Two-Ai bd2cb97179 Replace RxJava in DownloadQueue (#9016) ... * Misc cleanup - Replace !List.isEmpty with List.isNotEmpty - Remove redundant case in MoreScreenModel - Drop no-op StateFlow.catch - From lint warning: > SharedFlow never completes, so this operator typically has not > effect, it can only catch exceptions from 'onSubscribe' operator * Convert DownloadQueue queue to MutableStateFlow Replace delegation to a MutableList with an internal MutableStateFlow<List>. In order to avoid modifying every usage of the queue as a list, add passthrough functions for the currently used list functions. This should be later refactored, possibly by inlining DownloadQueue into Downloader. DownloadQueue.updates was a SharedFlow which updated every time a change was made to the queue. This is now equivalent to the queue StateFlow. Simultaneous assignments to _state.value could cause concurrency issues. To avoid this, always modify the queue using _state.update. * Add Download.statusFlow/progressFlow progressFlow is based on the DownloadQueueScreenModel implementation rather than the DownloadQueue implementation. * Reimplement DownloadQueue.statusFlow/progressFlow Use StateFlow<List<T>>.flatMapLatest() and List<Flow<T>>.merge() to replicate the effect of PublishSubject. Use drop(1) to avoid re-emitting the state of each download each time the merged flow is recreated. * fixup! Reimplement DownloadQueue.statusFlow/progressFlow		2023-02-07 22:13:19 -05:00
