Overview
Cue is a physics-first animation library for Flutter that emphasizes natural, realistic motion through a composable and timeline-driven API. Built with performance and developer experience in mind, it allows developers to create complex animations by chaining and combining animation sequences with intuitive control over timing, easing, and physics-based behaviors. Designed for both simple transitions and intricate interactive animations, Cue integrates seamlessly into Flutter apps across all major platforms.
Use cases
- Creating smooth, physics-based UI transitions
- Building interactive gesture-driven animations
- Composing complex animation timelines
- Implementing responsive micro-interactions
- Designing reusable animation components
- Animating layout changes with realism
Key features
- Physics-driven animation engine
- Composable animation building blocks
- Timeline-based sequencing
- Natural easing and momentum simulation
- Cross-platform consistency
- Minimal boilerplate for complex animations
Suitable for
- Flutter developers seeking realistic animations
- Apps requiring interactive or gesture-responsive motion
- Teams prioritizing animation maintainability
- Projects with complex animation workflows
- Developers wanting a declarative animation approach
Considerations
- Requires understanding of physics-based animation principles
- May have a learning curve for beginners
- Best suited for projects where animation quality is critical
- Not ideal for very simple, static transitions
- Performance depends on animation complexity
