Help needed in my Project

The above link has all files attached to my project including a demo video…So basically it is a disease predictor based on symptoms given as input. This would be executed on a raspberry pi with 5 inch display…So i have 2 problems in it…I cant change the font size. I searched online and tried and it didnt sort it out yet…Second thing is symptoms and the predicted disease gets stored in the firebase(realtime)…The code for firebase is written but it stores only two initial symptoms…So if anyone could help that would be kind enough…
