body: <p><strong>Which audio formats (extensions) work on ios and Android with the just_audio Flutter package?</strong> Wondering which extensions I should allow users to upload with file_picker such that they play with the just_audio package (I couldn't find a list anywhere). To clarify the files will be stored on Firebase therefore played via url.</p>
