Gesture-Based Navigation
Implementing iOS-like gesture navigation patterns in Flutter for seamless user experience.
Why I Built This
Tech Stack
Technical Approach
Analyzed iOS navigation behavior frame by frame, then recreated the physics and visual cues in Flutter.
Behavior Analysis
Recorded and analyzed iOS navigation gestures to understand the physics curves and thresholds.
Custom PageRoute
Built a custom PageRoute with gesture detection and interactive transitions.
Physics Tuning
Implemented spring physics with carefully tuned damping and stiffness values.
Edge Cases
Handled nested navigators, modal sheets, and conflicting horizontal scrollviews.
Key Learnings
What worked, what didn't, and what I'd do differently.
What Worked
- Spring physics with 0.7 damping ratio feels most natural
- Velocity-based completion threshold improves UX
- Shadow and scale effects add to the premium feel
Challenges Faced
- Gesture arena conflicts with horizontal scrollviews needed careful handling
- Hero animations required special coordination with gesture state
Key Insights
The bigger lessons that go beyond this specific experiment.
Details Matter
The difference between 'good enough' and 'great' is in subtle physics and visual feedback.
Platform Expectations
Users have muscle memory from their platform — respect it or frustrate them.
Test on Real Devices
Gesture performance varies significantly between emulators and real hardware.
