When releasing the flutter apk,,
Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.7.1.
It works well in debug mode and communicates with the API, but the above error continues to occur in release mode. And in this mode, communication with api becomes impossible.
I don’t know if I can’t communicate with api because of the error mentioned above, but I want to solve this error for now.
1.check AndroidManifest.xml : I added ACCESS_NETWROK_STATE option.
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<!-- The INTERNET permission is required for development. Specifically,
the Flutter tool needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
</manifest>
2.check ext.kotlin_version

After setting it up as above,
I tried flutter clean, build and it’s still the same. How can I fix it?
