benchmark_harness 2.2.3

The official Dart project benchmark harness.

2.2.3

• Require Dart 3.2.
• Add PerfBenchmarkBase class which runs the 'perf stat' command from linux-tools on a benchmark and reports metrics from the hardware performance counters and the iteration count, as well as the run time measurement reported by BenchmarkBase.

2.2.2

• Added package topics to the pubspec file.
• Require Dart 2.19.

2.2.1

• Improve convergence speed of BenchmarkBase measuring algorithm by allowing some degree of measuring jitter.

2.2.0

• Change measuring algorithm in BenchmarkBase to avoid calling stopwatch methods repeatedly in the measuring loop. This makes measurement work better for run methods which are small themselves.

2.1.0

• Add AsyncBenchmarkBase.

2.0.0

• Stable null safety release.

2.0.0-nullsafety.0

• Opt in to null safety.

1.0.6

• Require at least Dart 2.1.

1.0.5

• Updates to support Dart 2.
