I’ve been working on a Flutter project and need to display stl, obj, stp, step, igs, iges files. I have tried various available packages such as flutter_3d_controller, model_viewer_plus, three_dart, and many more. All of these packages support either GLB or GLTF file formats, but not the mention file formats.

I also attempted to convert my STL files to GLB using different tools and methods, but was unsuccessful in doing so.

Can anyone guide me on:

1. How to successfully view STL files in Flutter?
2. Reliable tools or methods to convert STL files to GLB (if conversion is the only solution)?

Any help or guidance would be greatly appreciated. Thanks in advance!
