Modifiyng the lib file to the following adds support to Whatsapp Business app.

  Future<String> shareToWhatsApp(
      {String msg = '', String base64Image = ''}) async {
    final Map<String, Object> arguments = Map<String, dynamic>();
    arguments.putIfAbsent('msg', () => msg);
    arguments.putIfAbsent('url', () => base64Image);
    dynamic result;
    try {
      result = await _channel.invokeMethod('shareWhatsApp', arguments);
    } catch (e) {
      result = "NoWhatsApp";
    }
    if (result=="NoWhatsApp") {
     try {
      result = await _channel.invokeMethod('shareWhatsApp4Biz', arguments);
     } catch (e) {
      result = "NoWhatsApp4Biz";
     }
    }
    return result;
  }

//Update the following in flutter_share_me-0.6.0\android\src\main\java\zhuoyuan\li\fluttershareme

//....
   case "shareWhatsApp":
                msg = call.argument("msg");
                url = call.argument("url");
                shareWhatsApp(url, msg, result);
                break;
            case "shareWhatsApp4Biz":
                msg = call.argument("msg");
                url = call.argument("url");
                shareWhatsApp4Biz(url, msg, result);
                break;
////

//then include the below code at the end

 private void shareWhatsApp4Biz(String url, String msg, Result result) {
        try {
            Intent whatsappIntent = new Intent(Intent.ACTION_SEND);
            whatsappIntent.setType("text/plain");
            whatsappIntent.setPackage("com.whatsapp.w4b");
            whatsappIntent.putExtra(Intent.EXTRA_TEXT, msg);

            if (!TextUtils.isEmpty(url)) {
                FileUtil fileHelper = new FileUtil(registrar, url);
                if (fileHelper.isFile()) {
                    whatsappIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    whatsappIntent.putExtra(Intent.EXTRA_STREAM, fileHelper.getUri());
                    whatsappIntent.setType(fileHelper.getType());
                }
            }
            whatsappIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            activity.startActivity(whatsappIntent);
            result.success("success");
        } catch (Exception var9) {
            result.error("error", var9.toString(), "");
        }
    }

Example Usage:

void sharetoWhatsapp(){
String resultis = await FlutterShareMe().shareToWhatsApp(base64Image: base64string,msg: "text");
if (resultis == 'NoWhatsApp4Biz') {
    print('WHATSAPP & WHATSAPP 4 BUSINESS BOTH APPS NOT INSTALLED');
   }
}

I don't know anything about native android or services.Just it works thats all i know,pls correct the code and update the plugin.
