Mentor Location Service
Component Detail
Description
Core service responsible for fetching peer mentor locations within a given geographic bounding box and applying filter criteria. Communicates with the mentor location repository using BLoC/Riverpod state management. Only returns locations for mentors who have given explicit consent.

Summaries
The Mentor Location Service is the core business capability that enables coordinators to discover and connect with available peer mentors in real time. By surfacing only consented mentors within a coordinator's visible map area, it reduces the time spent manually searching for support resources and directly improves response times in high-need situations. The built-in consent enforcement protects the organization from privacy liability and builds trust with mentors who control their own visibility. This component is the primary driver of the platform's geographic matching value proposition, differentiating it from generic directory tools by delivering contextual, location-aware results that improve mentorship engagement rates and operational efficiency.
This is a high-complexity service component that sits at the critical path of the map feature delivery. It depends on both the Mentor Location Repository and Location Consent Service being completed and stable before integration testing can begin. The BLoC/Riverpod state management wiring adds significant development effort and requires a developer experienced with reactive Flutter patterns. Plan for a dedicated QA cycle covering filter combinations, empty-state handling, and consent edge cases.
Any delay in the repository or consent service will directly block this component. Allocate buffer time for integration testing across simulated geographic datasets and ensure the team has capacity to handle async stream debugging during the testing phase.
Mentor Location Service operates as the orchestration layer between the UI state and the data access tier in the mobile execution context. It consumes getMentorsInBounds and getAllFilteredMentors from the Mentor Location Repository, delegates consent validation to Location Consent Service before any data is emitted, and exposes a reactive stream consumed by the map view screen via BLoC/Riverpod. Implement the consent gate as an async precondition inside getMentorsInBounds rather than a UI-layer check to prevent bypass. The refreshLocations() method should debounce map viewport change events to avoid flooding the repository with overlapping queries.
Dispose pattern must cancel all active stream subscriptions. Watch for race conditions when filter criteria change concurrently with an in-flight location fetch.
Responsibilities
- Fetch mentor locations within map viewport bounds
- Apply availability and specialization filter criteria
- Enforce consent check before returning location data
- Emit state updates to the map view screen
