It takes a URL which is the URL path (endpoint), data which is the request data, and options that contain the HTTP method and the headers.Īnd lastly, we created a method to handle errors. Next, we create a method called request, which uses the instance of the Dio( _dio) to call the Dio request method that allows us to make HTTP calls with options. Set the connection Time out, receive Time out and an Interceptor (which is the LoggingInterceptor class we created above) We have passed in the headers, where we have defined the content type we want to receive. The BaseService classĬreate a dart file named logger.dart and create a class called LogginInterceptor that will extend the Interceptor class from the Dio package.Ĭlass LoggingInterceptor extends Interceptor įirst, we created an instance of Dio named _dio. This folder will contain classes that enable the application to make network calls over the HTTP to access resources from a backend server. The class contains instance variables, the constructor for initializing the fields on object creation, and methods that will convert the JSON that we receive from the API into Dart Classes. from(weather.map((x) => x.toJson())),įactory omJson(Map json) => Clouds(įactory omJson(Map json) => Coord(įactory omJson(Map json) => Main(įeelsLike: json.toDouble(),įactory omJson(Map json) => WeatherElement(įactory omJson(Map json) => Wind( String weatherToJson(Weather data) => json.encode(data.toJson()) įactory omJson(Map json) => Weather( Weather weatherFromJson( String str) => omJson(code(str)) final weather = weatherFromJson(jsonString) First, create a dart file called weather_model.dart as shown below. In the model folder, we will create a class representing the object we will receive from the server.

Utilities (components we want to reuse).

Service (classes that allow us to make network calls).Model (Object Representation of the data).The project is being structured in this order: The dependencies section of your pubspec.yaml file should look like this. The geolocator allows us to easily access platform-specific locations, while the flutter Spinkit gives us a collection of loading indicators. In addition, add the geolocator dependency geolocator: ^7.7.0 and flutter spinkit dependency flutter_spinkit: ^5.1.0.

If you don’t know how to use the GetX package for state management in flutter read my article on Getx. Then, run the command pub get to sync the dependency in the project.Īlso add Getx and Get Storage for state management and local storage respectively. To add the Dio package as a dependency into the application, go to the Dio Documentation, copy dio: ^4.0.0, and add it to the project’s pubspec.yaml file. Next, fill in the project details in the image below and click finish. Ensure that you set the type as Flutter application, and select the path where your Flutter SDK is located, then click next.

How to access the geolocation of a user.

How to use the Dio package for network calls.Flutter GetX package will be used for state management however, emphasis is on Dio and network calls. The app requests the user’s location and returns weather information about the user’s current location. We will be building a weather app that provides real-time weather information by making a network call to a weather API. This article will walk the reader through how to consume a REST API in a flutter application using the Dio package.
