The Benefits of Rewriting Your App with Flutter

As a startup founder, you're always looking for ways to maximize efficiency, reduce costs, and stay ahead of the competition. The technology stack you choose can significantly impact your ability to achieve these goals. If you're currently maintaining separate native iOS and Android applications, it might be time to consider migrating to Flutter.

Why should you consider rewriting the application to Flutter?

Here’s why it might be the right choice for your project:

Addressing Legacy Code

Legacy code can become a major roadblock as your application evolves. Over time, code written by different developers can become overly complex, difficult to maintain, and prone to security vulnerabilities. This complexity can slow down your development cycles, making it harder to implement new features quickly. Migrating to Flutter allows you to modernize your codebase with a framework that’s actively supported by a vibrant community, reducing maintenance headaches and improving overall performance.

Lowering Operational Costs

Maintaining separate codebases for iOS and Android is costly. It requires two teams, two sets of processes, and double the effort for testing and quality assurance. Flutter’s single codebase approach can significantly reduce your operational costs. By consolidating your development efforts into one team, you can cut down on labor costs, accelerate time-to-market, and ensure a consistent user experience across both platforms.

Overcoming Competence Asymmetry

When working with separate teams for iOS and Android, differences in experience and knowledge can lead to inconsistencies in your app’s performance and user experience. Flutter mitigates this issue by allowing one team to manage the codebase for both platforms, ensuring that everyone has the same level of understanding and expertise.

Simplifying Team Management

Managing two separate development teams comes with its own set of challenges, including communication gaps, coordination issues, and the potential for knowledge silos. Flutter streamlines team management by enabling a single team to handle both iOS and Android development, reducing complexity and improving collaboration.

Eliminating Code Desynchronization

One of the common challenges in maintaining separate codebases is code desynchronization, where features are developed at different paces or in different ways across platforms. This can lead to inconsistencies and increased maintenance efforts. With Flutter, you write code once and deploy it across both platforms, ensuring feature parity and a seamless user experience.

How Flutter Can Help

When considering a migration to Flutter, you have two main options: a staged migration or a full rewrite. The decision depends on your specific needs and objectives.

• Staged Migration: Flutter provides a powerful tool called "Add-to-App" that lets you seamlessly integrate Flutter modules into your existing native application. Thanks to that you can rewrite to Flutter one feature, one flow, or even implement a new feature straight in Flutter and then use it in native code. You can even migrate just the business logic that's shared between platforms. This approach ensures a smooth user experience as the transition to Flutter happens behind the scenes and is seamless for users. Additionally, Flutter offers "Platform Channels" to facilitate communication between native and Flutter code. This two-way communication allows you to leverage existing native code while migrating to Flutter. Essentially, Flutter and your native code can coexist and work together harmoniously.
• Full Rewrite: If you’re looking to fully embrace Flutter, you can opt for a complete rewrite of your app. While this requires a more significant investment upfront, it can result in a cleaner, more efficient codebase in the long run.

Addressing Common Concerns

Migrating to a new technology can be daunting, but it’s important to weigh the potential benefits against the challenges. Here are some common concerns and how Flutter addresses them:

• No Full Commitment Required: The "Add-to-App" feature allows you to test the waters without fully committing. You can gradually integrate Flutter into your existing app and reassess as needed.
• Continuous Development: Staged migration means you can continue developing your app while migrating, minimizing disruptions to your development process.
• Data Continuity: Switching to Flutter won’t affect your data storage or analytics processes. Flutter supports seamless data migration, ensuring that all your important information remains intact.
• UI Consistency: Flutter allows for the creation of custom components and the use of native design elements, ensuring that your app’s look and feel remain consistent across platforms.
• Long-Term Support: Google’s commitment to Flutter is evident in its extensive roadmap and ongoing improvements, particularly in areas like web development. You can be confident that Flutter will remain a viable, well-supported option for years to come.
