State Management

Overview

Three contexts are used to manage commonly used states within the mobile app.

1. Localization: global modules to translate messages and labels using expo-localization.
2. Auth Context: global variable to toggle between login screen and survey features.
3. Survey Editor Context: global variables to manage editing survey values. The Survey Editor screen consists of several types of child components that depend on the field type. The parent screen itself centralizes this context, and when a field worker updates an item value on the screen, the field value is propagated from the child components to the parent screen.

See src/context folder for the full source code.
