It’s deprecated Base on the google document
Kotlin Android Extensions is deprecated, which means that using Kotlin
synthetics for view binding is no longer supported.
for those who’s wonder what the synthetic
is. I should say a simple way to access to UI view id with kotlin which was possible by adding 'kotlin-android-extensions'
in Gradle
.
- If your app uses Parcelable you can use
'kotlin-parcelize'
instead of'kotlin-android-extensions'
. - If your app uses Kotlin synthetics for view binding, use this guide to migrate to Jetpack ViewBinding or Data Binding.
