Minimalist State Management

This repository demonstrates an efficient implementation of state management in Flutter using a service locator pattern with getIt. The primary goal is to achieve reactive code without resorting to imperative approaches like setState. The code is designed to observe changes only in the needed areas, eliminating the need to rebuilding unneccessary areas..

Acknowledgements

Special thanks to Ozkan Kaya for providing the insightful tutorial and code implementation on efficient state management using service locator in Flutter. This project drew inspiration and learning from his work.

How to Use

1. Setup getIt: Initialize the service locator getIt in the main function by calling initGetIt().
2. Widgets:
   • MyHomePage: Represents the main page of the app. It utilizes CounterState and ListViewState for managing state.
   • CounterText: Widget responsible for displaying the current counter value.
   • ListViewContainer: Widget for displaying a list of posts with add and remove functionality.
3. State Management:
   • CounterState: Manages the counter state with methods for incrementing, decrementing, and resetting the counter.
   • ListViewState: Manages the list of posts with methods for adding and removing posts.
   • Both CounterState and ListViewState utilize ValueNotifier to notify listeners of state changes.
4. UI Components:
   • AlertDialog: Displays a warning when the counter reaches 10, prompting the user to continue or reset.
   • AppBar: Customized app bar with an icon.
   • FloatingActionButton: Allows adding new posts to the list.

Key Features

• Reactive Code: Utilizes ValueNotifier and ValueListenableBuilder to achieve reactive behavior without relying on setState.
• Service Locator Pattern: Uses getIt for efficient and centralized dependency management.
• Separation of Concerns: State management logic is separated from UI components for better code organization and maintainability.

Dependencies

• flutter/material.dart: Flutter framework for building UI.
• get_it: Package for implementing the service locator pattern.

Getting Started

1. Clone the repository.
2. Ensure Flutter SDK is installed and up-to-date.
3. Run flutter pub get to install dependencies.
4. Run the app on your preferred device or emulator.
