Describe the bug
I am encountering an issue when trying to build my Android project. The error states that it cannot resolve the dependency com.google.android:flexbox:1.0.0.

Looks like a lot of old packages were removed from jcenter archives. You can fork the project and bump up the flexbox dependency from 1.0.0 to 3.0.0 in the build.gradle file:

implementation "com.google.android.flexbox:flexbox:3.0.0"

also add the google maven repo https://maven.google.com in the project build.gradle file:

allprojects {
    repositories {
        jcenter()
        google()
        maven { url "https://jitpack.io" }
        maven { url "https://maven.google.com"}
    }
}

Make a aar release build and include that instead of the current chatkit dependency, I also needed to add the flexbox dependency to the project using chatkit.
