FirebaseFlagProvider class final

A FlagProvider backed by Firebase Remote Config.

final provider = FirebaseFlagProvider();
await FlagService.instance.configure(provider);

The fetchInterval governs how frequently refresh will actually hit the network (Firebase enforces a server-side throttle as well). During development you may lower minimumFetchInterval to Duration.zero.
