Banned Terms

Avoiding ambiguous names in software is as important as choosing meaningful names. The following is a list of names to avoid in your code.

Controller

The term "controller" has a very specific meaning in Flutter development. A Controller is an object that shares data and control both inside and outside a widget. For example, Flutter defines ScrollController, AnimationController, and TabBarController. Unless you're defining an object with a similar purpose, you should avoid the term "controller" so that the term doesn't become overloaded.

Helper

Every piece of code that you write "helps" you to do something. If it didn't, you wouldn't write it. Calling something a "helper" communicates nothing.

Utility

Every piece of code that you write is a "utility". Calling something a "utility" communicates nothing.

Manager

All code "manages" things. In general, calling something a "manager" adds no new information. The only exception to this rule is when the term "manager" is used to describe an object that owns full authority over some resource. For example, "Bluetooth Manager", "File System Manager", "Memory Manager".

Data

Sometimes a class exists to hold structured data, i.e., a "data structure". While it's tempting to call that class "data", the word "data" adds nothing. Rather than define UserData, StockHistoryData, PostData, you should call these things User, StockHistory, and Post, which communicates the same information with less verbosity.

Model

Everything in code is a model. Rarely is it useful to add the word "model" to some other term. "View Model" is the rare exception to this rule. Otherwise, things like UserModel, StockHistoryModel, and PostModel could simply be called User, StockHistory, and Post.
