ProfileArtifactStore class

Writes session and region artifacts for a profiling run.

A store instance owns one session directory. It writes the session summary, whole-session profile artifacts, and per-region summaries under stable file names that ProfileArtifacts can read back later.

Constructors

ProfileArtifactStore(Directory sessionDirectory)

Creates an artifact store rooted at sessionDirectory.

writeOverallFailure({required String isolateId, required List<String> isolateIds, required String error}) → Future<ProfileRegionResult>

Writes a failed overall session summary to disk.
