Use case

I am currently working with the Pigeon package in Flutter, where I use enums to define common data types across Swift, Kotlin, and Dart. However, I have encountered an issue with the naming convention for enum cases. Specifically, when using lower camel case for enum cases, Android generates uppercase concatenated strings. As a result, Pigeon currently supports only single-word enum cases.

enum SampleEnum {
  sampleVersion,
  sampleTest,
}

enum class SampleEnum(val raw: Int) {
  SAMPLEVERSION(0),
  SAMPLETEST(1);

  companion object {
    fun ofRaw(raw: Int): SampleEnum? {
      return values().firstOrNull { it.raw == raw }
    }
  }
}

Proposal

I propose implementing a feature in the Pigeon package that supports defining enum cases in lower camel case, resulting in lower camel case conversion for Swift(maintaining the current behavior) and screaming snake case conversion for Kotlin.

In Kotlin, the corresponding generated code should adopt screaming snake case for enum cases.

enum class SampleEnum(val raw: Int) {
  SAMPLE_VERSION(0),
  SAMPLE_TEST(1);

  companion object {
    fun ofRaw(raw: Int): SampleEnum? {
      return values().firstOrNull { it.raw == raw }
    }
  }
}
