Today, I'm excited to announce Polly Dart - a comprehensive resilience and transient-fault-handling library for Dart applications. Inspired by the battle-tested .NET Polly library, Polly Dart brings enterprise-grade resilience patterns to the Dart ecosystem.

Why Resilience Matters More Than Ever​

In our interconnected world, applications depend on numerous external services, APIs, databases, and resources. Network hiccups, service outages, and resource contention are not exceptions—they're inevitable realities. The question isn't whether your application will encounter failures, but how gracefully it will handle them.

Consider these common scenarios:

• A mobile app loses network connectivity while syncing data
• A Flutter web app calls an API that's temporarily overwhelmed
• A Dart server application hits database connection limits
• A microservice times out due to unexpected load

Without proper resilience strategies, these situations lead to poor user experiences, data loss, and system instability.
