[Question] Pass as string or File? about record HOT 28 CLOSED

@scheung38 The path which you are getting after recording is actually an Uri. If you want to upload the file then you can do something like this:

    File file = File.fromUri(Uri.parse(filePath));

from record.

Great @amitkhairnar44 thanks! However....what is the exact code? Could you taka a look at my snippet in the second post?
I'm still very puzzled on what exactly should be placed in the "FULL_PATH_TO_AUDIOFILE" part. Would you be so kind to help me out?

from record.

This is partly what i need to....Im trying to email the resulting audio file yet i cant seem to get the variable to get the full path so my mailer can attach the audiofile. Im trying to use this code, maybe you know how or what to put in place of "FULL_PATH_TO_AUDIOFILE"?

mailer() async {
    final smtpServer = SmtpServer("smtp.server.com",
        username: 'username',
        password: 'passwd',
        allowInsecure: true,
        ignoreBadCertificate: true);

    final datumOpmaak = DateFormat('dd-MM-yyyy H:mm');

    // Create our message.
    final message = Message()
      ..from = Address('[email protected]', 'Me')
      ..recipients.add('[email protected]')
      ..subject =
          'Test Dart Mailer library :: 😀 :: ${datumOpmaak.format(DateTime.now())}'
      ..text = 'This is the plain text.\nThis is line 2 of the text part.'
      ..attachments = [
        FileAttachment(File('FULL_PATH_TO_AUDIOFILE'))
          ..location = Location.inline
          ..cid = '<[email protected]>'
      ];

    try {
      final sendReport = await send(message, smtpServer);
      print('Message sent: ' + sendReport.toString());
    } on MailerException catch (e) {
      print('Message not sent.');
      for (var p in e.problems) {
        print('Problem: ${p.code}: ${p.msg}');
      }
    }
  }
// DONE

Hi @bafplus

I think this is the path:

file:///$HOME/Library/Developer/CoreSimulator/Devices/XXXXXXXX-XXXX-XXXX-B3F2-BE4E4FB87E55/data/Containers/Data/Applic
ation/XXXXXXXX-XXXX-XXXX-XXXX-74B3B588FAA4/tmp/XXXXXXXX-XXXX-XXXX-XXXX-1D7571130760.m4a

but I cannot seem to upload .m4a this to Firebase Storage as outlined as it is saying:

'file.absolute.existsSync()': is not true

from record.

Im quite the noob so pardon if i say something stupid or abvious :-)....But isnt that path different on both android and IOS and even per device? If i'm correct the recorder/player is using string, and we are (trying) to use file, maybe thats the issue? So big questions remains...where and how does it store the audiofile and how to get said file to send to firebase (or mail in my case)?

from record.

Hi @bafplus, just copy and paste your filepath found into browser, if it works then thats your audio. But your point is valid, but i have not tried with Android yet, but I can imagine it would be the same path.

from record.

Thats my first problem...i havent found it yet :-)
And in browser? Does that also work in android (i think you are using web?)?

from record.

Working on iOS side, but when we paste into browser we should get:

from record.

Yes but what variable holds that path/url in the first place?
That path is not the same for all devices, so hardcoding will definatly not work. I'm very new to coding in the first place (but learning ;-)) so its very hard for me to pinpoint where and how that path is declared in the first place...

from record.

If you do not provide your own path, path is returned from stop method as uri string. You should try Uri.parse and toFilePath or File.fromUri if you need file handler.

That sounds good...but could you help this noob with some code or example? (see my code above)

from record.

@llfbandit why do we need to parse when we can pass the whole filePath

file:///$HOME/Library/........./XXX.m4a into this:

Future<void> uploadFile(String filePath) async {
  File file = File(filePath);

  try {
    await firebase_storage.FirebaseStorage.instance
        .ref('uploads/file-to-upload.png')
        .putFile(file);
  } on firebase_core.FirebaseException catch (e) {
    // e.g, e.code == 'canceled'
  }
}

from record.

Any luck yet @scheung38 ?

You can use the same code as I have mentioned above.

FileAttachment(File.fromUri(Uri.parse(filePath)))
          ..location = Location.inline
          ..cid = '<[email protected]>'

filePath here would be the path received after recording.

from record.

File.fromUri(Uri.parse(filePath))

Thanks,

Yet i get this error: Undefined name 'filePath'.
If i change it to "Path" it says: The argument type 'Type' can't be assigned to the parameter type 'String'.
If i then make it 'Path as String' i have no errors, but if i try to send it i get: 'Unhandled Exception: type '_Type' is not a subtype of type 'String' in type cast...'

from record.

File.fromUri(Uri.parse(filePath))

filePath should be the path of the file that you are trying to send.

filePath should be the path of the file that you are trying to send.

And thats the problem...we dont know the actual path. It is generated upon recorder_start and put in a variable, yet i dont know what variable exactly or how to (re)call it.

You'll get the path upon stopping the recorder.

Share the code snippet where you're stopping the recorder.

Thanks allot for helping out!

@amitkhairnar44 I have tried different ways yet still without succes, help in any kind is much apriciated :-)

from record.

@bafplus I have checked your code.
In your _MyAppState class you have this code:

AudioRecorder(
              onStop: (path) {
                setState(() {
                  audioSource = ap.AudioSource.uri(Uri.parse(path));
                  showPlayer = true;
                });
              },
            )

You are getting the path in this widget's callback onStop. Assign that path to some variable and use it to upload the file.

Thanks, and that variable would be "audioSource"?

Again, pardon my noobness...im learning here :-)

@bafplus Try this code: https://pastebin.com/nbbkSUk6

@bafplus Try this code: https://pastebin.com/nbbkSUk6

Almost :-)

The named parameter 'path' isn't defined. :236
All final variables must be initialized, but 'path' isn't. :268

from record.

Add it to the constructor like this:

const AudioPlayer({
    required this.path,
    required this.source,
    required this.onDelete,
  });

from record.

Add it to the constructor like this:

const AudioPlayer({
    required this.path,
    required this.source,
    required this.onDelete,
  });

Thats it! many many thanks, you eurned yourself a beer! :-)

This works on emulator but not on device (release.apk)....next stop: permissions :-)

@scheung38 The path which you are getting after recording is actually an Uri. If you want to upload the file then you can do something like this:

    File file = File.fromUri(Uri.parse(filePath));

Unhandled Exception: FileSystemException: Cannot open file, path = 'file:///private/var/mobile/Containers/Data/Application/02XXXXD-7XX3-4XXX-XXXX-3XXXXXXX3/tmp/9XXXXX-5295-XXX-XXXX-XXXX97E8EE2.m4a' (OS Error: No such file or directory, errno = 2) #0 _File.open.<anonymous closure> (dart:io/file_impl.dart:356:9) #1 _rootRunUnary (dart:async/zone.dart:1362:47) #2 _CustomZone.runUnary (dart:async/zone.dart:1265:19) <asynchronous suspension>

I'm getting this error and I just replace this line file = File(path); to file = File.fromUri(Uri.parse(path)); and error solved. Thanks @scheung38
