To share a simple text, use Share.share() anywhere on our App.

Share.share("Your Text to Share");

below is the same example from Generate Image from Widget Tutorial, but with the added function of sharing the generated Image.

Future<void> takePicture() async {
RenderRepaintBoundary boundary = genKey.currentContext.findRenderObject();
ui.Image image = await boundary.toImage();
final directory = (await getApplicationDocumentsDirectory()).path;
ByteData byteData = await image.toByteData(format: ui.ImageByteFormat.png);
Uint8List pngBytes = byteData.buffer.asUint8List();
File imgFile = new File('$directory/photo.png');
await imgFile.writeAsBytes(pngBytes);
await Share.shareFiles([imgFile.path]);//Sharing the generated Image
