remoteConfigBool method
Boolean feature-flag value for key from the local cache, or
fallback when absent/mistyped. Cache read, never blocks on
network; a stale cache triggers a background refresh, so never call
refreshRemoteConfig from a remote-config-changed listener this can
trigger.
Implementation
Future<bool> remoteConfigBool(String key, bool fallback) => _platform.remoteConfigBool(key, fallback);
