Load glb file from device internal storage in AOS & iOS

If you store 3d models in file system, use getApplicationDocumentsDirectory() this method.
I tried to use getApplicationSupportDirectory(), but it doesn't work on iOS(In Android, it works). I think the viewer cannot find the file in iOS. If you use getApplicationDocumentsDirectory(), the viewer can access the file!

And the viewer's src must be configured as follows.

        width: MediaQuery.of(context).size.width,
        height: MediaQuery.of(context).size.height,
        child: Flutter3DViewer(
          progressBarColor: Palette.valueSky,
          controller: controller,
          src: file://$filePath,
        )
      )

I confirmed that it works well on Android and iOS.
