there's no way to use dart3 incompatible package?

Question

I'm beginner for android developer. (for fun) I want to make sheet music quiz app with flutter. so I tried to find sheet music render package.

I found two package (piano, sheet_music)

But

• sheet_music package - dart3 incompatible
• piano package - only show me interative piano.

Q1. how can i use dart3 incompatible package?

Q2. or can i render sheet music with piano package?

piano package's basic usage is

return CupertinoApp(
        title: 'Piano Demo',
        home: Center(
          child: InteractivePiano(...

---

so i changed

return CupertinoApp(
      title: 'Piano Demo',
      home: Center(
        child: ClefImage(
          clefColor: Colors.white,
          clef: Clef.Treble,
          noteColor: Colors.white,
          noteImages: [NoteImage(notePosition: NotePosition(note: Note.C, octave: 4),),],
          noteRange: NoteRange(
            NotePosition(note: Note.C, octave: 4),
            NotePosition(note: Note.C, octave: 5),
          ),
        ),
      ),
    );

i'm expect 5 lines sheet music. but i only got black screen
