How can I share voice file(mpeg) which in app files to other app(like whatsapp) in flutter

I tried flutter share 2.0.1 pluggin for share voice file but it did not work(No such file). Could you solve this problem or how can I share voice file to other app? Here is my code and error screenshot.

E/flutter (31567): [ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: PlatformException(assets/voices/pırt.mpeg (No such file or directory), null, null, null)

              onPressed: () {
                try{
                  Share.shareFiles(["assets/voices/pırt.mpeg"],text: "Share");
                }
                catch(ex){
                  print(ex);
                }
              },
            ),

Solution

As the error states, assets/voices/pırt.mpeg is not a valid path to a file on the OS. That's an asset, packaged into your application. If you want to share assets, you need to make them a file on the device first.

You'll need to add the path_provider dependency:

dependencies:
  path_provider: ^2.0.1

Then, make a new File and write the data from the asset to the 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());

This should all go before you share the file. Then when you share the file, use the path of the file object you created:

//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);
}
