Flutter, how to take full screenshot

Question

i am trying to find a way to take a screenshot of entire screen. Flutter library is only allowing me to make a screenshot of a widget, but i want a screenshot of entire android.

I did find this link: How to programmatically take a screenshot on Android?

sadly i am not able to run that code, maybie im making some kind of mistakes? i find a error, while i whas following docs instruction, after that program whas working (not exacly, java whas not able to find my battery, but code whas compiling), and then i copy first answer from that stack link and i tried to pase it in "MainActivity" folder, sadly program whas not working, my "old" java code whas comipilng, from the docs, not the new one.

If you know the solution how to make a photo of entire android screen using some kind of buttor in flutter, or how to implement code from that link into my MainActivity.java folder, please help

Answer 1

Try this package native_screenshot

https://pub.dev/packages/native_screenshot

You can simply run this function to take the screenshot of your phone:

Future<void> _capturePng() async {
    String path = await NativeScreenshot.takeScreenshot();
    print(path);
  }

It work fine with Android and IOS

You can use screenshot plugin:https://pub.dev/packages/screenshot to take a widget screenshot.

A screenshot is a simple plugin to capture widgets as Images. This plugin wraps your widgets inside RenderRepaintBoundary

Use this package as a library

Add this to your package's pubspec.yaml file:

dependencies: screenshot: ^0.2.0 Now in your Dart code, Import it:

import 'package:screenshot/screenshot.dart';

This handy plugin can be used to capture any Widget including full-screen screenshots & individual widgets like Text().

Create Instance of Screenshot Controller

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;
  File _imageFile;

  //Create an instance of ScreenshotController
  ScreenshotController screenshotController = ScreenshotController(); 

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
  }
...
}

Wrap the widget that you want to capture inside Screenshot Widget. Assign the controller to screenshotController that you have created earlier

 Screenshot(
      controller: screenshotController,
      child: Text("This text will be captured as image"),
    ),

Take the screenshot by calling the capture method. This will return a File

screenshotController.capture().then((File image) {
 //Capture Done
 setState(() {
     _imageFile = image;
 });
}).catchError((onError) {
 print(onError);
});
