Goal

Migrate the reaction read responses (getReactions, queryReactions) from the hand-written DTOs to the generated network models.

Part of AND-1291

Implementation

  • Add generated ReactionResponse, GetReactionsResponse and QueryReactionsResponse; remove the hand-written ReactionsResponse and QueryReactionsResponse. sendReaction/deleteReaction keep their hand-written wrapper, their generated responses embed MessageResponse.
  • Add ReactionResponseAdapter so the flattened custom data the v1 endpoints send is collected into custom.
  • Map ReactionResponse to the domain Reaction in DomainMapping. emoji_code is custom data on the backend rather than a declared field (the handler itself reads reaction.Custom["emoji_code"]), so it arrives inside custom; the mapper promotes it to Reaction.emojiCode and filters it out of extraData, matching what the hand-written DTO produced.

Testing

  • ReactionResponseParsingTest covers the response, the nested user and the collected custom fields.
  • DomainMappingTest asserts emoji_code is promoted to emojiCode and does not appear in extraData.
  • Device-probed both endpoints on the wire: sent a reaction carrying emoji_code, then getReactions and queryReactions both returned emojiCode=<emoji> with extraData={}.

Summary by CodeRabbit

  • Bug Fixes

    • Improved reaction retrieval and parsing from chat responses.
    • Preserved custom reaction data, including emoji codes and additional fields.
    • Added support for reaction metadata such as duration and nested user details.
  • Tests

    • Expanded coverage for reaction retrieval, parsing, custom fields, and domain mapping.

Review Change Stack

Walkthrough

The PR replaces legacy reaction response models with network models, adds Moshi parsing for root-level custom reaction fields, maps reactions into domain objects, and updates API fixtures and tests.

Changes

Reaction response migration

Layer / File(s) Summary
Define reaction response models
stream-chat-android-client/src/main/java/io/getstream/chat/android/network/models/*
GetReactionsResponse, QueryReactionsResponse, and ReactionResponse now model reaction responses in the network models package.
Parse and map reaction data
stream-chat-android-client/src/main/java/io/getstream/chat/android/client/parser2/..., stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/mapping/DomainMapping.kt, stream-chat-android-client/src/test/java/io/getstream/chat/android/client/parser2/..., stream-chat-android-client/src/test/java/io/getstream/chat/android/client/api2/mapping/..., stream-chat-android-client/src/test/java/io/getstream/chat/android/client/Mother.kt
ReactionResponseAdapter collects root-level custom fields. Domain mapping converts emoji_code to emojiCode and preserves other custom fields. Parsing and mapping tests cover the new behavior.
Wire the API response type
stream-chat-android-client/src/main/java/io/getstream/chat/android/client/api2/endpoint/MessageApi.kt, stream-chat-android-client/src/test/java/io/getstream/chat/android/client/api2/*
The reactions endpoint and API test fixtures use GetReactionsResponse and the network-model QueryReactionsResponse.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 8f057

The change is merge-ready after normal checks and review; no actionable merge-blocking risk remains. A minor follow-up is to document or narrow the file-level inspection suppressions.

Poem

A rabbit parses fields in the moonlit byte,
Custom sparks hop into maps just right.
Emoji_code becomes a joyful name,
Other data stays within the frame.
New models guide the reactions’ flight,
Tests watch each burrow through the night.
