Overview
Spine Flutter is the official runtime for integrating Spine animations into Flutter applications. It enables developers to load, display, and interact with skeletal animations created in the Spine 2D animation tool. Designed for game development, it supports smooth playback, real-time animation blending, and event-driven interactions. The package works across multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, ensuring consistent performance and visual fidelity. With minimal setup via `flutter pub add spine_flutter`, it streamlines the integration of high-quality 2D animations into Flutter projects.
