I'm seeking a professional experienced in Flutter Android development and Firebase App Check to create a Flutter Android app integrated with Firebase with App Check security enforced. Specifically, the app should utilize AppCheck authentication through a custom provider. The project's primary features include: - Development of a Flutter Android app - Integration with Cloud Firestore - Implementation of Firebase authentication via App Check (custom provider) Since our Android apps are not distributed via the Play Store, we are unable to utilize the default Play Integrity provider. Consequently, we cannot use the sample Flutter implementation provided by Firebase (refer to: [login to view URL]). The project aims to deliver a sample Flutter Android app. Here, the client will request an access token (the API to obtain a valid token will be provided) and submit a query to Firebase Cloud Firestore along with this token to gain access to Firebase Firestore collection. The project milestones are as follows: 1) Creation of a Firebase sample project with a Firestore collection and sample data 2) Development of a Flutter Android app capable of reading data from Firestore 3) Installation and enforcement of App Check security (to block all unauthenticated access to Firestore) 4) Modification of the Flutter app to include a valid App Check token with every request, thereby regaining access to Firestore data. Ideal skills for this project include: - Proficiency in Flutter Android development - In-depth understanding of Firebase App Check
