flutter-scene-example build fails

[r2d2Proton]

Thank you in advance for any help you may give. I have been following these steps (https://github.com/bdero/flutter-scene-example) and the build fails. And I am trying to use flutter_scene with impeller in my own project and getting an error below. And the shader that is being complained about (I do not think is in my assets, or source files). Built the Flutter engine using VS2022 on Windows. How do I tie my Flutter app Visual Studio solution file to my local engine build?

Mismatch in shader level

Vertex Shader:
#version 100

Fragment Shader:
#version 300 es

And I searched through a good junk of my C: for those expressions but no luck.

[r2d2Proton]

Stand corrected. flutter/engine/src has 1,311 occurrences. Also a lot in WinSxS javascript files.

[r2d2Proton]

Debugging now. . . a lot to be happy about. Windows should have MSAA available. Has had it for a long time.

[r2d2Proton]

I have been trying to get the sample working but no luck. The sample app does not work. And the same large numbers are persistent regardless of which endian is used. And other people have been reporting issues with other models. Talking to AI, The actual implementations are in the C++ codebase for the Dart VM.

Here is where it goes bad.
During the read function.
The arguments received are correct and valid

@override T read(BufferContext bc, int offset) {
    final objectOffset = bc.derefObject(offset);
    return createObject(bc, objectOffset);
}

It is the return value from the line below that causes the problem (offset = 0):

@pragma('vm:prefer-inline') int derefObject(int offset) => offset + _getUint32(offset);

@pragma('vm:prefer-inline') int _getUint32(int offset) => _buffer.getUint32(offset, Endian.little);

final objectOffset = bc.derefObject(offset);
And objectOffset = 1,179,937,895
