Integrating React Native into an Existing Flutter Application

Callstack explores one of mobile dev's wildest experiments: embedding React Native inside a Flutter app. Yes, you read that right.

This article from Callstack tackles the unconventional brownfield scenario of integrating React Native into an existing Flutter application. While most brownfield discussions focus on adding React Native to native iOS/Android apps, this explores the technical feasibility and tradeoffs of mixing two cross-platform frameworks.

Key Takeaways

• Demonstrates React Native can technically run inside Flutter apps
• Requires native bridge setup on both iOS and Android platforms
• Adds significant complexity with two JavaScript engines and rendering systems
• Better suited for gradual migration than long term dual framework strategy

The article reveals surprising performance implications when two cross-platform frameworks try to coexist in the same app.
