fun observe(eventHandler: (List<DittoDocument<T>>, DittoLiveQueryEvent<T>) -> Unit): DittoLiveQuery<T>
Enables you to listen for changes that occur on a collection. The eventHandler closure will be
called when local or remote changes are made to documents that match the query generated by the chain
of operations that precedes the call to observe. The returned DittoLiveQuery object must be
kept in scope for as long as you want the provided eventHandler to be called when an update occurs.
fun observe(callback: DittoLiveQueryCallback<T>): DittoLiveQuery<T>
Enables you to listen for changes that occur on a collection. The eventHandler closure will be
called when local or remote changes are made to documents that match the query generated by the chain
of operations that precedes the call to observe. The returned DittoLiveQuery object
must be kept in scope for as long as you want the provided eventHandler to be called when an update
