Agile Software Design

Design Descison / Process

1 - Decided to develop in cross-platform using flutter because of the native enviornment provided by flutter. Planned to implement an application with simple interface for user to use. For example, Botometer requires users to manually input Twitter username 1 by 1. We can simplify by reading Twitter API to get our following ids and loop entrys into botometer API and print results. Designed UI with a similar color scheme to twitter, blue / dark blue / grey is the main color scheme here.

2 - Setup Firebase with Twitter Signin Authentication only, thus getting user's twitter uid and username after loggin in the application. Setup Cloud Firestore and create collection with the name of Firebase.instance.currentUser.uid so every user will have their unique database and reused when next login. Set up Twitter Developer Account get API keys, Bearer Tokens, Client id, Client secret to have access to Twitter API. Setup BotoMeter-API via RAPID API. Downgraded our dart package of twitter API to v1.1 after realising Botometer API does not support the new released Twitter API v2.

3 - Map data from APIs into classes, lists, variables and saved the 2 most important variables: Twitter username (screenName) and Twitter uid (id_str) into Cloud Firestore for each user from GET followers/ids. Map GET statuses/user_timeline + GET statuses/user_mentions into required body for Botometer API and connect to Rapid API via HTTP POST method. Map the response.json and get the bot_Score we want. Load the botScore with the important variables into database. The app is constantly reading from the user's database and generate tabs with their info and bot Score for every following account.
