+Use the Flutter Widget Previewer to render widgets in real-time, isolated from the full application context.
 
 - **Target Elements:** Apply the `@Preview` annotation to top-level functions, static methods within a class, or public widget constructors/factories that have no required arguments and return a `Widget` or `WidgetBuilder`.
 - **Imports:** Always import `package:flutter/widget_previews.dart` to access the preview annotations.
-- **Custom Annotations:** Extend the `Preview` class to create custom annotations that inject common properties (e.g., themes, wrappers) across multiple widgets.
+- **Custom Annotations:** Extend the `Preview` class to create custom annotations that inject common properties (e.g., custom themes, wrappers, sizes) across multiple widgets.
 - **Multiple Configurations:** Apply multiple `@Preview` annotations to a single target to generate multiple preview instances. Alternatively, extend `MultiPreview` to encapsulate common multi-preview configurations.
-- **Runtime Transformations:** Override the `transform()` method in custom `Preview` or `MultiPreview` classes to modify preview configurations dynamically at runtime (e.g., generating names based on dynamic values, which is impossible in a `const` context).

+
+## Preview Parameters
+
+The `@Preview` annotation supports the following parameters for tailoring preview environments:
+
+- `name`: A descriptive name for the preview instance.
+- `group`: A name used to group related previews together in the previewer.
+- `size`: Artificial constraints using a `Size` object.
+- `textScaleFactor`: Custom font scale factor.
+- `wrapper`: A function that wraps the previewed widget in a specific widget tree (e.g., to inject state or inherited widgets).
+- `theme`: A function returning a `PreviewThemeData` subclass instance to provide custom theming with support for sequential theme layering.
+- `brightness`: The initial theme `Brightness` (`Brightness.light` or `Brightness.dark`).
+- `localizations`: A function applying a localization configuration.
 
 ## Handling Limitations
 
 Adhere to the following constraints when authoring previewable widgets, as the Widget Previewer runs in a web environment:
 
-- **No Native APIs:** Do not use native plugins or APIs from `dart:io` or `dart:ffi`. Widgets with transitive dependencies on `dart:io` or `dart:ffi` will throw exceptions upon invocation. Use conditional imports to mock or bypass these in preview mode.

 - **Asset Paths:** Use package-based paths for assets loaded via `dart:ui` `fromAsset` APIs (e.g., `packages/my_package_name/assets/my_image.png` instead of `assets/my_image.png`).
 - **Public Callbacks:** Ensure all callback arguments provided to preview annotations are public and constant to satisfy code generation requirements.
-- **Constraints:** Apply explicit constraints using the `size` parameter in the `@Preview` annotation if your widget is unconstrained, as the previewer defaults to constraining them to approximately half the viewport.

+- **Build Caching:** The previewer caches builds in a `.widget_preview/` folder in the project root.

 - [ ] Import `package:flutter/widget_previews.dart`.
 - [ ] Identify a valid target (top-level function, static method, or parameter-less public constructor).
 - [ ] Apply the `@Preview` annotation to the target.
-- [ ] Configure preview parameters (`name`, `group`, `size`, `theme`, `brightness`, etc.) as needed.

 ### Interacting with Previews
 Follow the appropriate conditional workflow to launch and interact with the Widget Previewer:
 
-**If using a supported IDE (Android Studio, IntelliJ, VS Code with Flutter 3.38+):**
+**If using a supported IDE (Android Studio, IntelliJ, VS Code with Flutter 3.47+):**
 1. Launch the IDE. The Widget Previewer starts automatically.
 2. Open the "Flutter Widget Preview" tab in the sidebar.
-3. Toggle "Filter previews by selected file" at the bottom left if you want to view previews outside the currently active file.
+3. Toggle "Filter previews by selected file" at the bottom of the environment to switch between showing only previews in the active file vs. project-wide previews.
 
 **If using the Command Line:**
 1. Navigate to the Flutter project's root directory.
 2. Run `flutter widget-preview start`.
-3. View the automatically opened Chrome environment.
-
-**Feedback Loop: Preview Iteration**
-1. Modify the widget code or preview configuration.
-2. Observe the automatic update in the Widget Previewer.
-3. If global state (e.g., static initializers) was modified: Click the global hot restart button at the bottom right.
-4. If only the local widget state needs resetting: Click the individual hot restart button on the specific preview card.
-5. Review errors in the IDE/CLI console -> fix -> repeat.
+3. View the automatically launched real-time preview environment in the browser.
+
+**Searching and Filtering:**
+- Use the search bar at the top of the preview environment to filter previews in real-time.
+- Use the filter dropdown to match against:
+  - **Preview name**: Filter by preview `name`.
+  - **Group name**: Filter by preview `group`.
+  - **Containing script**: Filter by the URI of the Dart file containing the preview.
+  - **Containing package**: Filter by the package name.
+
+**Feedback Loop: Preview Controls & Iteration**
+1. Inspect the preview using card controls:
+   - **Zoom in / Zoom out / Reset zoom**: Adjust preview magnification.
+   - **Toggle light/dark mode**: Switch color scheme.
+   - **Preview hot restart**: Restart only the specific widget preview to apply local changes quickly.
+2. Modify widget code or preview configurations.
+3. If global state was modified (e.g., static initializers changed): Use the global hot restart button at the bottom right of the previewer.
