Check if developer mode is enabled in a native Android module - react-native

Question

I am working on a native Android module for my React Native app. I would like to check if the developer mode is enabled and turn web content debugging in WebView on or off accordingly.
Here's what I tried:
boolean devSupportIsEnabled;
ReactActivity reactActivity = (ReactActivity) getModule().getActivity();
if (reactActivity != null) {
devSupportIsEnabled = reactActivity
.getReactInstanceManager()
.getDevSupportManager()
.getDevSupportEnabled();
} else {
devSupportIsEnabled = false;
}
Unfortunately, this does not compile because ReactActivity.getReactInstanceManager() is protected.
There is also the ReactBuildConfig.DEBUG property, but it is always false for some reason.
Are there any alternative ways?

An instance of ReactInstanceManager can be obtained by the package if it inherits from ReactInstancePackage:
public class MyPackage extends ReactInstancePackage {
#Override
public List<NativeModule> createNativeModules(ReactApplicationContext reactContext, ReactInstanceManager reactInstanceManager) {
// store the provided instance of ReactInstanceManager
this.reactInstanceManager = reactInstanceManager;
// ...
}
//...
}
This instance can be used later to check whether the dev mode is enabled:
boolean devModeIsEnabled = this.reactInstanceManager
.getDevSupportManager()
.getDevSupportEnabled();
