fix any bugs or errors that may occur.

Step 6: Optimize for Performance

One of the key benefits of using Flutter is its high performance. To ensure that your app runs smoothly and efficiently, you may need to make some optimizations, such as reducing unnecessary code or using asynchronous programming techniques. This will help improve your app’s overall performance and provide a better user experience.

Benefits of the Flutter for website

In addition to being able to convert your mobile app to Flutter, there are other benefits of using Flutter for your website. Firstly, it allows for faster development time as you can use the same codebase for both your mobile app and website. This also means easier maintenance and updates as any changes made will reflect on both platforms.

Additionally, Flutter offers a more consistent user experience as it uses the same UI elements for both Android and iOS. This helps to maintain your brand identity and creates a seamless transition for users between platforms.

Furthermore, Flutter’s high performance can help improve website loading times, leading to better user engagement and potentially higher conversion rates. It also allows for easier integration with third-party services and plugins, making it more versatile for your website’s needs.

  • Faster development time: Flutter’s code sharing capability allows developers to leverage a single codebase for both mobile apps and websites. This not only saves time but also eliminates the need for separate development processes, resulting in accelerated development timelines.
  • Easier maintenance and updates: With Flutter, any changes made in the codebase are automatically reflected on both platforms, ensuring consistent updates and making maintenance a breeze. This streamlined approach simplifies the overall development lifecycle and reduces the effort required for ongoing maintenance.
  • Consistent User Experience: By utilizing the same UI elements for both Android and iOS platforms, Flutter delivers a seamless and consistent user experience. This cohesive design language across platforms enhances user satisfaction, promotes brand recognition, and fosters a sense of familiarity for users across different devices.
  • High performance: Flutter’s inherent performance optimizations contribute to faster website loading times. By minimizing rendering and processing overhead, Flutter maximizes the efficiency of web applications, leading to improved user engagement and potentially higher conversion rates.
  • Versatility: Flutter’s extensive support for third-party services and plugins enables easy integration with various functionalities. This versatility empowers developers to customize and tailor their websites to meet specific requirements, ensuring a robust and comprehensive solution for diverse business needs.

How Much Does it Cost to Convert Your Mobile App to Flutter?

Converting an existing mobile application to Flutter, a popular open-source mobile application development framework, can vary in cost based on several factors. These include the complexity of the app, its current technology stack, and the required features and functionalities in the redesigned app. For a basic app with minimal features, the cost to convert mobile app to flutter can cost around $5,000 to $10,000. For applications with moderate complexity and more advanced features, prices can range from $10,000 to $25,000. However, for complex apps with extensive features, third-party integrations, and high-performance requirements, the cost may escalate to $30,000 or more. It is always advisable to consult with professional developers or a development company to get an accurate quote tailored to your specific app needs.

The cost of converting a mobile app to Flutter can vary significantly based on various factors such as the complexity and scale of the original app, the number of features and functionalities to be migrated, the level of customization required, and the overall project timeline. It also depends on the development team’s expertise and experience in working with Flutter technology. Therefore, it is important to carefully assess the specific requirements and consult with professionals to get an accurate estimate of the cost involved in the migration process.  However, here are some factors that may impact the overall cost:

  • Development Team – Hiring experienced developers who have expertise in both native platforms and Flutter can be costly. It is essential to ensure that the team is well-versed in Flutter’s best practices and has a strong understanding of both Android and iOS development. Additionally, having developers with prior experience in similar projects or with a deep understanding of your specific industry can bring added value and efficiency to the conversion process.
  • App Features – The complexity of the app features can also influence the cost. Apps with more advanced features may require additional development time, leading to higher costs. For example, if your app requires complex functionalities such as real-time data synchronization, payment gateways, or integration with third-party APIs, it will require more time and effort to implement and test these features in the Flutter framework.
  • User Interface (UI) Design – If you plan to revamp the UI design along with converting your mobile app to Flutter, it will add an extra cost. Developers may need to adapt existing designs to fit Flutter’s layout framework, which can require additional effort and resources. Additionally, if you want to create a highly polished and visually appealing user interface, it may involve graphic designers or UI specialists, which can also impact the overall cost.
  • Timeframe – The time allocated for the conversion process can impact the costs involved. A shorter timeline may require more developers working simultaneously, leading to higher costs. On the other hand, a longer timeframe allows for a more gradual and controlled conversion process, potentially reducing the overall cost. It is important to consider the trade-off between time and cost when planning the conversion project.
  • Testing and Debugging – As with any software development project, testing and debugging are crucial to ensure a high-quality app. These processes can add to the overall cost, depending on the complexity of the app and the number of bugs encountered. Thorough testing across different devices, operating systems, and scenarios is necessary to ensure a seamless user experience and to identify and fix any issues before the app is launched.
  • Maintenance – Once your mobile app is converted to Flutter, it will require ongoing maintenance and updates. This aspect should also be considered when determining the total cost of conversion. Regular updates to support new OS versions, security patches, bug fixes, and performance optimizations are necessary to keep the app running smoothly and to provide a satisfactory user experience. The cost of maintenance will depend on the size and complexity of the app, as well as the frequency and scope of updates required.
