A simple plugin to capture widgets as Images.
A simple package to capture widgets as Images. Now you can capture widgets that are not rendered on the screen!
This plugin wraps your widgets inside [RenderRepaintBoundary](https://docs.flutter.io/flutter/rendering/RenderRepaintBoundary-class.html)

## Capturing Widgets that are not in the widget tree
You can capture invisible widgets by pr
```dart
screenshotController
.captureFromWidget(Container(
padding: const EdgeInsets.all(30.0),
decoration: BoxDecoration(
border:
Border.all(color: Colors.blueAccent, width: 5.0),
color: Colors.redAccent,

## Saving images to Specific Location
For this you can use captureAndSave 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](https://pub.dartlang.org/packages/path_provider)

## Saving images to Gallery
If you want to save captured image to Gallery, Please use https://github.com/hui-z/image_gallery_saver
Example app uses the same to save screenshots to gallery.
## Note:
### Note:
Captured image may look pixelated. You can overcome this issue by setting value for **pixelRatio**
>The pixelRatio describes the scale between the logical pixels and the size of the output image. It is independent of the window.devicePixelRatio for the device, so specifying 1.0 (the default) will give you a 1:1 mapping between logical pixels and the output pixels in the image.
```dart
double pixelRatio = MediaQuery.of(context).devicePixelRatio;
screenshotController.capture(
pixelRatio: 1.5
pixelRatio: pixelRatio
)
```

......@@ -156,6 +182,6 @@ The solution is to add a small delay before capturing.
screenshotController.capture(delay: Duration(milliseconds: 10))

## Known Bugs
- Image will not be updated if same filename is given multiple times
## Known Issues
- Platform Views are not supported. (Example: Google Maps, Camera etc)
