Flutter app development

We need 2 flutter sourcecodes combined into one app: sign up, log in with firebase email/password, sign up, plus forgot password and log out setup. This is a 3 screen app. sign up, login and 1 additional screen with friends. Sign up should have email field, password field, confirm password field. Users screen Neds to have features added so users can share, delete or edit info for each friend on list. They can even share or delete or or a batch of friends, by selecting with a checkbox.
