I've successfully converted to a piano tuner

But sometimes there are exceptions

I'm using flitter 1.22

I reviewed the package and it's really good. There is no special package for frequency in Flutter but it works very well.

But it is not supported in iOS right now, I hope it will work properly on iOS in the future

While using, I find that data has 11 returned variables. I only know the meaning of data[1], data[2] and data[5], but I want to know what do other variables mean? Such like data[4] and data[5].
Thanks.

Let's get more points in pub.dev by fixing the analysis

Any ideas how to resolve ?

This is a very good plugin, hope to see IOS support soon!

I am trying to create an app/website related to audio processing. As said in the title, is it possible to adjust the volume of a specific frequency?

How to make piano tuner

Using this plug-in can't recognize piano key tone normally

Plugin version

flutter doctor

Expected behavior

Actual behavior

Tested environment (Emulator? Real Device?)

Steps to reproduce the behavior

When calling method _async() (based off of example code in repo), nothing happens. Recording doesn't start, no streams opened, data isn't transferred. Tried moving _async() out of the init state and into a button but this didn't affect anything. Any advice?

Plugin version:
