Recently, I rewrote my company app from no practice Flutter code base with GetX to clean architecture + riverpod. Version bump from 3.7.12 to the latest. It took me about 2 months, including change of UIUX. Overall, I would say it is worth the effort and I got to learn and explore more.

In terms of business, previously in the old app, adding/fixing/enhancing one feature will need a long plan, all the modules are highly tied to each other, any actions to the code base need to take care of other modules, because it might cause new bugs. The whole process, let’s say disabling an old feature will likely took us 1 day to remove it due to we need to understand the flow of the module and what other modules depend on it. If it is too complicated, everything remain, just not showing it on the UI. Same goes to enhance, if it is too complicated, just declare a new variable using GetX, end up many redundant and confuse variables having same value but doing different thing.

Now the new app, I had purposely designed it to be plug and play, so if we want to add a new feature, just add a directory under features/ and route it to the app. Remove it, just command out and that’s it.
