Platform Strategy
Native Android & iOS vs Flutter App Development
There is no universal best technology for every mobile product. Platform strategy should follow the actual requirements of the application.
Native Mobile Development
Native development can be appropriate when an application requires deeper platform-specific capabilities, highly specialized device functionality, or separate platform optimization.
Platform-specific development
Native APIs
Platform-specific UI behavior
Device integration
Separate Android and iOS projects
Flutter Development
Flutter can be effective when a product needs Android and iOS support with shared product logic and a consistent cross-platform interface.
