native_screenshot_ext

Description:

native screenshot ext

native_screenshot #
This plugin aims to be a simple one that implements taking screenshot natively to capture scenes like camera preview or AR views. This cannot be done easily in plain Flutter, at least I cannot make it work using RenderRepaintBoundary and similar techniques.
The main difference with another packages is that they shows a share dialog. This plugin saves the image and returns the path to it. On Android also launch an updating request (internally) to reload the media library.
Instalation #
Add
native_screenshot: ^<latest_version>

to your pubspec.yaml file.
Android #
You must add
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

to your AndroidManifest.xml inside android/src/main/ directory.
Also you need to add a property to application tag to fix an issue with permissions writing to EXTERNAL_STORAGE:
android:requestLegacyExternalStorage="true"
copied to clipboard
iOS #
If don't add
<key>NSPhotoLibraryAddUsageDescription</key>
<string>Take pretty screenshots and save it to the PhotoLibrary.</string>
copied to clipboard
to your info.plist file inside ios/Runner directory, the application will crash.
Use #
Import the library:
import 'package:native_screenshot_ext/native_screenshot_ext.dart';
copied to clipboard
and take a screenshot:
String path = await NativeScreenshot.takeScreenshot()
copied to clipboard
In error case the function returns null and the screenshot path if success.
