void pay({ required String partnerId, required String prepayId, required String nonceStr, required String timeStamp, required String sign, dynamic successCall(int code, String prePayId)?, dynamic failCall(int errorCode, String prePayId)?, })

微信支付 partnerId 商户id prepayId 预支付id(由后端调预支付API返回) nonceStr 随机串(由后端返回) timeStamp 时间戳(由后端返回) sign 签名 successCall 微信成功回调,code:0-支付中;1-支付成功; failCall 微信失败回调,errorCode:0-发送支付请求失败;1-支付失败;2-请升级微信客户端;3-未安装客户端;4-用户取消;
