Summary of Changes

This pull request integrates robust support for user-defined enums within the firebase-dataconnect library. It provides a flexible EnumValue type that can represent both expected and unexpected enum strings, along with a dedicated serializer. This foundational change prepares the library for future updates where these types will be directly consumed, enhancing API stability and developer experience.

Highlights

• New Enum Value Type: Introduces EnumValue, a sealed interface with Known and Unknown implementations, to gracefully handle recognized and unrecognized enum values, ensuring forward compatibility.
• Kotlinx Serialization Support: Adds EnumValueSerializer for kotlinx.serialization, enabling proper serialization and deserialization of EnumValue objects to and from string representations.

• firebase-dataconnect/CHANGELOG.md
  • Updated with an entry for EnumValue and EnumValueSerializer, indicating their role in replacing code-generated types.
• firebase-dataconnect/api.txt
  • API surface updated to include the new EnumValue sealed interface (with Known and Unknown nested classes) and EnumValueSerializer.
• firebase-dataconnect/gradle.properties
  • Project version incremented to 17.1.0.
• firebase-dataconnect/src/androidTest/kotlin/com/google/firebase/dataconnect/EnumIntegrationTest.kt
  • Integration tests were updated to utilize the new EnumValue types and EnumValueSerializer for deserialization, including new helper functions for enum conversion.
• firebase-dataconnect/src/main/kotlin/com/google/firebase/dataconnect/EnumValue.kt
  • New file defining the EnumValue sealed interface, its Known (for valid enum members) and Unknown (for unrecognized strings) implementations, and their respective properties and methods.
• firebase-dataconnect/src/main/kotlin/com/google/firebase/dataconnect/serializers/EnumValueSerializer.kt
  • New file defining the KSerializer implementation for EnumValue, handling string-to-enum and enum-to-string conversions.
• firebase-dataconnect/src/test/kotlin/com/google/firebase/dataconnect/EnumValueKnownUnitTest.kt
  • Added comprehensive unit tests for the EnumValue.Known class, covering constructor, properties, equality, hash code, string representation, and copy functionality.
• firebase-dataconnect/src/test/kotlin/com/google/firebase/dataconnect/EnumValueUnknownUnitTest.kt
  • Added comprehensive unit tests for the EnumValue.Unknown class, covering constructor, properties, equality, hash code, string representation, and copy functionality.
• firebase-dataconnect/src/test/kotlin/com/google/firebase/dataconnect/serializers/EnumValueSerializerUnitTest.kt
  • Added unit tests for EnumValueSerializer, verifying correct serialization and deserialization of both known and unknown enum values.

• Initial automated comments from github-actions[bot] regarding merging policy.
• Automated reports from google-oss-bot showing a slight decrease in overall coverage (-0.14%) and a minor increase in aar size (+5.60 kB).
• Author dconeybe initiated summary and review generation via /gemini commands.
• gemini-code-assist[bot] suggested using Kotlin data class for EnumValue.Known and EnumValue.Unknown to reduce boilerplate; these suggestions were declined by dconeybe due to Firebase's policy against data class in public APIs to avoid breaking changes.
• Copilot identified and dconeybe resolved typos in TODO comments (visilibity to visibility).
• Copilot pointed out inconsistent rs parameter usage in tests, which dconeybe addressed.
• Copilot provided a nitpick suggestion for multi-line type annotation formatting, which was noted but not explicitly resolved in the provided comments.
