TFLite Conversion Issues and why my tflite model looks like this?

on the right is before conversion and on the left is after

these are my conversion parameters

converter.target_spec.supported_ops = [
    tf.lite.OpsSet.TFLITE_BUILTINS,  
    tf.lite.OpsSet.SELECT_TF_OPS  
]

this is the error I got in flutter
apperently the FULLY_CONNECTED op is not supported in tflite.
how do i fix it ?
I tried other tflite_flutter versions but no luck

pretty sure something wrong with my base model

I’m new to this

Didn’t find op for builtin opcode ‘FULLY_CONNECTED’ version ‘12’. An older version of this builtin might be supported. Are you using an old TFLite binary with a newer model?
