⚡ Jetpack Compose Performance Review

No Jetpack Compose performance issues were found in the changed code.

Audit Summary

The newly introduced and modified code across the touched Kotlin files follows Jetpack Compose performance best practices:

• Jetchat/app/src/main/java/com/example/compose/jetchat/conversation/UserInput.kt:

  • SkipHiddenMarkers is correctly hoisted as a top-level singleton property (private val SkipHiddenMarkers = InputTransformation { ... }), completely preventing unnecessary lambda allocations across composition passes.
  • The markdownStyling OutputTransformation correctly uses remember(codeBackground) with explicit calculation keys, ensuring it is only recomputed when the surface theme color changes.

• Jetchat/app/src/main/java/com/example/compose/jetchat/conversation/RichTextState.kt:

  • The inputTransformation parameter addition in FormattedTextField delegates directly to BasicTextField and chains state.inputTransformation without introducing backwards writes or snapshot overhead.

• Jetchat/app/src/androidTest/java/com/example/compose/jetchat/UserInputTest.kt:

  • Contains Android UI tests verifying text transformations and semantics actions, introducing no composables or UI rendering overhead.

Summary of Reviewed Changes

1. Jetchat/app/src/main/java/com/example/compose/jetchat/conversation/RichTextState.kt:

   • Added an optional inputTransformation: InputTransformation? = null parameter to FormattedTextField and chained it via inputTransformation?.let { state.inputTransformation.then(it) } ?: state.inputTransformation.
   • The operation avoids unnecessary slot-table and remember overhead for lightweight transformations and defaults cleanly to the pre-existing transformation reference when null.

2. Jetchat/app/src/main/java/com/example/compose/jetchat/conversation/UserInput.kt:

   • markdownStyling: Updated OutputTransformation logic executes during text buffer evaluation outside of the Compose composition pass, and the enclosing OutputTransformation remains properly cached with remember(codeBackground).
   • SkipHiddenMarkers: Implemented and hoisted as a top-level singleton val, preventing allocations and lambda captures during composition passes when passed to FormattedTextField.

3. Jetchat/app/src/androidTest/java/com/example/compose/jetchat/UserInputTest.kt:

   • Instrumented Android UI tests validating rich-text marker visibility and cursor behavior; contains no production Compose UI rendering code.
