A Clean Google Map Component Implementing MVVM Build with Flutter SDK ( SOLID Principles & Unit-Testing Applied )
Code Files separated by Package-by-feature Concept
Each layer in MVVM separeated from upper layer , dont know about its Upper Layer ( View -> VM -> Repo ) VM dont care about View dont have View Reference , Just subscribing with VM's Rx Subject which callback with any updates
Code is made Testable with dependency injection concept , you can test Repo separately & test VM separately without View
Unit Testing is applied in spearte file for testing util functions's logic
Logger abstract class is added for tracking process for each logic class
The project contains a little bit of Over Engineering but it's just a side-project not for commercial use
Some of SOLID Principles applied :
D Dependency Inversion Principle as every Function depends on Abstraction & injected by dependent paramter instead of closing it in the scope , it makes the code testable for unit-testing assertion and helps in loosing the tightly coupling
I Interface Segregation Principle as each layer has its own interface that contain only primary functions for Implementer classes , so there on unneeded Override for child classes
S Single-Responsibility Principle as each Function for only one job
Unit Testing is Added :
- It tests util funcitons's logic
- A Group of testing cases for repaintMarkerIcon() Method is added
- Code Coverage isn't high enough , but it covers the important Methods
