Overview

A full-featured Flutter mobile application that allows users to capture, save, and manage their favorite locations with photos and geolocation data. This project demonstrates enterprise-level mobile development practices with Firebase backend integration and native device features.

Features

Core Functionality

• Photo Capture & Management: Take photos directly from the device camera or select from gallery with automatic quality optimization and cloud storage
• Geolocation Services: Capture precise location coordinates with automatic address resolution using Google Maps Geocoding API
• Interactive Maps: Display saved locations on static map previews with Google Maps integration
• User Authentication: Secure email/password authentication with email verification flow
• Real-time Data Sync: Instant synchronization of places across devices using Firebase Firestore
• Dismissible List Items: Swipe-to-delete functionality with undo capability

User Experience

• Responsive Form Validation: Real-time input validation with helpful error messages
• Loading States: Visual feedback during asynchronous operations (uploads, authentication, data fetching)
• Error Handling: Graceful error handling with user-friendly snackbar notifications
• Smooth Navigation: Intuitive page routing between screens with proper state management
• Modal Interfaces: Bottom sheet for image source selection (camera vs. gallery)
• Custom Theming: Consistent Material Design 3 theme with dark mode support

Technical Skills Demonstrated

Flutter & Dart

• State Management: StatefulWidget lifecycle management with proper controller patterns
• Custom Controllers: Reusable controller pattern for form components (UserImagePicker, LocationInput)
• Async/Await: Proper asynchronous programming with Future handling and error management
• Stream Builders: Real-time UI updates using Firestore snapshots
• Form Validation: Complex form validation with custom validators
• Platform Detection: Cross-platform code with web/mobile conditional rendering

Firebase Integration

• Firebase Authentication: User registration, login, email verification, and session management
• Cloud Firestore: NoSQL database with nested collections for user-specific data
• Firebase Storage: Image upload with metadata, organized folder structure, and download URL generation
• Firebase Functions: Backend cleanup of orphaned images (implemented separately)
• Security: Proper user-based data isolation and authentication state management

Native Device Features

• Camera Access: Integration with device camera using image_picker plugin
• Photo Gallery: Access to device photo library
• Location Services: GPS location retrieval with permission handling
• Permission Management: Runtime permission requests for camera and location

API Integration

• Google Maps Geocoding API: Reverse geocoding to convert coordinates to human-readable addresses
• Google Maps Static API: Generate static map images for location previews
• RESTful HTTP Requests: Proper API calls with error handling using the http package

Architecture & Best Practices

• Separation of Concerns: Clear separation between models, screens, and widgets
• Error Handling: Comprehensive try-catch blocks with timeout handling
• Loading States: Proper UI feedback during async operations
• Memory Management: Proper disposal of controllers and resources
• Code Organization: Well-structured file hierarchy and naming conventions
• Logging: Strategic use of developer logs for debugging

UI/UX Design

• Material Design 3: Modern UI following Material Design guidelines
• Responsive Layouts: Adaptive layouts using SingleChildScrollView and flexible containers
• Custom Theming: Centralized theme configuration with ColorScheme
• Visual Feedback: Loading indicators, fade-in images, and smooth transitions
• Accessibility: Proper semantic structure and color contrast

Overview

This is a cross-platform message board app, in which users can log in and post messages to a global board. All messages are deleted every 24 hours and midnight UTC starts a fresh board. Users must verify their email prior to being allowed to post.

This project builds on to previous foundational mobile app concepts, including page navigation and state management, and adds a backend database using Firebase’s FireStore, Storage, Authentication, Messaging, and Functions services.

Skills

• FireStore to manage chats and user details
• Firebase Authentication to create new accounts, verify email addresses, and log users in to access restricted app features
• Firebase Messaging to manage push notifications
• Firebase Storage to store user-uploaded profile pictures
• Server-side Functions to manage chat and user cleanup, and to push notifications when new chat messages are posted.
