Greptile Overview

Greptile Summary

Added dependsOn support to the Dropdown component to enable dynamic option refetching when dependent fields change, specifically when credentials are updated in Gmail and Outlook triggers.

• Implemented dependency tracking in dropdown.tsx using useSubBlockStore to monitor changes in dependent field values
• Added a new effect (lines 303-317) that clears fetched options when dependency values change, triggering a refetch
• Passed dependencyValues to the fetch effect (line 339) to ensure options are refetched when dependencies update
• Applied dependsOn: ['triggerCredentials'] to Gmail labels and Outlook folders dropdowns so they refetch when credentials change

The implementation follows a clean pattern: when a user selects new credentials, the dependency tracking detects the change, clears the existing options, and automatically fetches fresh options using the new credential.

Confidence Score: 4/5

• This PR is safe to merge with minor considerations around edge case handling
• The implementation is sound and follows React best practices with proper use of useEffect, useCallback, and dependency arrays. The change is well-contained and adds important functionality for dynamic option fetching. Score of 4 (not 5) due to one consideration: the dependency tracking initializes previousDependencyValuesRef with an empty string, which means the first render comparison (line 309) will always detect a change if there are dependencies, potentially causing an unnecessary clear of options on mount
• The dropdown component (dropdown.tsx) should be tested thoroughly with different dependency scenarios to ensure the refetch behavior works correctly in all cases
