+# pointer_interceptor
+
+`PointerInterceptor` is a widget that prevents mouse events (in web) from being captured by an underlying [`HtmlElementView`](https://api.flutter.dev/flutter/widgets/HtmlElementView-class.html).
+
+You can use this widget in a cross-platform app freely. In mobile, where the issue that this plugin fixes does not exist, the widget acts as a pass-through of its `children`, without adding anything to the render tree.
+
+## What is the problem?
+
+When overlaying Flutter widgets on top of `HtmlElementView` widgets that respond to mouse gestures (handle clicks, for example), the clicks will be consumed by the `HtmlElementView`, and not relayed to Flutter.
+
+The result is that Flutter widget's `onTap` (and other) handlers won't fire as expected, but they'll affect the underlying webview.
+
+|The problem...|
+|:-:|
+|![Depiction of problematic areas](https://raw.githubusercontent.com/flutter/packages/main/packages/pointer_interceptor/doc/img/affected-areas.png)|
+|_In the dashed areas, mouse events won't work as expected. The `HtmlElementView` will consume them before Flutter sees them._|
+
+
+## How does this work?
+
+`PointerInterceptor` creates a platform view consisting of an empty HTML element. The element has the size of its `child` widget, and is inserted in the layer tree _behind_ its child in paint order.
+
+This empty platform view doesn't do anything with mouse events, other than preventing them from reaching other platform views underneath it.
+
+This gives an opportunity to the Flutter framework to handle the click, as expected:
+
+|The solution...|
+|:-:|
+|![Depiction of the solution](https://raw.githubusercontent.com/flutter/packages/main/packages/pointer_interceptor/doc/img/fixed-areas.png)|
+|_Each `PointerInterceptor` (green) renders between Flutter widgets and the underlying `HtmlElementView`. Mouse events now can't reach the background HtmlElementView, and work as expected._|
+
+## How to use
+
+Some common scenarios where this widget may come in handy:
+
+* [FAB](https://api.flutter.dev/flutter/material/FloatingActionButton-class.html) unclickable in an app that renders a full-screen background Map
+* Custom Play/Pause buttons on top of a video element don't work
+* Drawer contents not interactive when it overlaps an iframe element
+* ...
+
+All the cases above have in common that they attempt to render Flutter widgets *on top* of platform views that handle pointer events.
+
+There's two ways that the `PointerInterceptor` widget can be used to solve the problems above:
+
+1. Wrapping your button element directly (FAB, Custom Play/Pause button...):
+
+    ```dart
+    PointerInterceptor(
+      child: ElevatedButton(...),
+    )
+    ```
+
+2. As a root container for a "layout" element, wrapping a bunch of other elements (like a Drawer):
+
+    ```dart
+    Scaffold(
+      ...
+      drawer: PointerInterceptor(
+        child: Drawer(
+          child: ...
+        ),
+      ),
+      ...
+    )
+    ```
+
+### `intercepting`
+
+A common use of the `PointerInterceptor` widget is to block clicks only under
+certain conditions (`isVideoShowing`, `isPanelOpen`...).
+
+The `intercepting` property allows the `PointerInterceptor` widget to render
+itself (or not) depending on a boolean value, instead of having to manually
+write an `if/else` on the Flutter App widget tree, so code like this:
+
+  ```dart
+  if (someCondition) {
+    return PointerInterceptor(
+      child: ElevatedButton(...),
+    )
+  } else {
+    return ElevatedButton(...),
+  }
+  ```
+
+can be rewritten as:
+
+   ```dart
+    return PointerInterceptor(
+      intercepting: someCondition,
+      child: ElevatedButton(...),
+    )
+   ```
+
+Note: when `intercepting` is false, the `PointerInterceptor` will not render
+_anything_ in flutter, and just return its `child`. The code is exactly
+equivalent to the example above.
+
+### `debug`
+
+The `PointerInterceptor` widget has a `debug` property, that will render it visibly on the screen (similar to the images above).
+
+This may be useful to see what the widget is actually covering when used as a layout element.

+# pointer_interceptor_example
+
+An example for the PointerInterceptor widget.
+
+## Getting Started
+
+`flutter run -d chrome` to run the sample. You can tweak some code in the `lib/main.dart`, but be careful, changes there can break integration tests!
+
+## Running tests
+
+`flutter drive --target integration_test/widget_test.dart --driver test_driver/integration_test.dart --show-web-server-device -d web-server --web-renderer=html`
+
+The command above will run the integration tests for this package.
+
+Make sure that you have `chromedriver` running in port `4444`.
