Getting Started with Flutter

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 Flutter remains the same except that you do not fetch the same content.

Create a Flutter application​

Be sure to have Flutter installed on your computer.

flutter create flutterapp
cd flutterapp

Use an HTTP client​

We'll use http for making HTTP requests.

  • Update the pubspec.yaml file with the following:
...
dependencies:
  flutter:
    sdk: flutter



  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^1.0.0
  http: ^0.12.2
...
  • Install your dependencies by running the following command:
flutter pub get

GET Request to your collection type​

  'Accept': 'application/json'
};

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

print(response.body)
