What is magic_devtools?

magic_devtools is the Magic adapter layer for fluttersdk_dusk and fluttersdk_telescope. It enriches dusk snapshots and telescope records with Magic-aware context (forms, navigation, controllers, gates, auth, broadcasting, HTTP) so an LLM agent or CI driver sees your app the way Magic sees it.

It is debug-only: you install and wire it under kDebugMode, so release builds tree-shake it entirely and it carries no runtime cost in production. This is exactly why it lives outside magic core; the framework keeps no dev-tooling production dependencies.

Four import barrels:

• package:magic_devtools/magic_devtools.dart: MagicDevtools is the umbrella one-call wiring: installPre() boots both tool plugins (plus telescope's opt-in exception/dump watchers) before Magic.init(), installPost() wires both Magic integrations after it.
• package:magic_devtools/dusk.dart: MagicDuskIntegration registers 14 Magic-aware enrichers into fluttersdk_dusk's snapshot pipeline.
• package:magic_devtools/telescope.dart: MagicTelescopeIntegration registers 5 Magic watchers and MagicHttpFacadeAdapter into fluttersdk_telescope.
• package:magic_devtools/preview.dart: MagicPreview hosts a dev-only component preview catalog via two plain pages (/preview and /preview/:component), tree-shaken from release builds.

Install

magic_devtools and the tooling packages are imported in lib/main.dart (under kDebugMode), so they are regular dependencies, not dev_dependencies; kDebugMode tree-shakes them out of release builds, and because lib/ imports them a dev_dependencies entry would trip the depend_on_referenced_packages lint. This matches how fluttersdk_dusk and fluttersdk_telescope are installed on their own.

dependencies:
  magic_devtools: ^0.0.2
  fluttersdk_dusk: ^0.0.9        # add if you use dusk
  fluttersdk_telescope: ^0.0.4   # add if you use telescope

magic_devtools depends on magic, fluttersdk_dusk, and fluttersdk_telescope directly, so transitive resolution does not happen through magic itself.

Wiring

Both integrations are debug-only and run in lib/main.dart. The ordering is load-bearing: the dusk/telescope plugin installs before Magic.init() (so the snapshot pipeline is live during Magic boot and the exception watcher catches boot errors), and the Magic integration installs after Magic.init() (its enrichers and adapter resolve Magic primitives through the IoC container).

Both tools at once (recommended)

MagicDevtools collapses the four blocks below into the two halves of that ordering. Keep the kDebugMode guard at the call site: moving it inside the methods would make the call live in release and defeat the tree-shake.

if (kDebugMode) MagicDevtools.installPre();   // dusk + telescope plugins + exception/dump watchers
await Magic.init(configFactories: [...]);
if (kDebugMode) MagicDevtools.installPost();  // MagicTelescopeIntegration + MagicDuskIntegration

Reach for the individual barrels below when you need only one tool, or a non-standard telescope watcher set (register extra watchers with TelescopePlugin.registerWatcher after installPre).

Dusk

if (kDebugMode) {
  DuskPlugin.install();
}
await Magic.init(configFactories: [...]);
if (kDebugMode) {
  MagicDuskIntegration.install();
}

Telescope

if (kDebugMode) {
  TelescopePlugin.install();
}
await Magic.init(configFactories: [...]);
if (kDebugMode) {
  MagicTelescopeIntegration.install();
}

You can wire either integration on its own, or both together: install each plugin before Magic.init() and each Magic integration after it. The dusk:install and telescope:install Artisan commands wire these blocks into lib/main.dart automatically when magic_devtools is a dependency.

Preview catalog

MagicPreview hosts a dev-only component preview catalog: a sidebar of registered components next to each preview rendered in BOTH light and dark, with a global theme toggle bound to wind's WindThemeController. It is reachable only through MagicPreview.registerRoutes(), guarded by kReleaseMode plus const bool.fromEnvironment('PREVIEW_ENABLED', defaultValue: kDebugMode), so the route, the catalog, and every registered PreviewEntry const-fold dead and tree-shake out of release builds.

The router-lock timing is load-bearing: MagicRouter locks its route table on the first routerConfig access, so registration MUST happen in a provider boot() (which runs during the Magic bootstrap lifecycle, before MaterialApp reads routerConfig). Register too late and /preview silently never appears.

class RouteServiceProvider extends ServiceProvider {
  RouteServiceProvider(super.app);

  @override
  Future<void> boot() async {
    registerAppRoutes();
    if (kDebugMode) {
      MagicPreview.register(previewEntries()); // from the generated _previews.g.dart
      MagicPreview.registerRoutes();
    }
  }
}

The previews:refresh Artisan command scans *.preview.dart files and regenerates previewEntries() returning a List<PreviewEntry> from a function (never a top-level const, the dart-lang/sdk#33920 retention foot-gun).

Local development resolves the magic, fluttersdk_dusk, and fluttersdk_telescope siblings through a gitignored pubspec_overrides.yaml (path entries to the sibling clones). Create one alongside pubspec.yaml:

# pubspec_overrides.yaml (gitignored; local path wiring only)
dependency_overrides:
  magic:
    path: ../magic
  fluttersdk_dusk:
    path: ../dusk
  fluttersdk_telescope:
    path: ../telescope
