Add exactly the surface area you need.
Most apps want one dependency. radarscope pulls in all three domains behind a single init call; the rest are here for anyone assembling a narrower dependency graph.
| Package | Role |
|---|---|
| radarscope | All-in-one umbrella — one dependency, one import (Radar.init(...)) for Memory + Performance + Stability, the overlay badge, and the unified Inspector. |
| flutter_leak_radar | Memory runtime — heap sampling, precise object tracking, retaining paths, the Leaks inspector. |
| flutter_perf_radar | Performance + Stability runtime — tracing, frame/jank timing, rebuild counts, startup, error/stall capture. |
| flutter_leak_radar_lint | Static analysis — custom_lint rules that catch undisposed controllers, uncancelled subscriptions, and similar patterns at edit time. |
| radar_trace | Pure-Dart tracer core — spans, latency histograms, per-key stats (count / avg / p95 / total / inter-call interval). |
| leak_graph | Pure-Dart heap-snapshot analysis — object graph, retaining paths, snapshot diffing (no live VM required). |
| radar_ui | Shared design system — tokens, typography, and the dense dashboard widgets. |
Internal packages & apps · not published
What the published packages are built on.
Not on pub.dev — the shared analysis engine, host-side tooling, and the two apps (the DevTools extension and Radar Desktop) that consume it. All open source, all in this repo.
DevTools extension — host-side heap capture list (diff any two), class histogram, retaining paths grouped by closest root, composable filters.
Shared portable analysis engine — snapshot models, memory/performance/stability views, and the controllers/interfaces both the DevTools extension and Radar Desktop build on.
Pure-Dart native-heap model and analysis — a peer to leak_graph for the native (heapprofd/Perfetto) memory lane.
Host-side tooling — Perfetto trace_processor parsing, adb/heapprofd capture control, and the native symbolization producer + symbolize CLI.
Radar Desktop — the standalone macOS-first desktop analyzer app. See the full page →
