Overview
Flow Graph is a Flutter package for visualizing Directed Acyclic Graphs (DAGs) in applications. It enables developers to create interactive, customizable node-and-edge diagrams ideal for workflows, data pipelines, or dependency trees. The package supports dynamic updates, drag-and-drop functionality, and responsive layouts, making it suitable for both simple and complex graph representations. Built with Dart, it integrates seamlessly into Flutter projects and leverages the framework's rendering capabilities for smooth performance. Its lightweight design focuses on clarity and usability without requiring external dependencies.
