This is a simple Flutter app for latency testing and comparison to the Touchpaint Linux kernel module and native Android app. Available modes include:
- Paint with finger (for testing drag latency)
- Fill screen on touch (for testing tap latency)
- Box follows touch (for testing drag latency differently, similar to this Microsoft Research video)
- Blank redraw (for testing baseline rendering performance)
