It's an easy project. I don't know why you are offering so much. If I got that right, this project could be completed within two days. I can do it for you at a much lesser cost. You can pay me as much as you want. I am just looking for a good review.
I am just a student doing my undergraduate degree. I started learning flutter a few months back. I created a lot of apps with flutter charts to train myself in this field. So, I am pretty sure I can do your work. New in freelancer, need money to enjoy my college life. Give me a chance and I will not disappoint you.
