Getting Started with Dart

✋ Caution

The content of this page might not be fully up-to-date with Strapi 5 yet.

This integration guide follows the Quick Start Guide and assumes you have you have fully completed the "Hands-on" path. You should be able to consume the API by browsing the URL http://localhost:1337/api/restaurants.

If you haven't gone through the Quick Start Guide, the way you request a Strapi API with Dart remains the same except that you do not fetch the same content.

Create a Dart file​

Be sure to have Dart installed on your computer.

take dart-app
touch main.dart

Use an HTTP client​

We'll use http 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,

    },
    "updated_by": {
      "id": 1,
