Offline DistilBERT Model Integration in Flutter with .onnx format file

I have the distilberd model in .onnx format. it cant be done with tflite as i have not used tensorflow in my project. i need a flutter developer to start the integration immediately. it is a model for text classification. my budget is no more than 25 euros for each model. i have 3 models in total all similar on the same application. please bid only if you have time and agree with the budget. i dont want any bargain
