Why Remove Modules?
Modules represents functions or parts of the Firebase SDK. Not the whole SDK is always required. If modules are not removed, the whole Firebase SDK gets loaded. Removing Modules Allows you to select which features you will be using. Accordingly, it will load the Firebase SDK, and load only the features that are needed. Being able to select which features you need will reduce the amount of unnecessary, unused codes loaded. This greatly reduces Memory usage.
