/**
 * A custom Expo plugin to make the Adyen React Native library compatible with Expo SDK 52.
 *
 * The Adyen library currently defines the `onNewIntent` method in Kotlin with a nullable
 * `Intent?` parameter, which is incorrect according to Android's API specifications.
 * This mismatch causes build failures during the `:app:compileDebugKotlin` task.
 *
 * The plugin resolves this issue by replacing the nullable `Intent?` parameter in the
 * `onNewIntent` method with a non-nullable `Intent` parameter in the generated `MainActivity` file.
 *
 * This is a temporary fix while waiting for an official update to the Adyen library
 * that addresses this issue.
 *
 * @see https://github.com/Adyen/adyen-react-native/pull/564
