Introduction #
A package that utilizes the super awesome flutter_webrtc package to be able to send the screen from one device to another. The package was inspired by a closed Flutter Issue.
This is compatible with all Flutter platforms, including Web, but has only been tested on Android, iOS, MacOS, and Web.
This package provides two examples. One to send the screen and the other to receive the screen.
As a note, this library will not work on simulators or emulators as the underlying frameworks don't exist. You must use a physical device when using this framework.

Setup #
Android #
On Android, you must add three permissions:

android.permission.ACCESS_NETWORK_STATE
android.permission.FOREGROUND_SERVICE
android.permission.SCHEDULE_EXACT_ALARM

Next, within the application tag, you must add the following service:
<service android:name="id.flutter.flutter_background_service.BackgroundService"
android:foregroundServiceType="mediaProjection"
android:enabled="true"
android:exported="false"
tools:replace="android:exported" />

Your AndroidManifest.xml file will now look similar to:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.sender">

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />

<application
android:label="sender"
android:name="${applicationName}"
android:icon="@mipmap/ic_launcher">
<activity
android:name=".MainActivity"
android:exported="true"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:hardwareAccelerated="true"
android:windowSoftInputMode="adjustResize">
<meta-data
android:name="io.flutter.embedding.android.NormalTheme"
android:resource="@style/NormalTheme"
/>
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<service android:name="id.flutter.flutter_background_service.BackgroundService"
android:foregroundServiceType="mediaProjection"
android:enabled="true"
android:exported="false"
tools:replace="android:exported" />

</application>
</manifest>
