Capacitor Privacy Screen Plugin
## Introduction
⚡️ [Capacitor](https://capacitorjs.com/) plugin that protects your app from displaying a screenshot in [Recents screen](https://developer.android.com/guide/components/activities/recents)/[App Switcher](https://support.apple.com/en-us/HT202070).
On **Android**, this plugin sets the [FLAG_SECURE](https://developer.android.com/reference/android/view/WindowManager.LayoutParams#FLAG_SECURE) flag to treat the content of the window as secure, preventing it from appearing in screenshots or from being viewed on non-secure displays.
On **iOS**, this plugin hides the webview window when the app is no longer active and loses focus ([UIApplicationWillResignActiveNotification](https://developer.apple.com/documentation/uikit/uiapplicationwillresignactivenotification)) so that a gray screen is shown instead. It also prevents screenshots (a black screen will be captured).
### Using the Camera Plugin
Disabling screenshots can interfere with plugins that hide the WebView like the Camera plugin. To avoid issues call `disable` before using a plugin and then `enable` after you are finished.

```
In `capacitor.config.ts`:
```ts
///
import { CapacitorConfig } from '@capacitor/cli';
const config: CapacitorConfig = {

## Demo
A working example can be found here: [robingenz/capacitor-plugin-demo](https://github.com/robingenz/capacitor-plugin-demo)
## Usage
The plugin only needs to be installed. The protection is enabled by default.
However, you have the option to enable/disable the protection:
```js
import { PrivacyScreen } from '@capacitor-community/privacy-screen';
const enable = async () => {
await PrivacyScreen.enable();
};
const disable = async () => {
await PrivacyScreen.disable();
};
```
