evrone / flutter_audio Goto Github PK

I got this error when I stopped the record. I have no problem when I targeted it on IOS SDK 8.0

Is there a way to manipulate the recorded audio file? (like trimming or reversing the recorded audio file) maybe I can decode the file to raw format do the needed manipulations and encode it back.
any advice?

Migrate of plugin to android X is needed.

https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility

when i use this plugin ,i get error:

startRecorder error: Exception: MissingPluginException(No implementation found for method startRecorder on channel flutter_sound).

but this example run well

Can you please tell me how to retrieve the file path

Hi
final String result = await audioModule.checkMicrophonePermissions();
return no to me
but I'm sure app has permission

Note: C:\Users\Ken\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\medcorder_audio-0.0.1\android\src\main\java\co\medcorder\medcorderaudio\MedcorderAudioPlugin.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Note - I did receive a 'fix' from the author, which I haven't tried, but this needs to be addressed at the project/plugin level.

Need milliseconds, thanks

Is there any plan to migrate this plugin to the latest Android / iOS version?

Can this play from a base64-encoded audio string?

Hello author! Where can I set the recorded audio format to mp4 so that both ios and Android can play this file?

Android works ok, but iOS shows this on init

The following MissingPluginException was thrown while activating platform stream on channel medcorder_audio_events:
MissingPluginException(No implementation found for method listen on channel medcorder_audio_events)

When the exception was thrown, this was the stack:
#0 MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:319:7)

#8 new MedcorderAudio (package:medcorder_audio/medcorder_audio.dart:13:43)
...

needs to be updated to dart 2 preview.

I can't get it to run on Android, it constantly shows No Permissions, which is a bit annoying. Can you please look into this ?

Currently the callback is dynamic which can easily lead to errors at runtime instead of at compile time. It also requires the developer using this library to refer to the readme and copy strings into their codebase, instead of letting the type system handle it.

As an example, you could have a AudioCallback. AudioCallback could have an enum of the event type as one field, and T as the event data.

A different way of doing it could be to have individual callback functions, instead of one where the developer needs to check the type. Eg onRecordingStarted(RecordingStarted event).

This also goes for other parts of the API. Instead of startPlay taking a dynamic map, why not leverage the type system and take:

class StartPlayingArgs {
    String fileId;
    double position;
}

Just when writing that class I already was confused, since in the readme for startPlay it mentions the params should be Map<String, String>, but in the table below it mentions position should be a double. Which is it? Let the type system handle it instead of the readme.

This doesn't even go into the fact that you lose autocomplete if you use dynamic, which also reduces the speed a dev can write code with the library.

I'm trying to play a bit with your plugin but I can't get example running.
Recording seems to be working as I can see feedback with power of microphone,
calling startPlay method returns FAIL.

# Edit:

I found the issue:
there is context assignment missing in plugin java file MedcorderAudioPlugin.java

You just need to update it so it is:

 MedcorderAudioPlugin(Activity _activity) {
    this.activity = _activity;
    this.context = activity.getApplicationContext();
  }
