Currently, I'm using a flutter screen recorder plugin(https://pub.dev/packages/flutter_screen_recording) to record the screen, Actually, this plugin records the full screen of the mobile.
But my requirement is to record only a particular widget or a particular section of the screen, For example in the video call app there are two users in the screen, I just want to record only the opposite user video only.
So Is there any workaround or solution available for this, Please guide.
There is a fairly new package called screen_recorder that can be used for exactly this.
Here's the example:
ScreenRecorder(
height: 200,
width: 200,
background: Colors.white,
controller: ScreenRecorderController(
pixelRatio: 0.5,
skipFramesBetweenCaptures: 2,
),
child: // child which should be recorded
);
The only downsides are that it can't record platform views like the camera or a Google Maps widget and the recording must have a background color (so you can't record with a transparent background).
I was facing a similar issue while taking screenshots as I was getting a blank or black screen while taking a screenshot. But then using this package solved that problem https://pub.dev/packages/native_screenshot
You can simply run this function to take the screenshot of your stream:
Future<void> _capturePng() async {
String path = await NativeScreenshot.takeScreenshot();
print(path);
}
