Flutter Interface phone and tablet

We are making some tests for a development. We want to see it working in phones and tablets using flutter. The application is already developed in ruby-on-rails, the back end is done, the native front end is done and the api for flutter is done. You would have to make the flutter front end. We have attached a document where you can see the details of the interface to be developed. We would like to have from you the time and cost for each screen of the attached document. Not one global price and time but a time and price for each screen in the document. Please read the document carefully, we think you can find all the necessary information for your quote in it. Do not hesitate to ask for any doubt. Thanks in advance
