New feature: base64 method #7

Hello, I'm trying to convert signature to base64 but from toImage() I'm not able to convert to base64. I don't know if there is a workaround that permit that. Thank you 👍🏻

Hi, image is returned as ByteData so you need to get raw data firstly -> ByteData.buffer.asUint8List(), then u can use dart:convert package to convert to base64 string.

A little example here:

import 'dart:convert';

final control = HandSignatureControl();
final image = await control.getImage();
final rawData = image.buffer.asUint8List();

final base64String = base64Encode(rawData);
