I have a Flutter web app that is using the ‘just_audio’ package.

Everything works fine when running locally After I deploy this to Firebase, when I run the same feature the web app throws the following error when it tries to play a ‘mp3’ jusic file.

Uncaught MissingPluginException(No implementation found for method disposeAllPlayers on channel com.ryanheise.just_audio.methods)

The error is related to playing a ‘mp3’ music file. Something else I found a suggestion that this is to do with the web app not having been defined to support ‘mp3’ media files.

However, I can’t find anywhere to configure mp3 support. Any suggestions?
