Description

According to flutter drive --help, the option --web-launch-url is

The URL to provide to the browser. Defaults to an HTTP URL with the host name of "--web-hostname", the port of "--web-port", and the path set to "/".

However, in my setting it has no effect.

Steps to Reproduce

  1. Create a new Flutter app.
  2. Replace main.dart with the attached content.
  3. Replace pubspec.yaml with the attached content.
  4. Create test_driver/integration_test.dart with the attached content.
  5. Create integration_test/root_test.dart with the attached content.
  6. Create integration_test/green_test.dart with the attached content.
  7. Start chromedriver on port 4444.
  8. Run:
flutter drive --driver=test_driver/integration_test.dart --target=integration_test/green_test.dart -d chrome --web-port=43000 --web-launch-url='http://localhost:43000/#/green'

Expected results: The browser starts at http://localhost:43000/#/green, the green screen is shown, the test finds a widget with /green text and the test succeeds.

Actual results: The browser starts at http://localhost:43000/#/, the root screen is shown, the test fails to find a widget with /green text.

main.dart 
import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      routes: {
        '/': (context) => Scaffold(
              body: Container(
                child: Center(child: Text('root')),
              ),
            ),
        '/green': (context) => Scaffold(
              body: Container(
                color: Colors.green,
                child: Center(child: Text('/green')),
              ),
            ),
      },
    );
  }
}
