lab_sound_flutter's Issues

General Enquiry about Miniaudio

Hello @xioxin

Hope you are doing well. I recently started to play around with ffigen, found it very interesting.
I just know the basics of C, not in depth. Next, i decided to port the library https://miniaud.io/

I was able to generate the bindings, but when I started to use it, it gave me an error. Probably, I think I need to create a wrapper over the generated bindings.

But, I am finding it difficult (although not impossible :p), started searching over the net and found your repository has a tag of miniaudio. I wanted to know how are you using miniaudio in your project.

I didn't know how to connect with you, hence filing an issue. In case you are interested to connect, on git or any other platform, kindly let me know.....

AudioBufferSourceNode

Hi everybody.
I have a stupid question :
How can I create an AudioBufferSourceNode ?
Is there somewhere a table with how the W3C recommandation match the LabSound_flutter library?
Thank you guys /girls and others. Take care.

How to add this to my Flutter project? (Error: "Could not find a file named "pubspec.yaml" in")

Hi @xioxin! Thanks for creating this repo and making it public.

Can I use it in my projects? If yes, how can I use it?

I have searched pub.dev but couldn't find a package of this repo.

I have tried adding it to my project's pubspec.yaml file like this:

  lab_sound_flutter:
    git:
      url: https://github.com/xioxin/lab_sound_flutter   #also with .git suffix
      ref: main   #or a commit hash like f89e1a5

However, I am getting this error:

Could not find a file named "pubspec.yaml" in 
"/Users/yasinarik/.pub-cache/git/lab_sound_flutter-f89e1a56a223e3f61b3b1bda51818578be01e237".

pub get failed (66; Could not find a file named "pubspec.yaml" in "/Users/yasinarik/.pub-cache/git/lab_sound_flutter-f89e1a56a223e3f61b3b1bda51818578be01e237".)
exit code 66

Could you please help?

Example project gives error: "Failed to lookup symbol 'InitDartApiDL': dlsym(RTLD_DEFAULT, InitDartApiDL): symbol not found"

Hi @xioxin . Thanks for resolving my previous flutter pub get issue.

I am having another difficulty so I opened this dedicated issue here.
Currently, I am trying the example project on the iOS simulator. However, all the example pages of the app give this error:
