Issue building with Gradle 8 and RN 0.73.4

[victor-chan-groundswell]

It seems that, when running react native 0.73.4, along with building with gradle 8, I ran into this error message.

A problem occurred configuring project ':amplitude_analytics-react-native'.

com.android.builder.errors.EvalIssueException: defaultConfig contains custom BuildConfig fields, but the feature is disabled.
To enable the feature, add the following to your module-level build.gradle:
android.buildFeatures.buildConfig true

So I went ahead and went down the rabbit hole and looked up a way to enable this....

When I do that, however, then it craps out where on the react native side, with the following error:

A problem occurred evaluating project ':app'.

Failed to apply plugin 'com.facebook.react'.
The value for property 'languageVersion' is final and cannot be changed any further.

I have already flagged this issue on the react-native github, but I'm not sure whether this needs to be looked at on this end or react-natives... either way it does not build correctly.

I'm facing a similar issue when upgrading to RN 0.73.4 as part of upgrading a managed expo app to SDK 50. I was able to fix the BuildConfig issue by adding the lines to this package's android/build.gradle

android {
  // existing code
  buildFeatures {
    buildConfig = true
  }
  // existing code
}

the languageVersion error went away after I regenerated the android directory with expo prebuild --no-install --clean -p android

this patch worked for me -> #617

That patch #617 is not working for me :(
