Can't get single account stream to work

[jopmiddelkamp]

Hi,

I'm trying to add the single account stream only the EventSource class does not seem te work. You can see that I've added some unit test in the draft PR.

https://github.com/Soneso/stellar_flutter_sdk/pull/60/files

When I run this script while doing the unit test I do see the javascript stream to output the expected data. Only the stream in the unit test only shows the first account reponse event.

var StellarSdk = require('stellar-sdk');
var server = new StellarSdk.Server('https://horizon-testnet.stellar.org');

var accountHandler = function (accountResponse) {
    console.log("");
    console.log("################################");
    console.log("### accountResponse received ###");
    console.log("################################");
    console.log("");
    console.log(accountResponse);
};

var es = server.accounts().accountId("GDUIRZTI6VPHOUIFADD5QFRUVDSQ77K6VHAM76WYVTZ7UIQAR2LCXHFZ").stream({
    onmessage: accountHandler
});

console.log("Stream started");

Is this a known issue?

Hi @jopmiddelkamp thank you for reporting this issue. I will check it next week.

Hi @jopmiddelkamp, currently I don't have issues with the streaming. I added an example (test case) for you in this commit: https://github.com/Soneso/stellar_flutter_sdk/commit/aaef528d8d11c5910aaa4d126f3984d791648a68

You can find it here: https://github.com/Soneso/stellar_flutter_sdk/blob/aaef528d8d11c5910aaa4d126f3984d791648a68/test/account_test.dart#L280

Another example that already existed is here: https://github.com/Soneso/stellar_flutter_sdk/blob/aaef528d8d11c5910aaa4d126f3984d791648a68/test/payments_test.dart#L1027

Hope this helps

Hmm your unit test works so the EventSource seem to be working. I'll change my issue title.

Compared your transactions stream to my account stream and I can't find any difference other then you stream is working and the one I tried to add isn't.. Can you spot anything that I've done wrong maybe?

Hello,

I am not sure what you want to achieve. But I assume you want streaming for the account details. However, this Horizon endpoint does not offer streaming. Instead, I would use transactions streaming for the given account and as soon as a transaction event is received, I would reload the account details (only transactions can change accounts).

See (streaming mentioned): https://developers.stellar.org/api/resources/get-transactions-by-account-id

See (no streaming mentioned): https://developers.stellar.org/api/resources/retrieve-an-account

Ahh ok, I thought that steaming should be available because I saw it in the laboratory combined with the fact that I got a stream going with the JavaScript SDK.

But I'll just create another solution with the transaction stream.

Thanks Christian.
