ContextActivityProvider
A singleton object that helps to maintain a weak reference to the current Activity. This is useful to avoid memory leaks by preventing strong references to an Activity.
The weak reference ensures that the Activity can be garbage collected when no longer in use, preventing holding onto the Activity object longer than necessary.

Sample
Initialize it in your MainActivity.kt class
class MainActivity : ComponentActivity() {
/**
* {@inheritDoc}
*
* If your ComponentActivity is annotated with [ContentView], this will
* call [setContentView] for you.
*/
@CallSuper
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
...
// attach the activity
ContextActivityProvider.setCurrentActivity(this)
...
}Use it in composable methods

fun SomeComposable() {
val activity = ContextActivityProvider.getCurrentActivity()
