The Stress Pilot Super App is a high-performance cross-platform application built with Flutter. It acts as the central dashboard for managing test projects, configuring endpoints, and viewing test results.

​
State Management

We use the Provider package for simple and efficient state management across the application. This ensures that our UI remains reactive and updates automatically when the underlying data changes.
provider allows us to inject state objects (ChangeNotifiers) into the widget tree, making it easy to manage both local and global application states. It is a lightweight and flexible alternative to more complex patterns like BLoC.

​
Dependency Injection (DI)

To keep our code decoupled and testable, we use a service locator pattern for Dependency Injection.

GetIt Service Locator

The get_it package acts as our central service locator. It provides global access to singleton instances of our repositories, services, and state objects.
2

Injectable & Build Runner

We use the injectable package to automatically generate the DI configuration. By using annotations like @lazySingleton or @injectable, we ensure that our dependencies are correctly registered during the build process via build_runner.

​
Communication & Networking

The Super App communicates with the stresspilot backend using RESTful APIs over HTTP.

HTTP Client

We utilize the dio package for all HTTP requests. It features interceptors for authentication and logging, which can be found in core/network/http_client.dart.
2

Real-time Updates

For real-time test execution monitoring, the app uses WebSockets (via the stomp_dart_client and web_socket_channel packages) to stream results directly to the dashboard.

​
Key Features Architecture

Our application is built with a feature-based folder structure following Clean Architecture principles.

Modular Features

Each feature (projects, endpoints, results) is self-contained with its own data models, repositories, and presentation logic.

Dynamic UI Generation

The UI for configuring endpoints is built dynamically using the shadcn_ui component library, allowing us to render different input fields based on the selected plugin type.
