disableMediationInitialization method

@override Future<void> disableMediationInitialization()

Defers mediation adapter initialization out of initialize — adapters then initialize lazily at the first ad request for their network. Must be called BEFORE initialize (the plugin documents it as a no-op afterwards). Used by AdFlowConfig.deferMediationInit so an app can forward per-network consent signals after UMP settles but before any network SDK spins up (4.0; see doc/MEDIATION_SETUP.md).

Implementation

@override
Future<void> disableMediationInitialization() async {
  disableMediationInitializationCalls++;
  mediationInitDisabledBeforeInitialize ??= initializeCalls == 0;
}
