Configuration is not defined when initializing createClient

[chownation]

Goal

Enable Segment analytics tracking in our app integrated into Flutter module.

Problem

After adding the segment_analytics dependency (per https://github.com/segmentio/analytics_flutter/blob/main/example/lib/main.dart), consistently facing error:

1 error • The function 'Configuration' isn't defined • lib/main.dart:13:7 • undefined_function

Error occurs during the initialization of the analytics client:

   1 analytics = createClient(
   2       Configuration(writeKey: "YOUR_WRITE_KEY"));

Steps Taken

Attempts to resolve:

1. Trying different versions of segment_analytics:

   • ^1.1.9
   • ^1.0.1
   • 1.1.7 (pinned)

2. Trying different import combinations:

   • import 'package:segment_analytics/client.dart';
   • import 'package:segment_analytics/analytics.dart';
   • import 'package:segment_analytics/plugin.dart';
   • A combination of the above.

3. Using fully qualified names:

   • Importing analytics.dart as segment_analytics and using segment_analytics.Configuration.

Current State

Relevant files are in the following state:

pubspec.yaml

specify import 'package:segment_analytics/state.dart' in Installation / Usage

Setting up the client
The package exposes a method called createClient which we can use to create the Segment Analytics client. This central client manages all our tracking events. It is recommended you add this as a property on your main app's state class.

> const writeKey = 'SEGMENT_API_KEY';
> final analytics = createClient(Configuration(writeKey));

You must pass at least the writeKey. Additional configuration options are listed below:
