Using feature flags with Flutter

Tggl lets you adopt best practises and add feature flags to your Flutter app in minutes with only a few lines of code.

import 'package:http/http.dart' as http;
 
void main() async {
  var headers = {
    'Content-Type': 'application/json',
    'x-tggl-api-key': 'API_KEY',
  };
 
  var data = '{"userId":"foo","email":"foo@gmail.com"}';
 
  var url = Uri.parse('https://api.tggl.io/flags');
  var res = await http.post(url, headers: headers, body: data);
  if (res.statusCode != 200) throw Exception('http.post error: statusCode= ${res.statusCode}');
  print(res.body);
}

API documentation

Best in class UIEasy to use interface for non-technical users

Empower product and marketing teams to experiment within safe boundaries set by your engineering team.

Your app is instantly updated when a flag is updated, no need to write code and deploy the new version.

PerformanceNo compromise on performance

Tggl is optimized for mobile devices and other client side applications. You can get all the benefits of feature flags with no compromise on performance and interactivity.

A single API call

Tggl requires just one API call at the start of a session to retrieve all flags for a user. Your code then simply checks the initial response.

Tiny payload (<1kb)

Unlike other providers, Tggl's API responses are optimized for mobile devices with slow connexions.

Resilient by design

Tggl ensures your app will never crash due to feature flags. In case of service disruption or network errors, it will simply fall back to a safe state.

Server-side evaluation

Cache the configuration on your backend or use our proxy to locally evaluate flags for each user with no API calls and no overhead on your HTTP responses.

Runs on the edge

Evaluate flags directly on the edge with no API calls and serve customized pages that don’t blink when loaded.

Privacy first

Use the Tggl proxy and make sure your data never leaves your infrastructure. Host it close to your end user for even better performance.

What our clients have to say about us

We chose Tggl as part of our strategy to improve our release process and reliability as we grow. We were using config files and database values as a homemade solution, and the switch to Tggl was surprisingly swift and their technical support very responsive. It has streamlined our release process pretty much instantly and has become our go-to tool for pure technical work like smooth technology migrations and kill switches. It is now an integral part of our workflow.
