A Flutter project to showcase simple API REST calls and info display.

PokeReader

Installation

• Make sure you have Flutter v1.20.4 installed
• Run flutter packages get in the project folder
• Run flutter run --release in the terminal

If the project doesn't run, verify the errors that the console is throwing and contact ElZombieIsra

Technical showcase

The technical skill to evaluate in this assestment are:

• Data persistency
• Http calls to an API
• Folder structuration
• Technical concepts differentiation
• Asynchronus programming
• CLEAN architecture use
• Hero animations
• State management with BLoC

Packages chosen

Here lies a list of all the packages chosen to make the assestment an a small explanation why they were chosen

• flutter_bloc: ^6.0.5: A state manager for API calls and reactive programming. Chosen because I feel comfortable structuring apps with this package, its the one recommended by Google and with the latest major update that introduces Cubit it's more easy to build apps with it.
• equatable: ^1.2.5: This plugin was used to have better equality comparisons within Dart and the built models.
• json_serializable: ^3.4.1: Chosen for code generation of the toJson and fromJson methods used in the built models. It helps to build models and consume APIs faster.
• tuple: ^1.0.3: Used because I needed to return multiple values from a method but without building a custom Model. This package allows to return a Tuple with multiple strongly typed values so the developer always knows what to expect. Thats an advantage over using Map<String, dynamic> or a List<dynamic> to return the values.
• dio: ^3.0.10: Http calls improved for status code checks, transformers, improved errors, etc.
• shared_preferences: ^0.5.10: Chosen over other data persistency options because it's simple to use and for this use case we didn't need something more robust.

Areas to improve

• Some models were not parsed for simplicity of the code but they can be generated.
• The data persistency needs to be migrated to something more robust if the project scales up.
• Some methods can be commented so the developers have a little more context about what a method do.
• Implement dependency injection.
