Flutter WebView App with Biometric Login

We are looking for an experienced Flutter developer to create a WebView-based mobile app for both Android and iOS. The app will include Firebase for notifications and device authentication and support biometric login. Below are the detailed requirements: App Requirements: Login Screen (First Screen Activity): Design a simple login screen with: Two input fields: Email and Password. Login button: Sends Email, Password, and Firebase device ID token to our server API. Hyperlink buttons: "Create New Account" and "Reset Password" that redirect to specific URLs (provided later). Error Handling: If the login attempt fails (due to incorrect email or password), display an error message. Successful Login: On successful login, retrieve a LOGIN_KEY from the JSON response and redirect the user to a WebView URL: [login to view URL] Firebase Integration: Set up Firebase for app notifications. The app must support background notifications (notifications should appear even when the app is closed). Show a popup alert prompting the user to enable notifications each time they open the app if they have disabled notifications. Biometric Authentication: After the first successful login, store the LOGIN_KEY in the app’s local storage. Add a "Fingerprint" button for subsequent logins, allowing the user to authenticate with their fingerprint and log in automatically with the stored LOGIN_KEY. If the user logs in again with Email and Password, update the stored LOGIN_KEY. Additional Requirements: Use Flutter to ensure the app works seamlessly on both Android and iOS. Code should be clean, well-documented, and follow Flutter development best practices. Ensure smooth UI/UX with Firebase notification integration for a professional app experience. This is a basic outline. If you have questions or need further clarification, please reach out. Looking forward to finding a skilled developer to bring this project to life!
