Flutter Examples
This project is a collection of reference implementations and sample applications for Flutter. It provides practical examples covering API integration, user authentication, data persistence, and a gallery of UI patterns.
The repository distinguishes itself by offering a wide array of functional demos, including implementations for Google and email-based identity verification, cloud database synchronization, and the use of both relational and key-value local storage. It also includes specialized utility examples such as expense tracking, tip calculation, and body mass index tools.
The project covers a broad surface of development capabilities, including reactive state management, asynchronous networking, and platform-adaptive rendering. It demonstrates a comprehensive set of interface components ranging from data visualization charts and complex date pickers to navigation drawers and infinite scrolling lists.
The codebase includes unit testing for verifying logic in isolation and demonstrates various system integrations such as splash screens and PDF handling.
Features
- Flutter - Offers a wide collection of sample applications demonstrating common layouts, state management, and widget usage in Flutter.
- Local Persistence Implementations - Provides practical demos for persisting data using local key-value stores and relational databases.
- UI Pattern Implementations - Includes a gallery of reference implementations for navigation drawers, tabbed interfaces, and adaptive layouts.
- User Identity Verification - Demonstrates user identity verification using Google sign-in and email-based authentication.
- Composition Hierarchies - Builds user interfaces using an immutable hierarchy of nested widgets that rebuild on state change.
- Reactive State Management - Implements reactive state management to synchronize UI elements with underlying data changes.
- UI Composition - Implements a reactive UI architecture where components rebuild based on mutable state changes.
- Cloud Synchronization Services - Synchronizes application data to a remote cloud database for real-time persistence across devices.
- External State Stores - Coordinates application state using external systems to maintain consistency across the interface.
- Key-Value Persistence Stores - Uses persistent key-value stores to save small pieces of data and settings on the device.
- App Settings Persistence - Saves application settings to disk using key-value stores to maintain state across restarts.
- Local Persistence - Implements local storage mechanisms to persist application data and support offline access.
- Remote Data Fetching - Implements asynchronous HTTP requests to retrieve remote data for populating application content.
- Relational Local Storage - Persists application state on the device using a local relational database.
- Frontend State Tracking - Tracks data flow and reactivity to trigger user interface updates based on changes to internal state.
- Backend-as-a-Service Integrations - Implements integrations with cloud-based backend services for authentication, crash reporting, and analytics.
- Cloud Backend Connectivity - Connects mobile applications to cloud services for identity verification and real-time data sync.
- Navigators - Manages screen transitions using a push-pop stack model for hierarchical navigation.
- Stack-Based Navigation History - Manages screen hierarchies using a push-pop stack to control view transitions and history.
- Asynchronous HTTP Clients - Uses non-blocking HTTP clients to fetch remote data for dynamic lists and statistics.
- Email Authentication Strategies - Implements a sign-in system for users to register and verify identity via email and password.
- Google OAuth Providers - Provides identity verification using Google as a third-party OAuth provider for secure sign-in.
- Bottom Navigation Bars - Includes mobile-friendly navigation bars positioned at the bottom of the screen.
- Application Theme Definitions - Defines unified visual styles through centralized application-wide theme overrides.
- Infinite Scroll Components - Provides components that automatically fetch and append content as the user scrolls to the end of a list.
- Platform-Adaptive Interfaces - Renders user interface components that automatically adapt their appearance based on the host operating system.
- UI Components - Implements a side-menu interface using gestures and animations for application navigation.
- Tabbed Navigation - Implements horizontal tabbed navigation to organize content into separate views.
- Virtualized List Rendering - Implements efficient rendering of large datasets using scrollable, virtualized lists.
- Développement mobile - A repository of Flutter code examples and patterns.
- UI Components - Collection of simple, standalone application examples.
