I've tried multiple flutter plug-ins to stream and play and pause music but as of currently, I haven't yet figured out a simple way to implement play and pause, whilst having the ability to avoid music overlapping, I want so that when the current song is playing, if I were to press play on new music track, the current song playing will stop and play the newly pressed song. I've tried flutter_sound, audio player, audio file player, and flute music player but I can't seem to figure out how to do this.
If it is possible either using one of these or a new plug-in, is there a way to implement what I have just described.
The library you seek is more of a multi-track player than a player. Which does not currently exists AFAIK.
The simplest way is to act according to the status of the tracks (which should be given by the player).
Roughly, what I suggest: have something that keeps the status (e.g. paused, playing, completed) of each track. (e.g. List of Tracks) When you press play on track 2 or track 1 finishes playing, you set to 'completed' (or as you wish) the track 1 and set to 'playing' the track 2.
Have a listener on the status of the current track and voila (for autoplay). When the track completes, notify the listener to call a function to start the next one on your list. When you press another track, set to 'completed' the current track and to 'playing' the track you pressed, then notify listeners.
Any library letting you know the status of a track is good enough for your purpose.

I am working on an app that plays audiobooks, and when you click a book in your list a full window player will start playing the book, however when you close/minimize it, I want a miniplayer to show right about the navbar in the bottom. This player has to continue playing from where the first player "stopped" until the user decides to pause.
Im unsure if this can be achieved without having to have both play the audio at the same time? Reason is that when the Fullscreen is closed, player.Dispose is called.
I currently have a function which saves the position of the player and stores it in shared pref, it however cuts the seconds of, so even if I called that in the miniplayer, it wouldnt continue from the same position.
Im new to flutter/dart btw, with only a few months experience. Thanks in advance
You should use a single player and then have two player "widgets" displaying the state of that same player. That way, you don't need to try to stop and start the player - the player can continue playing the whole time while the widgets are the only things changing.
If you're a beginner, the simplest way to define a single player that can be referenced from everywhere is to define it in a global variable, outside of any class declarations (for something more advanced, read about the service locator pattern):
final player = AudioPlayer();
Then let's say you have two widgets to view the state of the same player: FullPlayerWidget and MiniPlayerWidget. They can both reference the same player instance defined above.
Finally, your logic error is that you are calling dispose when minimising the full player widget. You shouldn't do that unless you want the audiobook to stop playing permanently. You don't want it to stop permanently, and you don't even want it to stop at all!
Actually, the only thing you want to happen when minimising is a visual thing. You want to hide the full widget and display the mini widget. But on the audio side, you want the player itself to be unaffected, continuing to play audio as if nothing had happened. Therefore, in this event you should in fact not call any methods on the player.
The best thing you can do as a beginner is to study lots of examples. E.g. podcastproject (although its dependencies are a bit out of date now).
I am developing an app for a radio station using react-native-track-player. I have this working fine. When I press Pause, the player pauses as expected, but when I press Play again the audio continues where it left off on the stream. I would like to effectively "reset" the stream when paused, so that playing again will always pick up the latest audio - like a radio station should as it's live. I tried removing the track using TrackPlayer.remove([trackIndex]) where trackIndex = await TrackPlayer.getCurrentTrack() but this doesn't have the desired effect, it just carries on where the stream paused.
Can anyone help?
Thanks
When you call pause, you can use reset an after add the tracks
Something like that
TrackPlayer.pause();
TrackPlayer.reset();
TrackPlayer.add(track);
I am creating an app that has a playlist and uses the MediaPlayer library. When a song ends I don't want the next song to start. I tried to use the MPMusicPlayerControllerNowPlayingItemDidChangeNotification to pause the music player when the song changes, but the song starts to play before I get the chance to stop it. I also tried to use KVO to track the changes to musicPlayer.currentPlaybackTime, but I only receive messages when i manually change the playback time. I can't find any information about this problem anywhere.
In my app I have shuffle and repeat off, and create a queue with only one song in it, then send that to the music player. When the song finishes, there aren't any other songs in the queue, so it stops playing.
That being said, the latest iOS update has stopped reporting the correct playback state when the song finishes and is reporting it as paused when it used to be stopped. Not sure if that's a side-effect of the above method or not.
Are you calling:
player.beginGeneratingPlaybackNotifications()
before adding the observers?
I'm using MPMoviePlayerViewController and I want to know if there is a method that can tell me when the user clicks on the Pause button for the video, like an observer?
You should use MPMoviePlayerController instead :
Movie Player Notifications
The MPMoviePlayerController class generates numerous notifications to keep your application informed about the state of movie playback. In addition to being notified when playback finishes, interested clients can be notified in the following situations:
When the movie player begins playing, is paused, or begins seeking forward or backward
When the scaling mode of the movie changes
When the movie enters or exits fullscreen mode
When the load state for network-based movies changes
When meta information about the movie itself becomes available
For more information, see the Notifications section in this document.

Is there a way to update the 'listened to' status of an MPMediaItem from the iPod library?
I've tried using MPMusicPlayerController in iPodMusicPlayer mode and it does not mark the podcast as listened to once it finishes playing.
As far as I can see it's not possible to change media attributes from MPMusicPlayer controller.
The only thing you could try play back the podcast and jump to the last second, then play back the last second (and turn the volume to 0 for that second).
But this is no good way as well because, you have play back something this causes a stop of every other iPod playback.
