This commit introduces a significant redesign of the `UserDetailScreen`, transforming it from a simple card-based layout to a more modern and refined profile view. It also replaces the basic list of user posts with a full-featured `PostCardItem` feed.
**Key Changes:**
* **feat(UserDetailScreen):**
* Redesigned the user profile section with a cleaner, borderless layout, moving from a `Card` to a `Column`-based design.
* Enhanced user info display to include email and location as decorative "pills."
* Replaced the previous list of post metadata with a full `PostCardItem`-based feed, showing complete post content directly on the user's profile.
* Added loading skeletons for the profile and post list, as well as an improved empty state for users with no posts.
* Added a "bottom indicator" to signify the end of the post list.
* **refactor(ViewModel):**
* Modified `UserDetailViewModel` to fetch and construct full `PostCard` objects for the user's posts, instead of just `PostMetadata`.
* This involves fetching `PostBody` and `Category` details for each post to provide a rich feed experience.
* **refactor(Shared Element Transition):**
* Introduced `sharedElementPrefix` to `PostCardItem` and `UserDetailScreen` to create unique transition keys for elements (like avatars and names) that appear in multiple screens (e.g., `talk_post_...`, `userdetail_post_...`).
* This ensures that shared element animations are correctly scoped and avoids conflicts when navigating between different feeds and detail screens.
* The shared element transition for user avatar and name now works correctly from any `PostCard` to the `UserDetailScreen`.
* **feat(Repository):**
* Added `getPostBody(postId)` and `getCategory(categoryId)` methods to `UserRepository` to support fetching the detailed data required for constructing `PostCard` objects.
This commit introduces a dedicated user detail screen, enabling users to view profiles, and refactors the navigation flow, particularly for post and image details, to be more modular and robust.
**Key Changes:**
* **feat(UserDetailScreen):**
* Added a new `UserDetailScreen` to display user information, including their avatar, name, bio, and a list of their posts.
* Implemented a `UserDetailViewModel` to fetch user data and their associated posts from the repository.
* The screen is composed of several modular components: `UserDetailCard`, `UserStatsSection`, and `PostsSection`.
* Includes loading skeletons and an empty state for the user's post list.
* Integrated a pull-to-refresh mechanism to update user data.
* **feat(Navigation):**
* Added a new `UserDetail` route (`user_detail/{userId}`) to the navigation graph.
* Users can now navigate from a post card or post detail view to the author's `UserDetailScreen`.
* Clicking a post in the `UserDetailScreen` navigates to the corresponding `PostDetailScreen`.
* **refactor(Navigation & Post/Image Detail):**
* Decoupled the text and image detail views, removing the `PostDetailContainer` that previously managed mode switching with `AnimatedContent`.
* `PostDetailScreen` and `ImageDetailScreen` are now independent navigation destinations.
* Navigation from a post to its image view is now a direct navigation action to `ImageDetailScreen`, simplifying the logic.
* The route for `PostDetail` has been simplified to `post_detail/{postId}`, removing the `mode` parameter.
* **feat(Shared Element Transition):**
* Implemented a shared element transition for the user avatar, animating it from `PostCardItem` to `UserDetailScreen`.
* The avatar transition key is based on `user_avatar_{userId}` for consistent animations.
* **refactor(ImageDetailScreen):**
* Improved the shared element transition for images by setting `placeHolderSize` to `animatedSize` and disabling `renderInOverlayDuringTransition`, which can resolve certain animation artifacts.
* **refactor(Repository):**
* Added `getUserPosts(userId)` to the `UserRepository` to fetch all post metadata for a specific user.
This commit refactors the shared element transitions for images to be more specific and robust, creating a smoother animation between the post list/detail and the full-screen image viewer.
**Key Changes:**
* **Refined Shared Element Keys:**
* The shared element key for images is now based on both `postId` and `imageIndex` (e.g., `post_image_{postId}_{imageIndex}`). This replaces the previous, less specific key (`post_card_{postId}`), ensuring that the correct image animates, especially in multi-image posts.
* **Improved Animation:**
* The animation `tween` duration has been standardized to 400ms with a `FastOutSlowInEasing` curve for a more polished and consistent feel across all image transitions.
* **Navigation & State Handling:**
* The navigation route for `PostDetail` now accepts an `imageIndex` parameter, allowing direct navigation to a specific image within the image detail view.
* The `PostDetailContainer` now uses the passed `initialImageIndex` to correctly display the selected image when entering image mode.
* Shared element transitions are now conditionally applied only during the initial navigation into a mode (text or image) to prevent animation conflicts when switching between them.
* **Component Updates:**
* `PostCardImages` and `PostDetailImages` now accept `sharedTransitionScope` and `animatedContentScope` to correctly apply the shared element modifier to each image.
* `ImageDetailScreen` has been updated to use the new `imageIndex`-based keying for its `ZoomableImage`.
This commit introduces a dedicated image detail screen and integrates it with the post detail view, allowing users to switch between a text-focused layout and an immersive, image-centric one.
**Key Changes:**
* **feat(ImageDetailScreen):**
* Added a new `ImageDetailScreen` for a full-screen, immersive image viewing experience.
* Implemented a `HorizontalPager` to allow swiping between multiple images.
* Included zoom (pinch-to-zoom) and double-tap-to-zoom functionality for images.
* Overlaid post information (author, content snippet) on a blurred background, which can be swiped up to switch back to the text detail view.
* The background is a blurred version of the current image, creating an ambient effect.
* **feat(Navigation):**
* Created a `PostDetailContainer` to manage the animated transition between `PostDetailScreen` (text mode) and `ImageDetailScreen` (image mode).
* Updated the navigation route for `PostDetail` to accept a `mode` parameter (`text` or `image`) to handle deep linking directly into the image view.
* Clicking an image in the feed or post details now navigates to the image mode, preserving the shared element transition.
* **refactor(PostDetail):**
* Modified `PostCardItem` and `PostDetailScreen` to pass both `postId` and the image `index` on image clicks.
* Refactored the image click handler to trigger the navigation to the new image detail mode.
This commit introduces a comprehensive set of features, establishing the core functionality of the application using an MVVM architecture with Hilt for dependency injection.
**Key Changes:**
* **UI & Navigation:**
* Implemented navigation between the main feed, post details, and login screens using Jetpack Navigation Compose.
* Added `TalkScreen` for displaying a feed of posts and `PostDetailScreen` for viewing individual posts and their comments.
* Created a `LoginScreen` with input fields and authentication logic.
* Introduced `PostCardItem` and `CommentItem` Composables for a consistent and reusable UI.
* Added shared element transitions for a smoother user experience when navigating to post details.
* **Architecture & State Management:**
* Integrated Hilt for dependency injection across ViewModels and Repositories.
* Created ViewModels (`TalkViewModel`, `PostDetailViewModel`, `UserViewModel`, `CommentViewModel`, etc.) to manage UI state and business logic.
* Implemented Repository pattern for abstracting data sources from the backend API.
* Defined UI state data classes to ensure a predictable and observable state flow.
* **Data & Models:**
* Introduced data models for `PostCard` and `CommentCard` to aggregate and display complex data structures.
* Added `PostDetailRepository` to orchestrate fetching of post and comment data concurrently.
* Refined DTOs, such as `CreateCommentDto`, for API interactions.
* **Dependencies & Tooling:**
* Added Hilt, Navigation Compose, and Lifecycle ViewModel dependencies.
* Included the `pangu-jvm` library for improved text formatting with spacing between Chinese and English characters.
