support tree-shaking native assets when no used dart code references it #130811
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
When building a project which includes a dependency having a native .so library linked via dart:ffi, it will be included in the resulting build even thou calls to that library were removed by tree-shaking dart code.
Expected results
libaudioplayers_linux_plugin.so library is not in the package
Actual results
libaudioplayers_linux_plugin.so library is in the package
Code sample
Code sample
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
import 'package:audioplayers/audioplayers.dart';
import 'constants.dart';
class MyApp extends StatefulWidget {
HomePage createState() => HomePage();
}
const enableAudioplayer = false;
class HomePage extends State<MyApp> {
late var loop;
@override
void initState() {
super.initState();
// loop.ap.play(AssetSource("sound/happy_loop.mp3"));
if (enableAudioplayer) {
initAudioplayer();
}
}
void initAudioplayer() {
loop = AudioPlayer();
// loop = Mgr();
loop.setReleaseMode(ReleaseMode.loop);
loop.play(AssetSource("sound/test.mp3"));
loop.setVolume(0.5);
}
@override
Widget build(BuildContext context) {
return Stack();
}
}
