core_model 0.1.1

Shared primitives with no Flutter dependency: an ownership lease, a cancellation token, a retry backoff, an injectable clock and staged-initialization timings.

Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

0.1.1 - 2026-09-20

Added

• Clock and SystemClock: the current instant as an injected dependency, so a caller can be handed a clock that reports a time the system clock has not reached. SystemClock is the only DateTime.now() behind the interface.
• DiTimings and DiStepTiming: how long each step of a staged initialization took, recorded in order and readable after the run, including after it failed. DiStepTiming is a typedef over ({String name, Duration duration}), so a caller that already speaks in records needs no conversion.
• A library doc on core_model.dart, which is the package's dartdoc landing page.

Changed

• Dart SDK constraint raised to ^3.13.4.
• Formatter settings dropped from analysis_options.yaml; lints_tool 1.1.1 supplies them.
• README.md and the package description cover the whole surface, and README.md installs from pub.dev rather than by git ref.

0.1.0 - 2026-09-04

Added

• First released version: Lease, CancelToken, RetryBackoff and RetryNotifier with their tests; Guid, IDeviceInfo and a platform-neutral VoidCallback.

Changed

• Versioned 0.1.0: the API is young and may still move. The build number a Flutter template writes means nothing on a library and is gone.
