devtools_profiler_core 0.3.0

Pure-Dart profiling backend for DevTools-inspired Dart and Flutter CLI and MCP workflows.

Changelog

0.3.0

• Added inherited-stdio process IO mode for terminal UI and alternate-screen profiling targets.
• Added deterministic VM-service discovery for inherited-stdio Dart launches and Flutter run launches.
• Added optional interrupt signal handling so hosts can finalize available diagnostics before stopping an interrupted target.
• Reduced shutdown polling overhead by backing off exit-pause probes and adding bounded VM-service request timeouts during final capture.

0.2.1

• Added bare Dart file launch support by expanding file paths to dart run <file>.
• Improved short-lived Dart process profiling by holding isolates at exit long enough to capture final whole-session CPU and memory snapshots.

0.2.0

• Added memory class artifact inspection helpers for stored session, region, and raw memory profile artifacts.
• Added memory class comparison filters for minimum live bytes and class count limits.
• Added optional DTD disabling for attach sessions when region markers are not needed or the tooling daemon cannot start.
• Normalized artifact output directories to fully resolved paths and kept relative paths anchored against the profiled working directory.
• Allowed artifact readers to summarize per-profile artifact directories such as overall/ and regions/<id>/ in addition to summary.json files.
• Improved package detection for local checkout file://.../<package>/lib/... CPU frames so package filters work outside .pub-cache.

0.1.0

• Initial release of the pure-Dart profiler backend.
• Added launch and attach flows for Dart and Flutter VM-service targets.
• Added CPU summaries, call trees, method tables, memory summaries, and artifact readers.
• Added hotspot, comparison, method inspection, and trend analysis helpers.
