# Getting Started with Dart

This integration guide is following the Quick Start Guide. We assume that you have fully completed its "Hands-on" path, and therefore can consume the API by browsing this url (opens new window).

If you haven't gone through the Quick Start Guide, the way you request a Strapi API with Dart (opens new window) remains the same except that you will not fetch the same content.

# Create a Dart file

Be sure to have Dart installed (opens new window) on your computer.

take dart-app
touch main.dart

# Use an HTTP client

We'll use http (opens new window) for making HTTP requests.

  • Create a pubspec.yaml file containing the following:
name: my_app
dependencies:
  http: ^0.12.2
  • Install your dependencies by running the following command:
dart pub get

# GET Request your collection type

Execute a GET request on the restaurant Collection Type in order to fetch all your restaurants.

Be sure that you activated the find permission for the restaurant Collection Type.

Request

Map<String,String> headers = {
  'Content-Type':'application/json',
  'Accept': 'application/json'
};

var response = await http.get(
  'http://localhost:1337/restaurants',
  headers: headers
);

print(response.body)

Response

# Example

import 'package:http/http.dart' as http;
import 'dart:convert';

class Restaurant {
  static String api_url = 'http://localhost:1337';
  static Map<String,String> headers = {
    'Content-Type':'application/json',

  restaurant.all();
}

# POST Request your collection type

Execute a POST request on the restaurant Collection Type in order to create a restaurant.

Be sure that you activated the create permission for the restaurant Collection Type and the find permission for the category Collection type.

In this example a japanese category has been created which has the id: 3.

Map<String,String> headers = {
  'Content-Type':'application/json',
  'Accept': 'application/json'
};

var response = await http.post(

  headers: headers,
  body: jsonEncode({

# Conclusion

Here is how to request your Collection Types in Strapi using Dart. When you create a Collection Type or a Single Type you will have a certain number of REST API endpoints available to interact with.
