Bridging Native and Flutter: Complete Deep Link Handling Solution

This article addresses a critical pain point in Flutter development—handling deep links that behave inconsistently when the app is closed versus running.

This pattern is essential for production apps requiring URL-based navigation, referral programs, and seamless user acquisition flows.
