Screenshots

App Flow

SplashScreen

App opens with splash screen fragment and navigate to the map screen after showing the ekar logo to the user for 2 seconds.

MapScreen

Map Screen is the main part of the app. In first launch, random markers are placed on the map around Dubai zone. Features is listed below:

• Different colored markers placed in map.
• Click marker to navigate vehicle screen.

VehicleScreen

This screen responsible for showing all details of vehicle such as price, standard seating, booking fee and the other things.

Architecture

This app adopts Clean Architecture behaviour. Here is the package structure:

Core

It is the package that contains all the common and base classes used within the application. Extensions, deciders, utils and base classes are included in this package.

Data

Data package should include response models, data source and api methods. It shouldn't know any logic.

UI

Ui like a feature. It contains Fragments, view models and feature related classes like a domains, mappers and ui models. Make sure that all classes here are specific to the this feature. If it is a class that is also used in other features, it should be moved to the common package.

Di

This package may actually be inside the common module. But I prefer to carry outside of core package to be more visible.

Ui-Component

In large projects, we need to use a view component in more than one place. So i moved common view components under ui-component package.

Tech Stack

• Kotlin , Coroutines , Flow
• Dagger-Hilt - Dependency Injection

TODOs and Improvements

• UI test.
• Better Design
• Unit tests for different screnios
