iOS issues: Invalid 'tflite_audio.podspec' file after change plugin version and problems with flutter 2

[cmalbuquerque]

I noted that using a new version of this plugin, there are some problems specially in iOS devices:

1. Using the next dependency and running pod install, it fails:

dependencies:
  tflite_audio: ^0.1.6+1

However, using the version 0.1.5+3, this issue not happens!

2. Also, after flutter update to flutter 2, I started to have some problems in startRecording process when running using an iPhone:

If you do NOT see the Flutter application running, it might have crashed. The device logs (e.g. from adb or XCode) might have more details.

Besides this, when running in Android device, it works perfectly both for v0.1.5+3 and v0.1.6+1!

Hi @cmalbuquerque

Many thanks for pointing the bugs out.

1. For the podsec issue, it seems like I’ve forgotten to add an apostrophe after 0.1.6+1 . I’ll have this hot fixed very soon.
2. As for flutter 2.0.0, to be honest I wasn’t aware that this was released just recently. I’ll definitely take a look and see if I can provide a hot fix as well.

Hi @cmalbuquerque

Ive updated the package to 0.1.6+2. Let me know if you still recieve the same error.

@Caldarie yes, it works both on Android and iOS already using Flutter 2! 😁

Many thanks for the update!
