Create an image from widget (using package)

Sometimes you need to save what a Flutter widget looks like as an image, but without actually showing it on the screen. There's a simple way to do this using a package.

How to Create an Image from a Flutter Widget (Without Showing It)

Here are the easy steps:

1. Get the Right Package

First, you need a package that can do this job. A popular one is the screenshot package.

Add the package

You'll need to add it to your project.

Import it in your code

Once added, you can import it like this:

import 'package:screenshot/screenshot.dart';

2. Take the Screenshot

Now that you have the package, you can use it to capture your widget.

Use the ScreenshotController

You'll use a ScreenshotController to manage the capture.

final controller = ScreenshotController();

Capture the widget

Then, you call the captureFromWidget method. You provide the widget you want to capture. You can also set the size and quality using targetSize and pixelRatio.

final imgBytes = controller.captureFromWidget(
  widget,
  targetSize: const Size(320, 520), // Example size
  pixelRatio: 3, // Example quality
);

This imgBytes variable will hold the image data of your widget.
