# Getting Started with Dart

✋ CAUTION

This third-party integration guide might not be up-to-date with Strapi v4. Contributions (opens new window) are most welcome.

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.

Example GET 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)

Example response

[
  {
    "id": 1,
    "name": "Biscotte Restaurant",
    "description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers.",
    "created_by": {
      "id": 1,
      "firstname": "Paul",
      "lastname": "Bocuse",
      "username": null
    },
    "updated_by": {
      "id": 1,
      "firstname": "Paul",
      "lastname": "Bocuse",
      "username": null
    },
    "created_at": "2020-07-31T11:37:16.964Z",
    "updated_at": "2020-07-31T11:37:16.975Z",
    "categories": [
      {
        "id": 1,
        "name": "French Food",
        "created_by": 1,
        "updated_by": 1,
        "created_at": "2020-07-31T11:36:23.164Z",
        "updated_at": "2020-07-31T11:36:23.172Z"
      }
    ]
  }
]

# 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',
    'Accept': 'application/json'
  };

  void all() async {
    var response = await http.get('${api_url}/restaurants', headers: headers);
    print(response.body);
  }
}

void main() {
  var restaurant = Restaurant();
  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.

Example POST request

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

var response = await http.post(
  'http://localhost:1337/restaurants',
  headers: headers,
  body: jsonEncode({
    'name': 'Dolemon Sushi',
    'description': 'Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious.',
    'categories': [3]
  });
);

Example response

{
  "id": 2,
  "name": "Dolemon Sushi",
  "description": "Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious",
  "created_by": null,
  "updated_by": null,
  "created_at": "2020-08-04T09:57:11.669Z",
  "updated_at": "2020-08-04T09:57:11.669Z",
  "categories": [
    {
      "id": 3,
      "name": "Japanese",
      "created_by": 1,
      "updated_by": 1,
      "created_at": "2020-07-31T11:36:23.164Z",
      "updated_at": "2020-07-31T11:36:23.172Z"
    }
  ]
}

# 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',
    'Accept': 'application/json'
  };

  void all() async {
    var response = await http.get('${api_url}/restaurants', headers: headers);
    print(response.body);
  }

  void create(name, description, category) async {
    final data = jsonEncode({
      'name': name,
      'description': description,
      'categories': category
    });

    var response = await http.post(api_url, headers: headers, body: data);
  }
}

void main() {
  var restaurant = Restaurant();
  restaurant.create(
    'Dolemon Sushi',
    'Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious.',
    [3]
  );
}

# PUT Request your collection type

Execute a PUT request on the restaurant Collection Type in order to update the category of a restaurant.

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

Example PUT request

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

var response = await http.put(
  'http://localhost:1337/restaurants/2',
  headers: headers,
  body: jsonEncode({
    'categories': [2]
  });
);

Example response

{
  "id": 2,
  "name": "Dolemon Sushi",
  "description": "Unmissable Japanese Sushi restaurant. The cheese and salmon makis are delicious",
  "created_by": null,
  "updated_by": null,
  "created_at": "2020-08-04T10:21:30.219Z",
  "updated_at": "2020-08-04T10:21:30.219Z",
  "categories": [
    {
      "id": 2,
      "name": "Brunch",
      "created_by": 1,
      "updated_by": 1,

    }
  ]
}

    final data = jsonEncode({
      'name': name,
      'description': description,
      'categories': category
    });

    var response = await http.post('${api_url}/restaurants', headers: headers, body: data);
  }

  void update(id, params) async {
    final data = jsonEncode({
      'categories': params['categories']
    });

    var response = await http.put("${api_url}/restaurants/${id}", headers: headers, body: data);

# 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.
