Flutter Model Viewer 不显示任何内容

问：

我正在尝试使用 flutter 的模型查看器加 （https://pub.dev/packages/model_viewer_plus） 并且我已经集成了它，但 ModelViewer 没有显示在我的应用程序中。屏幕工作正常，但根本不显示模型。我试图将模型直接放在屏幕文件甚至资产文件夹中，但似乎没有任何效果（也尝试了在线模型 url，但仍然不起作用）。

这是我的屏幕文件

import 'package:flutter/material.dart';
import 'package:model_viewer_plus/model_viewer_plus.dart';

class PlaceModel extends StatelessWidget {
  const PlaceModel({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text("Model Viewer")),
        body: ModelViewer(
          backgroundColor: Colors.teal,
          src: "E:\\BuildVisionFYP\\build_vision_fyp\\public\\models\\Duck.glb",
          alt: "A 3D model of an astronaut",
          ar: true,
          autoRotate: true,
          cameraControls: true,
        ),
      ),
    );
  }
}

这是我的pubspec.yaml

我也附上了屏幕的屏幕截图 截图

我也在日志中得到这个：

HTML generated for model_viewer_plus:

<style>
    body,
    model-viewer {
        width: 100%;
        height: 100%;
        margin: 0;
        padding: 0;
    }

    /* other-css */
</style>

<model-viewer src="E:\BuildVisionFYP\build_vision_fyp\public\models\Duck.glb" alt="A 3D model of an astronaut" ar camera-controls auto-rotate style="background-color: rgba(0, 150, 136, 255); ">
</model-viewer>

请帮忙谢谢
