New post on /r/flutterdev subreddit: Flutter app’s state in Isolate There are many ways to manage state in Flutter, but most of them are built in such a way that all the logic is executed in the main isolate of your application. Execution of network requests, working with WebSocket, potentially heavy synchronous operations (like local search), all this, as a rule, is implemented in the main isolate. This article shows other doors as well. February 25, 2021 at 10:11PM by congolomera https://ift.tt/3usccx3

New post on /r/flutterdev subreddit: Which database should I use? I am building an app that will be monitoring crypto prices and I have most of it all figured out except this one part of the design. I am doing a callout to binance every 30 seconds and storing the ~ 63 coin prices into their own tables which will later be used by users for graphing purposes. The data stored will just be the symbol, price, and datetime which I estimate is ~30 bytes of data let row. The callout happening every 30 seconds is 2880 callouts per day and 181k rows being written to the db per day. With that being said firebase firestone would cost me $131 per year in writes alone. I think I am leaning towards firebase realtime db since reads and writes don't matter and it's just about the size of download which would just be when a user wants to graph the points, it downloads that coins table.I am building this for myself but am gonna release it to others so I'm not sure how many users there will actually be. So starting out, I want to do this for $0 of possible since it could theoretically only be me that uses it.What other db options are there that would fit my use case here? I looked into aws dynamo db and determined (if I calculated correctly) that my writes would require 126 wcus which would result in something like $500 yearly. There will be other data stored as well but this will be the bulk of it.Thanks for the feedback, really trying to pick the right solution the first time!

New post on /r/flutterdev subreddit: Getting instance of function with parameter Hi, I am beinner in Flutter. I am working on OTP (one time password) authentication and I am struggling to access data which is response from http.post request. When user enters phone number confirmation code is sent and API object called 'secret' is created. User enters phone number from LoginScreen and I should have access 'secret' object from ConfirmationScreenThe problem is when I initialized likeNajotCreateUser najotcreateUser = NajotCreateUser;var secretData = najotcreateUser.createUser()String secret = secretData.data.secretI cant initialize secretData because it has parameter of String phone. My question is how to access instance of createUser() without typing parameter. Below are my code and APIclass NajotCreateUser { Future<User> createUser(String phoneNumber) async { final response = await http.post(url, headers: {"client-id": clientId}, body: jsonEncode(<String, String>{"phone": phoneNumber})); if (response.statusCode == 200) { var result = response.body; var data = User.fromJson(jsonDecode(result)); var secret = data.secret; print('Secret is: '+ secret); return data; } else { var result = response.body; print(result.toString()); return null; } } }This is getting instance of createUserNajotCreateUser najotcreateUser; var secretData = najotcreateUser.createUser('phoneNumber'); /* I have to access to createUser without phoneNumber*/ String secret = secret.data.secret;And this is API"secret": "string","student": {"active": true,"created_at": "string","id": "string","image": { "url": "string", "uuid": "string" },"login_at": "string", "name": "string", "phone": "string", "updated_at": "string"} February 25, 2021 at 08:17AM by Wild-Film673 https://ift.tt/3qTuqoY
