Starting Flutter App on Everything (ios Sim/Android Emulator/ios Device) Taking Upwards of 30 Mins
Starting the basic "Hello World" app on emulator and simulator takes 30 mins. The fastest is running it on my iPhone 6, but even that took about 15 mins. I'm using VSCode on a late 2014 Mac Mini. Anybody have any tips? My mac mini isn't the greatest but I imagine it's enough to smoothly build Flutter apps, I built Unity games on this same computer.Any help greatly appreciated. Thanks.

Can't Access Cookie in HTTP Response
Hi,I'm working on Flutter an app which will use Express based REST api. While implementing Cookie based sessions, I wanted to retrieve cookies from app with basic auth request but somehow I can't retrieve cookies in response. When I make the same request from Postman, there is no problem, cookies are setted automatically.​I am using HTTP package to make request and code is quite straightforward as below.void login(String username, String password) async {
var url = 'http://$username:$password@111.222.333.444:3333/auth';
var response = await http.get(url);
print('Response header: ${response.headers}');
print('Response status: ${response.statusCode}');
print('Response body: ${response.body}');
}There is no cookie in header or body of response.

<b>future? futurebuilder? I'm struggling just a bit</b>
I've been playing around with flutter. I'm completely new to app development, but I've been building backends in PHP for over a decade now.I'm lost on some of the syntax. The app I'm playing with communicates with some API entry points for an existing site of mine. I've so far been mashing together various examples and failing gracefully a lot. I wanted to see if someone could give me some human friendly explainers on some of the code.My questions are largely from this example: <a href="https://flutter.dev/docs/cookbook/networking/fetch-data">https://flutter.dev/docs/cookbook/networking/fetch-data</a>In step 4, they create the initial call for http data<pre>FutureBuilder<Post>( future: fetchPost(), builder: (context, snapshot) { if (snapshot.hasData) { return Text(snapshot.data.title); } else if (snapshot.hasError) { return Text("${snapshot.error}"); } // By default, show a loading spinner. return CircularProgressIndicator(); }, ); </pre>They call FutureBuilder<Post> - why Post? Is that because they built a future of that previously? Or is Post a reserved word? Since This is getting a JSON object from the web, I am possibly confusing a GET and POST request. I think this is just the naming here. But they called it in the next line, fetchPost(), if they're calling the function, why specify <Post>? I don't fully understand the necessity of those two pieces.Then the builder - What is the context and what is the snapshot? From being able to read the function, it looks like the snapshot gets the data from the JSON request. Context I'm guessing passes on something, but I don't fully get what. Are the names changeable? Instead of snapshop, can I call is 'jsondata'?In the step before that, they create the Future. I don't really get what a Future is or does.<pre>Future<Post> fetchPost() async { final response = await http.get('https://jsonplaceholder.typicode.com/posts/1'); if (response.statusCode == 200) { // If server returns an OK response, parse the JSON. return Post.fromJson(json.decode(response.body)); } else { // If that response was not OK, throw an error. throw Exception('Failed to load post'); } } </pre>I am guessing this is a Future of the Post object they created in the first step. If that's the case, why isn't it part of that object? If it is part of that object, then why does the function name matter? Are there instances where you'd want Future<Post> thisFunction() as well as Future<Post> thatFunction()?The Post class in the previous step has something called a factory. This seems to process some data then feed it back into the object. I'm used to objects having constructors, but a factory is new. Am I correct on my interpretation here?Finally, the way they kick this off is weird to me.<pre>MyApp(post: fetchPost()) </pre>Why are the calling the class by passing it the function? And why are they passing post: fetchPost() and not just fetchPost()? This is why I'm inclined to believe the function name does not make it unique on it's own.Oh and in the MyApp class, what the heck is this?<pre>MyApp({Key key, this.post}) : super(key: key); </pre>I don't understand this. I know we defined a post variable in the class that references the Future<Post>, but I don't really get this. Why not just call the function directly? Can't that be done?I'm sure there are gaps in my knowledge since this isn't what I usually work in. I've been googling a lot and not getting too far. I'm hoping someone can just give me a nice human break down. Any bits of it you care to explain, I'd be happy to read.I can report that I've been working at what feels like a nice pace. I'm working on my login mechanism, already have a data feed that I can display and am deciding what to do next. None of it looks stellar, but I love it. It feels like the first time I ever played with HTML. None of it looks amazing, but I made it, and that makes it amazing. I hope you guys can…

Is there a way to match users based on their location?
Essentially I am hoping to have the app register the location of user A who is actively using the app. Then register the location of user B who is also active and then match them if they are within a 20 mile radius.

Question about ExpansionPanelList Widget in flutter
Hi all,I am building an application where I need to use something like an expansion panel list/radio widget. My functionality is as followsLogin and arrive on a pageThe page contains list of credit card information downloaded from server and each card is labelled by the card's name(Ex: BANK ONE Credit card, Bank Two Credit Card etc)when we click on card the list expands and shows user the card data and and an edit button appears on the header of panel, with which can edit the card information such as address.we can save the information by pressing cancel/save buttons present in the editable widget.My question is ListView in flutter contains a builder constructor with which we can build dynamic lists and reduce memory consumption. However after going through ExpansionPanelList documentation, I do not see anything about building dynamic content. So should I create a custom widget and pass it in a listview.builder method or expansion panel List is optimized to handle large lists?​I appreciate any kind of feedback, thanks!

Finding people/projects to collaborate with/in
Hello everyone, I have been using flutter for a good eight to ten months now and I must say I really enjoy it. Over this time I have worked on some actual projects that are now living the life of 'live apps'. But I am now looking to get more experience in the software developement world and I believe the best option for this is to work in collaboration with other people.Unfortunately I am quite young and do not have anyone intrested in this kind of stuff in my circle of friends.So I wondered if any of you knows of a platform where I could find people looking for other developpers to help them on small to medium sized projects as this would allow me to contact and connect with some people.
