Random Cat Generator Using Clean Architecture #

Objective #

This very basic Dart/Flutter project demonstrates the use of clean architecture to build a full stack application.

Users can use this application as a reference to strengthen their skills around designing apps with a clean architecture and wirting code using the SOLID design principles.

The code is mainly Dart (core business logic) with bits of Flutter (which you can swap with a UI library of your choice).

Structure #

• One screen.
• One button.
• One placeholder for cat images.

Workflow #

• App launches.
• User presses the button.
• A call is made to the random cats API.
• A loading indicator is shown while the call is performed.
• A cat picture is displayed in the screen when the response is successful.
• If no connection we show an error message.
