[Feature Request] Support runtime GLB import (or provide a documented/runtime-safe importer API)

[Epersonf]

Hi! First, thanks for the amazing work on flutter_scene.
I'm currently building a map editor application (desktop) where users import 3D models dynamically at runtime. Ideally, users should be able to select a .glb file and see it immediately in the 3D viewport.

I’ve learned that flutter_scene currently works like this:

.glb → .model conversion is handled by the native importer tool

Flutter can only load .model files via flatbuffers at runtime

The GLB importer logic is not exposed as a runtime API

This means runtime GLB import is not currently possible inside a Flutter app without shipping and managing external platform-specific binaries.

❗ Issue

The helper utilities in flutter_scene_importer (such as importGltf) rely on:

Isolate.resolvePackageUriSync

build-time directory layout (e.g. /build/_deps/...)

Flutter/Dart toolchain being installed

So they cannot safely be called in a production runtime environment, because:

The build/ directory isn't included in release builds

Package URIs may not resolve in release/AOT

Toolchain dependencies won't exist on user machines

This makes it difficult to build applications that allow dynamic model import, which is a common requirement for editors and content-creation tools.

💡 Feature request

It would be extremely useful to have one of the following:

Official runtime-safe GLB import support
(even if desktop-only at first)

or

A documented/runtime-safe API for accessing the importer, such as:

a stable executable distributed with the package

or an embeddable Dart API

or a recommended integration pattern

👍 Why this matters

Enables real-world 3D tooling (editors, content apps, etc.)

Matches what engines like Unity/Godot provide

Keeps .glb as a universal format while using .model internally

🙏 Thanks

Totally understand this is early-preview software and priorities are evolving, this is just feedback from someone trying to use Scene in a production-style workflow.

If runtime import is explicitly out-of-scope right now, clarification in docs would also help a lot.

Thanks again for the awesome work!
