leak_graph 0.1.0

Pure-Dart library for loading VM heap snapshots and analysing object retaining paths to surface memory leaks.

0.1.0

Initial release.

Pure-Dart heap-snapshot analysis: load a VM heap snapshot, build an object graph, and find the retaining paths that keep suspected leaks alive — with no dependency on a live VM-service connection.

• heapGraphFromBytes / loadHeapGraph — parse a .data heap snapshot (e.g. from NativeRuntime.writeHeapSnapshotToFile) into a HeapGraphView. Never throws on malformed input; returns a sentinel graph instead.
• GraphLeakAnalyzer.analyze — the end-to-end pipeline: BFS shortest retaining paths, leak-prone root classification (timer / stream / closure / finalizer / static), app-relevance filtering, optional live-tree confirmation, and clustering by retaining-path signature. Each leak is attributed to the deepest app-owned object on its path, with the SDK chain kept as detail.
• retainingPathForClass(graph, className) — shortest retaining path to the first reachable instance of a class (standalone, no VM service).
• HeapGraphView.classHistogram() — per-class instance counts derived from the snapshot, for VM-service-free heap-growth detection.
• bin/analyze.dart — CLI that analyses a heap-snapshot file and renders a report.
