morphic 0.2.0-dev.3

Multi-window framework for Flutter desktop: build real windows, inspectors, tool palettes, detached panels, workspaces and spatial surfaces from one Dart codebase.

Morphic

A Flutter package that adds a native multi-surface runtime to your Flutter desktop app (Windows).

A normal Flutter desktop app is one window with one widget tree. Morphic lets one app present many sovereign windows — each its own Flutter engine — that the runtime orchestrates (geometry, z-order, activation, lifecycle) while staying agnostic to what any window contains. You author it all in Dart.

⚠️ Morphic is pre-1.0, Windows-only, and currently focused on desktop runtime stabilization.

The install flow and native runtime are operational and scratch-verified, but APIs and runtime behavior may still evolve rapidly.

import 'package:morphic/morphic.dart';

void main() => runMorphicApp(app: MyApp());

class MyApp extends MorphicApp {
  @override
  String get name => 'My App';

  @override
  List<SurfaceSpec> surfaces() => const [
        SurfaceSpec.workspace(id: 'main', entrypoint: 'mainSurface'),
      ];
}

Two runtime modes

Morphic has two genuinely different runtime shapes — not "the same thing with extra effects":

• Native mode — orchestrated multi-window runtime. Sovereign OS windows; closing the last one exits the app. The default, free.
• Spatial mode — a composited spatial runtime: GPU-composited, shaped, materialized surfaces inside a persistent shell. Premium.

See doc/RUNTIME_MODES.md.

Install & first run

flutter create my_app && cd my_app
flutter pub add morphic
dart run morphic:init        # transforms windows/runner to host the runtime (reversible)
# point main() at runMorphicApp(...), then:
flutter run -d windows

dart run morphic:init patches your Windows runner to hand process bootstrap to the Morphic runtime and materializes the runtime sources into windows/runner/. It leaves lib/, your pubspec config, and every non-Windows platform untouched, and is fully reversible (dart run morphic:remove). No C++, no CMake, no Win32.

Status & engineering signals

Pre-1.0 and evolving, but the runtime core is stabilized and the consumption path is real:

• The install path is scratch-verified (init → build → run → remove, on a clean flutter create app).
• A runtime invariant assertion layer, an explicit lifecycle/teardown state machine, and an engine-retention model are all in place and behaviorally verified.
• Native and spatial are separate, verified runtime tiers (the native tier compiles and runs with zero spatial dependencies).

example/ is a showcase / playground / reference app, not the place you author your own app — that's package:morphic in your own project.

The pre-pivot Dart API (MorphicController / createSurface / "Studio") is a dead lineage, quarantined under legacy/. Ignore it.
