Getting Started with Flutter

🏗 Work in progress

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 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

headers: headers
);

print(response.body)
