# snapshot_widget
[](https://pub.dartlang.org/packages/snapshot_widget)
A Flutter library to Snapshot Widget to Uint8List image.
## Features
- Snapshot Widget
```dart
final _controller = SnapshotsController();
SnapshotsWidget(
controller: _controller,
child: Container(),
)
```
- Snapshot widget to Uint8List
```dart
final imageBytes = await _controller.value(pixelRatio: 16 / 9);
```
## Getting started
It is really easy to use! You should ensure that you add the `snapshot_widget` as a dependency in your flutter project.
```yaml
snapshot_widget: "^1.0.1"
```
## Usage
```dart
class _MyAppState extends State {
final _controller = SnapshotsController();
Uint8List _image = Uint8List.fromList([]);
@override
Widget build(BuildContext context) {
return Column(
children: [
SnapshotsWidget(
controller: _controller,
child: const SmartCardWidget(),
),
OutlinedButton(
onPressed: _SnapshotsWidget,
child: const Text('Snapshot'),
),
const Divider(),
if (_image.isNotEmpty)
Image.memory(_image),
],
);
}
void _SnapshotsWidget() async {
final imageBytes = await _controller.value(pixelRatio: 16 / 9);
setState(() {
_image = imageBytes;
});
}
}
```
