Mastering Feature Flags: Best Practices with Firebase Remote Config
summary
Feature flags are runtime booleans and typed values controlled via Firebase Remote Config to toggle a share button or swap entire screens without rebuilding, and kill switches push updates over an open HTTP connection for near‑real‑time disables. Recommended pattern uses a single injectable wrapper class, ownership and regular cleanup to avoid stale flags. Limits matter: the service caps at 2000 parameters, 300 experiments (24 active), and hourly fetch defaults; follow naming, avoid dependent flags, and remove flags once stable.
