Flutter Travel App

A modern Flutter travel application built with GetX state management, featuring travel packages, blogs, and a clean architecture pattern.

🌟 Features & Implementation Details

Navigation System

• GetX Navigation: Implemented using Get.toNamed() for route management
• Bottom Navigation: Custom implementation with IndexedStack for state preservation
• Route Management: Centralized in app_pages.dart with named routes

class AppPages {
  static const initial = Routes.main;
  static final routes = [
    GetPage(
      name: Routes.main,
      page: () => const MainNavigationScreen(),
      binding: NavigationBinding(),
    ),
  ];
}

State Management

• GetX Controllers: Reactive state management using .obs variables
• Controller Bindings: Dependency injection through NavigationBinding

class NavigationBinding extends Bindings {
  @override
  void dependencies() {
    Get.put(NavigationController());
    Get.put(HomeController());
    Get.put(ExploreController());
    Get.put(ThemeController());
    Get.put(NotificationsController());
    Get.put(ProfileController());
  }
}

Search & Filtering Implementation

• Base Search Controller: Reusable search functionality

class BaseSearchController extends GetxController {
  final RxString searchQuery = ''.obs;
  final RxBool isSearching = false.obs;

  void onSearchChanged(String query) {
    searchQuery.value = query;
  }

  void toggleSearch() {
    isSearching.value = !isSearching.value;
    if (!isSearching.value) {
      searchQuery.value = '';
    }
  }
}

Travel Packages Feature

• Data Model:

class TravelPackage {
  final String id;
  final String name;
  final String description;
  final double price;
  final String duration;
  final String imageUrl;
  final List<String> highlights;
  final String location;
  final double rating;
}

• Filtering Categories:
  • All
  • Popular
  • Recent
  • Trending

Blog Section Implementation

• Blog Model:

class BlogPost {
  final String id;
  final String title;
  final String excerpt;
  final String content;
  final String author;
  final String imageUrl;
  final String date;
  final List<String> tags;
  final int readTime;
}

• Category Filtering:
  • All
  • Adventure
  • Culture
  • Food
  • Tips

Theme Management

• Dynamic Theme Switching: Implemented using GetX

class ThemeController extends GetxController {
  final RxBool isDarkMode = false.obs;
  
  void toggleTheme() {
    isDarkMode.value = !isDarkMode.value;
    Get.changeThemeMode(isDarkMode.value ? ThemeMode.dark : ThemeMode.light);
  }
}

🛠️ Technical Implementation

GetX Helpers & Extensions

• Reactive State: Using .obs for reactive variables
• GetView: Base class for views with controller access
• GetBuilder: For non-reactive state management
• Bindings: Dependency injection setup

Navigation Patterns

// Named route navigation
Get.toNamed('/explore', arguments: {'category': 'adventure'});

// Back navigation with data
Get.back(result: selectedItem);

// Snackbar display
Get.snackbar('Title', 'Message');

Theme Implementation

class AppTheme {
  static ThemeData get lightTheme {
    return ThemeData(
      primarySwatch: Colors.blue,
      scaffoldBackgroundColor: Colors.white,
      appBarTheme: const AppBarTheme(
        elevation: 0,
        backgroundColor: Colors.white,
        foregroundColor: Colors.black,
      ),
    );
  }

  static ThemeData get darkTheme {
    return ThemeData.dark().copyWith(
      primaryColor: Colors.blue,
      appBarTheme: const AppBarTheme(
        elevation: 0,
      ),
    );
  }
}

Data Management

• JSON data loading from assets
• Model parsing and serialization
• State persistence using GetX

🚀 Getting Started

Prerequisites

• Flutter SDK (^3.5.4)
• GetX (^4.6.6)
• Dart SDK (latest stable)

Installation

1. Clone the repository

git clone https://github.com/Spritan/Flutter_travel_app_dummy.git

2. Install dependencies

flutter pub get

3. Run the app

flutter run

📱 Platform Support

• Android

🔧 Development Guidelines

State Management Rules

1. Use .obs for reactive state
2. Implement controllers for each feature
3. Use GetView for screens with single controller
4. Implement proper dispose methods

Code Organization

1. Feature-based directory structure
2. Separate business logic from UI
3. Reusable widgets in shared directory
4. Constants in dedicated files

Error Handling

try {
  // Operation
} catch (e) {
  Get.snackbar(
    'Error',
    e.toString(),
    snackPosition: SnackPosition.BOTTOM,
  );
}
