onDetachedFromTarget property Null safety

Stream<DetachedFromTargetEvent> onDetachedFromTarget

Issued when detached from target for any reason (including detachFromTarget command). Can be issued multiple times per target if multiple sessions have been attached to it.

Implementation

Stream<DetachedFromTargetEvent> get onDetachedFromTarget => _client.onEvent
    .where((event) => event.name == 'Target.detachedFromTarget')
    .map((event) => DetachedFromTargetEvent.fromJson(event.parameters));
