@parthshindee @klortiz13 Thank you for the great work guys. However, I'm seeing some inconsistencies with the way that functional methods are being used on data. Before we approve this PR, let's all meet to go over this. This is a good case study for the code style guide project. |

Functions that use BuildContext do not need to pass it as a parameter. Use the context instance variable from the class itself.

I can't tell if this is proper usage of functional-style iterator methods. Let's try to rework this one.

@parthshindee let's meet on this one individually to see the best solution. Possible precedent case for the official Campus Mobile Style Guide

Re-evaluate if this and others like it can be made into const variables.
| titleText: CardTitleConstants.titleMap[cardId], | ||
| errorText: Provider.of<EmployeeIdDataProvider>(context).error, | ||
| child: () => isValidId | ||

Consider putting this into a static private method unless it is only used in this function just once.

This can be converted into functional-style methods.

Summary
This PR addresses performance issues related to lazy loading, stateless widgets, and uncached images (Issue #2068, #2069, #2070).
Changelog
[General] [Change] - Stateful Widget to Stateless where possible
[General] [Add] - Lazy loading to all list like components
[General] [Add] - Caching images
Test Plan
There should be no functional changes in the mobile app. Everything should remain the same. This PR is only intended to improve performance significantly.
