Getting Started with Dart
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.yamlfile 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
