I need a flutter developer with rich experience in flutter Web!

hey, the web application has a few minor problems. They are not serious problems, but if you could solve the problems for us, we would love to hire you. The state management is done with stacked and provider package. 1.) The navigation in the web application is currently a bit stupid. If the user clicks on the "back" button of the browser, the page is simply reloaded. I would like the previous page to load. So in the end I just want to restore the normal function of the back button. 2.) If the homescreen is reloaded, there are problems loading the data from the database. Only the homescreen has this problem. The web application just fails to load the data. 3.) The first page of the web application transfers the user's contact data to a database. We have to do that because a law requires it during the Corona crisis. I would like to save in the cookies when a user has sent their contact details. So that he doesn't have to enter the data again when he opens the web application a second time. 4.) We currently have no indicator in the menu that shows which page the user is on. Can you implement this function. 5.) I would like to have buttons on the default screen to redirect to certain defined pages. It is stupid for the user if he has to close the tab every time he lands on a default screen. At the moment the user always has to reopen the web application whenever he lands on a default screen. That is very ugly. these are just very small changes, but I have other problems to deal with at the moment. to speed up the process a bit, i would like to get help from you, is that possible?
