Premium FlutterFlow Football Journal App

am looking for an experienced FlutterFlow developer to build a clean, native mobile app for a parent-managed "Football Performance Journal" connected to a Google Firebase backend. The UI needs a premium dark-themed aesthetic inspired by console video game menus (like EA FC / FIFA Career Mode). TARGET AUDIENCE & APPLE COMPLIANCE: * This app is a parent-managed tracker. The primary account holders are parents logging stats for their children. * PRIVACY MODE: The app must be 100% private per account. No user can see another user’s data. There are zero public social-sharing feeds. * The app must comply fully with Apple App Store Guideline 1.2 (UGC) and COPPA privacy standards. CORE SCREEN REQUIREMENTS (3 SCREENS TOTAL): 1. Screen 1: Player Profile Dashboard (FIFA-Style Career Hub) - Top section: Circular avatar photo (uploaded by parent), child's name, team name, and position. - A 4-column metric grid displaying running season totals: Appearances (APP), Minutes Played (MIN), Goals (GLS), and Assists (AST). - A Read-Only Star Rating bar displaying the calculated average match performance score. - A prominent, styled action button labeled "＋ LOG NEW MATCH" that triggers the input form. 2. Screen 2: Match Log (Chronological History Feed) - A vertical scrolling ListView of all past logged matches (sorted newest to oldest). - Each list item displays: Opponent Name, Date (formatted relative/clean), Final Scoreline, and a color-coded tag for the result (Green for W, Red for L, Grey for D). - Tapping any row passes that specific match parameter and navigates to Screen 3. 3. Screen 3: Digital Scrapbook (Match Detail View) - A high-visual detail canvas for the selected match. - Top banner: Wide-span Hero Image pulling from that match's uploaded photo. - Inline dashboard showing that single match's statistics and a native read-only star bar. - An expandable text container displaying "Manager's Tactical Notes" for long-form journal reflections. - Premium Tier Feature: A native VideoPlayer widget that streams an external match highlight link (YouTube, Veo, or HUDL URL pasted by the parent). BACKEND & CLOUD LOGIC (FIREBASE): - Two Collections: `User/Player Profile` and `Match Log`. - The "Log New Match" Form: Inputs for Opponent, Venue (Home/Away choice chips), Scoreline, Minutes, Goals & Assists (CountControllers/steppers), Match Rating, Long Text Area, Video URL string, and an Image Picker for the photo. - Cloud Aggregations: Configure data streams so that submitting a match automatically triggers backend calculations on Screen 1 (Summing goals, assists, minutes, counting appearances, and averaging ratings). - Authentication: Simple email/password login or Sign-in with Apple. DELIVERABLES: - Fully functional FlutterFlow project link with no compilation errors. - Firebase database completely integrated with structured collections and data privacy security rules configured. - Immersive UI styling following a premium dark-mode sports aesthetic.
