Sharing pricing and validation logic across iOS and Android
How Kotlin Multiplatform could keep critical rules identical on both platforms.
Illustrative example. This describes a common mobile challenge and an approach Dragonfly consultants could take. It is not a client engagement and does not report real results.
The challenge
Pricing and eligibility rules were implemented twice, and small differences between the apps caused support tickets and audit questions.
The approach
- Identify the rules that must match exactly, and move them into a shared Kotlin module.
- Keep screens, permissions and platform integrations native on each side.
- Write one shared test suite that runs against the rules on both platforms.
- Start with one module and expand only after the first one is stable in production.
What success would look like
One definition of each critical rule, fewer cross-platform discrepancies, and faster updates when rules change.
