captureFromWidget method
Future<Uint8List>
captureFromWidget(
- Widget widget, {
- Duration delay = const Duration(seconds: 1),
- double? pixelRatio,
- BuildContext? context,
- Size? targetSize,
Value for delay
should increase with widget tree size. Prefered value is 1 seconds
context
parameter is used to Inherit App Theme and MediaQuery data.
Implementation
Future<Uint8List> captureFromWidget(
Widget widget, {
Duration delay: const Duration(seconds: 1),
double? pixelRatio,
BuildContext? context,
Size? targetSize,

ui.Image image = await widgetToUiImage(widget,
delay: delay,
pixelRatio: pixelRatio,
context: context,
targetSize: targetSize);
final ByteData? byteData =
await image.toByteData(format: ui.ImageByteFormat.png);
image.dispose();
return byteData!.buffer.asUint8List();
