use RenderRepaintBoundary

var repaintScreen = new GlobalKey();

//this for which part you want to take a screen shot or say capture in image

RepaintBoundary(
  key: repaintScreen,
  child: Container(
  )
),

RenderRepaintBoundary boundary =
    repaintScreen.currentContext.findRenderObject();

prefix0.Image image = await boundary.toImage();
final directory = (await getApplicationDocumentsDirectory()).path;
ByteData byteData =
    await image.toByteData(format: prefix0.ImageByteFormat.png);
Uint8List pngBytes = byteData.buffer.asUint8List();
print(pngBytes);
File imgFile = new File('$directory/poct.jpeg');
imgFile.writeAsBytes(pngBytes);
