Feature Flag Initializer
Component Detail
Description
Bootstrap service that pre-loads feature flags for the authenticated organization during app startup and after organization selection. Ensures flags are available before any screen renders, preventing partial UI states in BLoC/Cubit state machines that depend on flags at initialization.

Summaries
The Feature Flag Initializer protects users from seeing broken or partially-loaded screens by ensuring all feature controls are ready before the application presents any content. This directly reduces support tickets caused by inconsistent UI states and allows the business to safely roll out new capabilities to specific organizations without disrupting others. It provides the infrastructure for controlled, low-risk feature releases — meaning the product team can test with a subset of organizations before full deployment, reducing costly rollbacks and protecting the brand reputation that depends on a reliable, professional experience.
This is a low-complexity bootstrap component with a narrow but critical responsibility: it must complete before any screen in the app renders. The key scheduling consideration is that it sits at the very start of the post-login flow, meaning any delay or failure here blocks the entire user journey. Dependencies on the feature-flag-repository and feature-flag-cache must be completed and tested first. The graceful fallback to default flags (all disabled) simplifies QA — testers can simulate failure scenarios reliably.
Estimated development effort is low, but integration testing with the organization selection flow requires coordination with the auth and navigation teams.
The Feature Flag Initializer is a mobile-layer service that hooks into the post-authentication lifecycle, specifically after organization selection resolves. It calls `initialize(String organizationId)` which triggers a fetch via feature-flag-repository and warms the feature-flag-cache before the navigation shell mounts. The `reset()` method supports logout/org-switch flows. The `getDefaultFlags()` fallback returns a Map
Care must be taken to await initialization in the app router before pushing any routes.
Responsibilities
- Trigger flag loading immediately after organization selection completes
- Warm the cache before the main navigation shell renders
- Handle initialization errors gracefully by falling back to defaults (all flags disabled)
Interfaces
initialize(String organizationId) → Future<void>
reset()
