Quiver is a set of utility libraries for Dart that complements the standard library with helpers for async streams, caching, collections, iteration, strings, patterns, time, and testing. It is published on pub.dev as the quiver package and maintained by Google.

Use cases

  • use an LRU cache or multimap in Dart
  • split or merge Dart streams
  • fake async and time in Dart tests
  • precondition checks like Guava Preconditions in Dart
  • bidirectional map in Dart
  • countdown timer or metronome stream in Flutter

When to avoid

  • you only need features now covered natively by modern Dart (nullable types, built-in collection methods)
  • you need a framework or full application toolkit rather than small utilities
  • you want a package with frequent new features; releases are infrequent
