Overview
The official Dart project benchmark harness provides a standardized framework for writing and running performance benchmarks in Dart. It enables developers to measure execution time, memory usage, and other performance metrics with precision across multiple platforms. Designed for integration into Dart and Flutter projects, it supports consistent benchmarking on Android, iOS, Web, macOS, Windows, and Linux. The harness simplifies the creation of repeatable, reliable tests that help identify performance regressions and optimize code. It is particularly useful for core library development and performance-sensitive applications.
