Provide a way to programmatically save memory heap snapshot in csv or other human readable format #247

Open KimFromMarietta opened 1 week ago

KimFromMarietta commented 1 week ago

I've been able to save heap snapshots from a running Flutter application to CSV within the devtools. I can also save a memory heap snapshot programmatically from my Flutter application with NativeRuntime.writeHeapSnapshotToFile.

How do I convert the saved heap snapshot to csv or other human readable form? I'd like to parse the saved snapshot instead of viewing it in the devtools UI. Thanks

Run DevTools not connected to the app (for example with VSCode > Flutter Side Panel > Icon "Open DevTools") Open DevTools > Memory Click arrow up button to import the snapshot Save the snapshot as CSV.

Let me know if there are issues.
