About feature-flags-flutter
A skill for adding PostHog feature flags to Flutter apps. It favors environment-based keys, minimal code changes, boolean checks by default, and server-side evaluation when possible.
Key features
- 01Add feature flag code to Flutter apps
- 02Keep PostHog keys in environment variables
- 03Prefer boolean flag checks
- 04Favor server-side evaluation when possible
Use cases
- 01Add a boolean flag to a Flutter app
- 02Introduce flags without restructuring existing code
- 03Avoid UI flicker with server-side evaluation
- 04Manage flags through connected PostHog MCP tools
MCP support
When a PostHog MCP server is connected, the skill can use its flag-management tools to create, list, update, or delete flags.

Key principles
- Environment variables: Always use environment variables for PostHog keys. Never hardcode them.
- Minimal changes: Add feature flag code alongside existing logic. Don't replace or restructure existing code.
- Boolean flags first: Default to boolean flag checks unless the user specifically asks for multivariate flags.
- Server-side when possible: Prefer server-side flag evaluation to avoid UI flicker.
PostHog MCP tools
Check if a PostHog MCP server is connected. If available, look for tools related to feature flag management (creating, listing, updating, deleting flags). Use these tools to manage flags directly in PostHog rather than requiring the user to do it manually in the dashboard.
