How to solve : Error: Getter not found: 'skippingToNext'. ? AudioProcessingState.skippingToNext in flutter?

Question

I encounter an error that I don't know how to solve, when I try to do a flutter build ipa, I get the following error :

[!] CocoaPods could not find compatible versions for pod "native_webview":
  In Podfile: native_webview (from `.symlinks/plugins/native_webview/ios`)

Specs satisfying the `native_webview (from `.symlinks/plugins/native_webview/ios`)` 

dependency were found, but they required a higher minimum deployment target.

in my Podfile i have :

# Uncomment this line to define a global platform for your project
platform :ios, '10.12.2'

if i put lower version, webview error is solved but another error from audio library : https://pub.dev/packages/audio_service/versions/0.15.3 appears because this one requires above platform version ('10.12.2') to work.

So how can i manage it to works please ? someone may have experience on same issue?

Thank you
