Any idea? Thanks.

I can't install the app.
I have run "flutter upgrade": flutter version = 1.12.12+hf.8,
Dart - latest,
All packages upgraded via "flutter pub upgrade".

Even tried migrating the app to AndroidX, still fails.

Would be great is there was a way for my recent data table to be synchronised across all my devices.

Maybe some open simple data storage solution. In order to not have a clash on sync all mutations need to go to a queue.
The onboard storage needs to be indempotent so an insert for an already existing row does not fail. This will happen when the mutation ripples to the device it came from.

You could maybe make the db P2P with no cloud by use webrtc. All devices need a global key so each knows all the others

Anyway just brainstorming ideas.

I'm download and import your project in my Mac and try to run with IPhone X .

Message error.

I try to research found flute_music_player not support IOS.

You have any solution?

hello, I just cloned your repo and want to run it but it gives me exceptions seems like you changed a lot of things in flute_plugin song class, if you can share that code too, it'll be very helpful.

Hi,

Since this app is MIT licensed, are you considering the fact to add it to F-Droid? There is a strong community behind.

You can find some documentation here.

Otherwise, if you don't want to work on the inclusion of this app by yourself, would it be ok for you if someone else do it for you?

When playing most of the songs, it gives me this exception.

When I tried developing a music player app with flutter, I had the same issue but removed it by casting the songs var ( which is returned from await MusicFinder.allSongs(); ) to Song class.

I wanted to suggest that you do the same, but then I tried to remove the casting and stick to ( new List.from(songs); ) as before, and it didn't give me this exception anymore, don't know why.

so now I don't actually know what is causing the exception, but you can try my solution and tell me the results, and your conclusions.

Hi

Seems like this project is not working at all , it has a lot of errors inside
could you check that please .

As soon as I play any music it throws this error.
