Walkthrough

Integrates Hilt dependency injection into the Kotlin Multiplatform Compose sample application by adding Hilt and KSP plugins to the build configuration, updating dependencies, establishing the Hilt entry point via a custom Application class, and creating a sample screen demonstrating Hilt-based ViewModel injection. Additionally updates the navigation framework's view model store ownership handling and refactors retained values store implementation.

📝 Customizable high-level summaries are now available in beta!

You can now customize how CodeRabbit generates the high-level summary in your pull requests — including its content, structure, tone, and formatting.

• Provide your own instructions using the high_level_summary_instructions setting.
• Format the summary however you like (bullet lists, tables, multi-section layouts, contributor stats, etc.).
• Use high_level_summary_in_walkthrough to move the summary from the description to the walkthrough section.

Example instruction:

"Divide the high-level summary into five sections:

1. 📝 Description — Summarize the main change in 50–60 words, explaining what was done.
2. 📓 References — List relevant issues, discussions, documentation, or related PRs.
3. 📦 Dependencies & Requirements — Mention any new/updated dependencies, environment variable changes, or configuration updates.
4. 📊 Contributor Summary — Include a Markdown table showing contributions: | Contributor | Lines Added | Lines Removed | Files Changed |
5. ✔️ Additional Notes — Add any extra reviewer context. Keep each section concise (under 200 words) and use bullet or numbered lists for clarity."
