Flutter App U2Net Model File Issue -- 2

I need help with my Flutter app that's designed to remove image backgrounds using the U2Net model. The app has a crucial function that isn't working because it's not reading the u2net_model.tflite file correctly. The file is located in the assets folder of my project.

I'm specifically looking for someone who can assist me with:
- Correctly setting up the model file
- Diagnosing and fixing a file format error

Ideal candidates would have:
- Extensive experience with Flutter
- Deep understanding of TensorFlow Lite model files
- Proven track record of debugging Flutter applications
- Familiarity with image processing apps
