Project Description
- WikiSearch is a Flutter search engine which was build using BLoC/Cubit pattern and powered by the MediaWiki API.
- It also uses the NewsApi to show the latest news in its homescreen.
- WikiSearch also uses caching to improve UX, for caching we have used a NoSQL database called HiveDB.
Working
App Architecture
Application logic flow :
- When initiated either by a function call or initState, cubit receives this request.
- Then the cubit calls the repositories which further makes an API call to fetch this data.
- This data is stored in the cubit and once successful the cubit emits a suitable state and UI changes accordingly.
- If the data was fetched successfully it is cached using HiveDB.
- The UI is displayed according to these states.
BLoC/Cubit Pattern
BLoC is a state management solution for flutter. In this project we have used cubit pattern.
Below is a diagramatic representation of how cubit pattern works :

Caching using HiveDB
Caching is used to improve the app’s performance in terms of UX, caching in this app was implemented using HiveDB.
Hive – Hive is a lightweight and blazing fast key-value database written in pure Dart.
Hive is a NoSQL database which has really great performance in terms of both write and read operations.
Data we are caching in this application:
- Search history (whatever keywords the user searched for).
- List of wiki articles that are being fetched from the MediaWiki API.
