Migrating from React Native to Flutter: Challenges and Considerations

Mobile app development has grown in popularity in the last few years especially due to frameworks such as React Native and Flutter. Facebook’s React Native has been a top choice among developers because of its cross-platform features and flexibility in creating applications using JavaScript. But, Google’s Flutter appears as a serious challenger with its excellent performance and native-like user interfaces (UI). As technology advances, developers may consider migrating from React Native to Flutter. In this article, we will examine the challenges and considerations that come with upgrading from React Native to Flutter.

Understanding React Native and Flutter:

Before we get started with the migration process, let’s review the core differences between Flutter vs React Native. React Native communicates with native components through a bridge, helping developers to reuse the majority of the code across platforms. Flutter, on the other hand, builds expressive UIs without depending on the platform’s native components by using a compiled programming language, Dart, and a custom rendering engine, thus minimizing reliance on the platform’s native components.

Benefits of Migrating to Flutter:

Considering the initial cost necessary for migration, Flutter provides various benefits that make the switch beneficial.


The rendering engine of Flutter allows for smooth and rapid animations, resulting in improved overall performance as compared to React Native.

Consistent User Interface: 

Flutter offers a collection of pre-designed widgets that give a uniform UI experience across platforms, ensuring your app appears natural on both Android and iOS.

Fast Reload:

Flutter’s fast reload functionality lets developers view changes in real-time during development, which speeds up the debugging and testing process.

Access to Native Features:

Despite React Native, which relies on third-party libraries for native features, Flutter provides direct access to platform-specific functionalities via plugins.

Challenges in Migration:

Moving from React Native to Flutter is not without difficulties. Developers must be aware of these challenges and plan accordingly.

Learning Curve:

Developers who are used to working with JavaScript in React Native may find it difficult to switch to Dart, Flutter’s core language. But with sufficient work, the learning curve may be overcome.

Widget-based Architecture:

Flutter has a widget-based architecture, while React Native is component-based. The move to widgets requires reconsidering the UI structure and design patterns.

Third-party Libraries:

The React Native ecosystem is rich in third-party libraries, some of which may not have direct analogs in the Flutter community. Migrating could involve looking for other options or developing custom widgets.

Platform-specific Code:

If your React Native app mostly depends on platform-specific code, rewriting this logic for Flutter might be time-consuming.

How to Preparing for the Migration:

Comprehensive planning is required for a successful migration. The following are some important steps to consider before beginning the migration process.

Evaluate the App: 

Analyze your current React Native app to understand its architecture, components, and dependencies. Determine potential challenges and locations that require major improvements.

Build a Migration Plan:

Create a detailed migration strategy that describes the necessary stages, resources, and dates for making a transition.

Training the Team: 

Make sure your development employees are well-versed in Flutter and Dart to ensure a smooth migration. Consider offering workshops or online courses.

Set Up Version Control:

Make use of version control tools such as Git to track changes during migration, making it easy to roll back if necessary.

Steps to Migrating from React Native to Flutter:

Now that we’ve prepared for the migration, let’s get into the process.

Step 1: Create a New Flutter Project

Start by making a new Flutter project. This will act as the basis of your transferred app.

Step 2: Partial Migration

Consider a phased migration technique instead of transferring the entire app at once. Begin with migrating small, self-contained modules and slowly progress to more complex components.

Step 3: Rewriting UI Components

While Flutter has a different UI design, you’ll need to rebuild UI components using Flutter widgets. This requires modifying the current codebase.

Step 4: Migrating Business Logic

Transfer the React Native business logic to Dart. While the functionality is the same, the implementation may vary.

Step 5: Testing 

Test the transferred modules thoroughly to confirm that they work as expected. Use automated testing to detect potential regressions.

Step 6: Integration

After successfully migrating the modules, merge them into the main Flutter project and retest the entire app.

Post-Migration Considerations:

Upon the completion of the transfer, there are a few more considerations for ensuring a smooth transition.

Performance Optimization: 

Using Flutter’s performance features to optimize the app for users to have a smooth experience.

Code Review:

Perform an in-depth code review to discover possible errors, inconsistencies, or poor code.

User Feedback:

Collect customer feedback and fix any issues that arise after the transfer. User satisfaction is critical to your app’s success.


Migrating from React Native to Flutter may be a difficult but rewarding experience for developers. You can make a well-informed decision about whether the move is appropriate for your project if you understand the benefits, challenges, and considerations associated. Through good planning, preparation, and execution, the migration process may result in an excellent performance, a consistent user interface, and an improved app development experience. As technology grows, the software community will surely benefit from keeping flexible and open to explore new frameworks.
