Migrating native apps to Flutter

Developing mobile apps with Flutter is a good choice for projects that start from scratch. But what about those enterprises that already run native apps? How much would the migration costs be? Determining the migration cost depends on factors such as the characteristics of native code and business situation. Let’s take a look at some of the important factors for migration costs.

Rewrite the code

The most efficient way to migrate native apps to Flutter is to write the new code in Dart. If your native source code is well-structured, rewriting the code will only take a small fraction of the time. When calculating the initial cost, consider the effort for the first release and add the sum of all efforts for change requests.

Business situation

The main factor to calculate the cost is your business situation. Let’s assume that you plan to run your business as usual for the next 1–2 years. In this case, migrating your two native apps to a single code base will reduce maintenance costs by almost half, since there is only one code to maintain. So, your estimated cost savings are about half of what it costs to run your two native apps today.

Project set-up

If your previous calculations have shown that a flutter migration could be good, there are still many things that can be a problem. Here are some of the things that can help you avoid the biggest mistakes: Mixed development teams, continuous delivery, and testing, and architecture and planning sprint.
