Package to take screenshots in different ways and be able to share them in png format with other applications

Getting Started #

  1. Create Instance of Screenshot Controller
class MyHomePage extends StatelessWidget {
  final TakeScreenshotController _takeScreenshotController = TakeScreenshotController();

  ...
}
  1. Wrap the widget that you want to capture inside TakeScreenshot Widget. Assign the controller to takeScreenshotController that you have created earlier
TakeScreenshot(
    controller: _takeScreenshotController,
    child: WidgetToTakeScreenshot(),
),
  1. Take the screenshot by calling capture method. This print a Uint8List
try {
    final pngBytes = await _takeScreenshotController.captureAsPngBytes();
    print(pngBytes);
} on Exception catch (e) {
    print(e);
}

Full Example:

import 'package:flutter/material.dart';
import 'package:take_screenshot/take_screenshot.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Take Screenshot Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  final TakeScreenshotController _takeScreenshotController = TakeScreenshotController();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter TakeScreenshot Page'),
      ),
      body: TakeScreenshot(
        controller: _takeScreenshotController,
        child: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text(
                'Take your screenshot',
              ),
            ],
          ),
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () async {
          try {
            final pngBytes = await _takeScreenshotController.captureAsPngBytes();
            print(pngBytes);
          } on Exception catch (e) {
            print(e);
          }
        },
        child: Icon(Icons.add),
      ),
    );
  }
}

Saving images to Specific Location #

For this you can use captureAsFile method by passing directory location. By default, the captured image will be saved to Application Directory. Custom paths can be set using path parameter. Refer path_provider

Note #

Method captureAsFile and captureAndShare are not supported for web.
