Release Notes

flutter-it/get_it (get_it)

v9.2.1

• Added AI skill files in skills/ directory for AI coding assistants
• Added AI-Assisted Development section to README

v9.2.0

• allReady() now caches its Future and returns the same instance on repeated calls
  • Cache is automatically invalidated when new async singletons are registered
  • This enables watch_it to detect when async registrations change (e.g., after pushNewScope)
• Fixed: pending async singletons now complete their ready completer when removed via unregister() or scope reset, allowing allReady() to complete properly

v9.1.1

• Updated example project

v9.1.0

• Added DevTools extension for visualizing and inspecting GetIt registrations
  • View all registered objects with their type, scope, registration mode, and state
  • See instance details via toString() output for created instances
  • Manual refresh button to update the registration list
  • Requires debugEventsEnabled = true to be set on GetIt instance
  • See README for setup instructions

v9.0.5

• Use absolute GitHub URL for logo in README

v9.0.4

• Fixed screenshots description to match working 9.0.1 format

v9.0.3

• Fixed logo display on pub.dev by using relative path

v9.0.2

• Fixed button sizing in README for pub.dev display

v9.0.1

• Fixed linter error (missing trailing comma in test file)

v9.0.0

• BREAKING: Disposal order now always follows strict LIFO (Last-In-First-Out) based on registration order
  • Previously, disposal order was based on the order objects appeared in internal hash maps, which was unpredictable when mixing named and unnamed registrations
  • Now all disposals are sorted by registrationNumber (a sequential counter assigned during registration) ensuring true LIFO order
  • The strictDisposalOrder parameter has been removed from reset(), resetScope(), popScope(), popScopesTill(), and dropScope() methods
  • Performance impact is minimal: ~8% overhead for 10,000 registrations (approximately 2-3ms), negligible for typical applications
  • This change ensures correctness and predictability in dependency cleanup, which is more important than the minor performance cost
  • Impact on existing apps: If your app's behavior relies on the previous imperfect reverse disposal order, there is likely a design issue in your dependency structure that should be addressed
• Fixed bug in registerCachedFactoryParamAsync where calling getAsync would fail with null error because it was checking the wrong function parameter (sync creationFunctionParam instead of asyncCreationFunctionParam)
