我尝试使用颤振共享 2.0.1 插件来共享语音文件，但它不起作用（没有这样的文件）。你能解决这个问题或者我如何将语音文件分享到其他应用程序？这是我的代码和错误截图。

              onPressed: () {
                try{

                }
                catch(ex){
                  print(ex);
                }
              },
            ),

正如错误所述，assets/voices/pırt.mpeg它不是操作系统上文件的有效路径。这是一种资产，打包到您的应用程序中。如果您想共享资产，您需要先将它们制作成设备上的文件。

您需要添加 path_provider 依赖项：

dependencies:
  path_provider: ^2.0.1

然后，新建一个File并将数据从资产写入File：

//Get directory and make a file object
final Directory dir = await getTemporaryDirectory();
final File file = File(dir.path + '/mpeg_data');

//Get data from assets
ByteData data = await rootBundle.load('assets/voices/pırt.mpeg');

//Write actual data
await file.writeAsBytes(data.buffer.asUint8List());

这一切都应该在您共享文件之前完成。然后当您共享文件时，使用您创建的文件对象的路径：

//Get directory and make a file object
final Directory dir = await getTemporaryDirectory();
final File file = File(dir.path);

//Get data from assets
ByteData data = await rootBundle.load('assets/voices/pırt.mpeg');

//Write actual data
await file.writeAsBytes(data.buffer.asUint8List());

try{
  Share.shareFiles([file.path],text: "Share");
}
catch(ex){
  print(ex);
}
