flutter - Image clipped outside the height and width

Question

I am trying to generate an image from Picture rendered from Canvas. When I apply height and width then this image clipped and particular area generated. I want to resize the over all image and generate file from this.

Here is my code:

//Generate Thumbnail
ui.Image thumbnail = await picture.toImage(200, 120,);
ByteData thumbByteData = await thumbnail.toByteData(format: ui.ImageByteFormat.png, );
Uint8List thumbBytes = thumbByteData.buffer.asUint8List();

final resultThumbnail = await ImageGallerySaver.saveImage(
  Uint8List.fromList(thumbBytes)
  quality: 100,
  name: "${DateTime.now().millisecondsSinceEpoch}",
  isReturnImagePathOfIOS: true,
);
