Matching tiles using GridView.count
I been thinking about how to implement such a thing and I just can't figure it out. How would you go about implementing a Grid view in which it's items can be selected but it two at a time. If you have a two different lists that have a one to one relationship, how would you check if the selected item is a pair in the other list?I'm thinking it has something to do with checking it's index but I'm a little confused in the algorithm itself. I started programming about 9 months ago and moved to flutter about 4 months ago so I'm not too experienced with this. Will a map be needed?Thanks for any help.

Open Source Flutter Apps
Hi!,For a development course at my university I have to make a report for an open source application made with Flutter. This has to be an app with more than 50k downloads and I am having trouble finding one with that many downloads. Do you know about any application that meets this criteria?

The `rpc_gen` is a builder and generator of RPC (Remote Procedure Call) stub files.
The main goals and purpose of this project:Fast (in minutes) creation of RPC services simultaneously for server and clientFast (in seconds) creation of RPC procedures simultaneously on the server and clientMaximum flexibility in the choice of how to send and handle procedure callsEasily maintenance of consistency of source code for procedures on both layersConventions (of limitations, if you like to call it that):The Request and Response classes must JSON modelsThe JSON models must contain a constructor like formJson(Map json)The JSON models must contain an instance method like Map<String, dynamic> toJson()The RPC methods must be declared like Future<Response> Function(Request)The RPC service metadata class (interface) should contain nothing but methodshttps://pub.dev/packages/rpc_gen

Integration Tests on Windows Love Terminal
Just noting that if you are on MS Windows you still have to execute the drive part via terminal with this:​flutter drive --driver=test_driver/integration_test.dart --target=integration_test/widget_screen_test.dart --host-vmservice-port 8888 > machine.logAnd you get a nice machine.log file afterwards that states in it that the tests passed.Your app run config should have this--host-vmservice-port 8888as additional args​AND! the IntegrationTestWidgetsFlutterBinding.ensureInitialized();line has to be the very first line in main in your widget_screen_test in the integration_test folder as it cannot be in any setup blocksHopefully, Google improves

Discord Server for App Development
Hey everyone. I just quickly wanted to let you know there's a new, fast-growing server generally focused on app development. It's different from the Flutter server in that it is intended to encompass the entire process of building an app from design to development to marketing and more -- but there's also a channel for Flutter help as well. If you're interested in talking to, learning from, and sharing knowledge with like-minded people on the subject of mobile app development, be sure to check it out: https://discord.gg/ZqeGZARx5p

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"}
