This guide provides general planning information. Product, technical, legal and tax requirements should be verified for your own business.
The shared-code promise and its limits
Both Flutter and React Native can share substantial application code across Android and iOS. Neither removes platform work: permissions, notifications, background behavior, signing and store review still differ.
The right comparison begins with the riskiest requirement, such as Bluetooth hardware, payment SDKs, background location or offline synchronization. Validate that path with a small technical prototype.
When Flutter can be a strong fit
Flutter offers a consistent rendering and component system, which can suit teams that want tight control over a custom interface across platforms. Dart becomes a deliberate shared language for the mobile product.
- Highly customized, consistent UI
- A team comfortable adopting Dart
- Shared application code across mobile targets
- Early validation of required plugins
When React Native or Expo can be a strong fit
React Native can suit organizations already working with React and TypeScript. Expo can simplify parts of development and release management, while development builds support capabilities beyond the basic Expo Go environment.
- Existing React and TypeScript experience
- Reuse of business logic and tooling
- Compatible native modules and SDKs
- A release workflow tested with signed builds
Make the decision with a proof
List the three requirements most likely to fail, then build a short proof on representative devices. Compare developer experience, build reliability and the actual integration—not synthetic benchmark claims.
Also consider who will maintain the app, how often platform updates will be adopted and whether native specialists are available when a plugin does not cover the requirement.
