How to extract the waveform from a file?

[dancb10]

The problem is that this package requires a certain format of the samples you provide to the waveform. The problem is that in your example, you use audiowaveform package to extract the samples. But if we want to use pure flutter and extract these samples from IOS phones for example it's not possible.
Is there a way to extract the samples once we have a .wav file on disk on the phone?
