Jun 1, 2025June 2025 monthly summary for noncelab/coconut_wallet focused on reliability, performance, and data integrity. Key lifecycle stabilization work ensured the isolate lifecycle and wallet subscription flow behave consistently across app exit, re-entry, and wallet deletion. Network connectivity and wallet synchronization were overhauled for improved resilience, with a transition to stream-based state management and ChangeNotifierProvider wiring for robust re-connect and synchronization handling. Data modeling and migrations were modernized, including RealmSchema additions, centralized RealmIdService, a 4-byte hash function replacement for Object.hash, and enhanced migration history. UI performance optimizations reduced unnecessary rebuilds and improved rendering for UTXO, address, and BIP39 lists, while maintaining correct display and behavior. Notifier and update flows were strengthened to ensure balances refresh after wallet add/remove and to emit notifications after transaction list changes. At a higher level, these changes improve reliability, developer velocity, and data integrity with measurable business value across stability, performance, and correctness.
