NetworkUsageViewModel

class NetworkUsageViewModel(dispatchersProvider: DispatchersProvider, val observeNetworkUsageUseCase: ObserveNetworkUsageUseCase, val resetNetworkUsageUseCase: ResetNetworkUsageUseCase, val router: NetworkUsageRouter, val onError: (Throwable) -> Unit = {}) : BaseMviViewModel<NetworkUsageState, NetworkUsageIntent, EmptyEffect> (source)

ViewModel for the standalone network usage screen.

It subscribes to persisted traffic counters through ObserveNetworkUsageUseCase so the screen updates when Ktor calls or model downloads report bytes. Resetting statistics clears Room data and briefly switches to the shimmer state while the new zero snapshot is emitted.
