Usage #
Request #
// https://www.example.com:3000/api/v1/
final resty = Resty(
/// true:https (default if certificate is passed) | false:http (default)
secure: true,
/// load certificate
certificate: await rootBundle.load("assets/certificate.crt"),
/// base-url without http
host: 'www.example.com',
/// secure:443 | not-secure:80 (default)
port: 3000,
/// base path
path: 'api',
/// you can override later in any request
version: 'v1',
/// use to set accept & content-type to `application/json`
json: true,
/// use to enable logger
logger: true,
/// use to send shared headers
headers: {
'foo': 'bar',
},
/// use to specify timeout (default: 30 sec)
timeout: Duration(seconds: 60),
/// listen to request, response and also errors
observers: [
Observer(
onRequest: (request) async {
/// always pass your token before sending request to server
request.headers.add('Authorization', 'Bearer ${YOUR_TOKEN_HERE}');
},
onResponse: (response) {
// TODO
},
onError: (exception) {
// TODO
},
),
],
);

// It as simple as
// https://www.example.com:3000/api/v1/resources
resty.get('resources', query: {'foo': 'bar'});

// you can override your api version whenever you want
// https://www.example.com:3000/api/v2/resources
resty.get('resources', version: 'v2');

You can use any service locator to access resty globally.
For this example we're using get_it.
// models/todo.dart
class Todo {
final int id;
final String title;
final bool compeleted;

Todo.fromMap(Map<String, dynamic> item)
: id = item['id'],
title = item['title'],
compeleted = item['completed'];

static List<Todo> fromList(List<dynamic> items) =>
items.map((item) => Todo.fromMap(item)).toList();
}

// services/todo_service.dart
class TodoService {
final resty = locator<Resty>();

Future<List<Todo>> get all async {
final response = await resty.get('todos');

if (response.isOk) {
return Todo.fromList(response.json);
}

return [];
}
}

// locator.dart
final locator = GetIt.instance;

void setupLocator() {
final resty = const Resty(
secure: true,
host: 'jsonplaceholder.typicode.com',
logger: true,
);

locator.registerLazySingleton(() => resty);
locator.registerLazySingleton(() => TodoService());
}

Then simply use
setupLocator();
final todos = locator<TodoService>().all;
print('${todos.length} todos found!');
