I want to launch a small Android-only Flutter app that lets users earn in-app coins whenever they finish a Google AdMob rewarded video. The whole experience must feel effortless for the user, so every screen and flow should prioritise ease of use. Core requirements • Firebase Authentication with Google Sign-In (no email/password screens). • Firestore as the single source of truth for each user’s coin balance—no hard-coded values in the codebase. • Firebase Remote Config so I can raise or lower the reward amount or daily cap without shipping a new version. • AdMob rewarded ads only, full-screen and non-skippable; coins are granted strictly after onRewarded event fires. • Daily impression limit and cooldown logic to curb abuse. • Simple, clean screens: Login, Home (watch ad), Wallet/Profile (show balance). Compliance Everything must follow the latest Google AdMob and Play Store policies. No policy-violating ad placements, no incentivised clicks outside rewarded videos. Deliverables 1. Complete, well-organised Flutter source code. 2. Working Firebase, Remote Config and AdMob integration (I will swap in my IDs). 3. A concise setup guide covering required Firebase console settings, AdMob ad unit creation and any SHA-1/keystore steps. Acceptance check I’ll consider the project done once a test build: • Signs in with Google, • Plays a rewarded ad to completion, • Increments Firestore coins exactly once, and • Reflects any Remote Config change without reinstalling. Timeline I would like the first working build, codebase and guide delivered within a month.

Hi, This is a perfect match for my Flutter + Firebase experience. I’ve built multiple apps involving AdMob rewarded ads, Firebase Auth, and Firestore with secure, abuse-resistant logic. For your app, I will: • Implement Google Sign-In (Firebase Auth) with a frictionless flow • Use Firestore as the single source of truth for coin balance (no client-side hacks) • Integrate AdMob rewarded ads correctly—reward only on onUserEarnedReward • Add Remote Config to control reward amount & daily limits dynamically • Build anti-abuse logic (cooldown + daily cap enforced via backend-safe checks) • Deliver clean, minimal UI (Login, Home, Wallet) with smooth UX • Ensure full compliance with AdMob & Play Store policies You’ll receive a well-structured, scalable codebase, working integrations, and a clear setup guide (Firebase, SHA-1, AdMob IDs, etc.). I can deliver a working build within your 1-month timeline—ready for testing and publishing. Let’s get started. Thanks, Kishan Virani
