Unsplash Sample Flutter Project

Welcome to the Unsplash Sample Flutter Project! This repository showcases the implementation of Flutter concepts such as Bloc pattern, Dependency Injection (DI), Code Coverage, Testing, Clean Architecture, Analytics using Mixpanel, Feature flagging & A/B testing using Unleash. Whether you're a Flutter enthusiast or a developer aiming to learn these practices, this project offers valuable insights.

Features

• Implementation of the Bloc pattern for efficient state management.
• Utilization of GetIt for managing and injecting dependencies.
• Codecov setup to ensure thorough testing and quality assurance.
• Well-organized project structure following Clean Architecture principles.
• Utilization of Unleash to demonstrate feature flagging.
• Utilization of Unleash and Mixpanel to demonstrate A/B testing.
• Integration of MixPanel to track user behavior and analyze app usage patterns for better insights.

Getting Started

Follow these steps to set up and run the project on your local machine.

Prerequisites

• Ensure that you have Flutter installed on your machine.
• Git
• Docker
• Ensure that you have Unplash API key
• Ensure that you have Mixpanel API key

Installation

1. Clone the repository:

   git clone https://github.com/AyushBherwani1998/unsplash_sample.git

2. Navigate to the project directory:

   cd unsplash_sample

3. Install dependencies:

   flutter pub get

Start Unleash

1. Clone the Unleash repo:

    git clone git@github.com:Unleash/unleash.git
    cd unleash

2. Create and attach container:

   docker compose up -d

The Unleash instance will be up and running on localhost:4242. The default username and password will be admin & unleash4all respectively.

Enviroment

You need to setup envoirment while working on this sample. Create a .env file under lib/core/ with the following content:

 UNSPLASH_API_KEY = hgs9ZVWrHQncX8d9tLmy-zq21412
 UNLEASH_API_KEY = *:development.xxxxyyyyzzz
 MIXPANEL_API_KEY = f9cbf11xxxxxxxxxxxxc695db39a

Project Structure

The project adheres to Clean Architecture principles, promoting separation of concerns and maintainability. Notable directories include:

• lib/features/**: Contains the primary application code.
• lib/features/**/data/: Manages data handling, repositories, and data sources.
• lib/features/**/domain/: Encompasses business logic, use cases, and entities.
• lib/features/**/presentation/: Handles UI components, Blocs, and Widgets.

Dependency Injection

Dependency Injection (DI) is facilitated using the get_it package. This fosters organized code and enhanced testability by efficiently managing dependencies.

Testing

Unit and widget tests are included to ensure code reliability. Execute tests with the following command:

 flutter test

Code Coverage

Code coverage is enforced using test coverage tools like codecov. This helps track tested code areas and identifies segments needing more thorough testing. You can checkout the Grid graph for the repo below:

Analytics

For app analytics we are using Mixpanel. It's used to track the user behavoiour and usage pattern in the application. You can checkout a gist of app analytics in the screenshot given below:

A/B testing

For the app we are using Unleash to perform A/B testing and mixpanel to collect analytics and funnel.

Configuration:

• Create likeOptionExperiment flag in Unleash instance with toggle called experiment
• Create two varinats gridTile and imageDetails for testing
• Enable the flags 🎉

Below is a funnel screenshot for “like image” experimentation
