Eppo is a composable next-generation feature flagging and experimentation platform focused on tightly integrating with your existing tech stack.
Eppo SDK for Dart and Flutter #
The Eppo SDK enables feature flags and experiments in your Dart and Flutter applications with only a few lines of code.
The SDK handles all the complexity of feature flag evaluation and experiment assignment locally in your application. The guide below will walk you through installing the SDK and implementing your first feature flag, experiment, and contextual bandit.
See https://docs.geteppo.com/sdks/client-sdks/dart/quickstart/ for detailed usage instructions.
import 'package:eppo/eppo.dart';
// Initialize the SDK
await Eppo.initialize(
'your-sdk-key',
SubjectEvaluation(
subject: Subject(
subjectKey: 'user-identifier'
)
)
);
// Make an assignment
final String variation = Eppo.getStringAssignment(
'my-neat-feature',
'default-value',
);
// Render different components based on assignment
switch(variation) {
case 'landing-page-a':
return renderLandingPageA();
case 'landing-page-b':
return renderLandingPageB();
default:
return renderLandingPageC();
}
