Test scroll

main.dart

// Run this sample as a:
// - Web app on Windows
// - Desktop app on Windows
// - Web app on Linux
// - Desktop app on Linux

// For each:
// - scroll with a physical mouse wheel
//   (magic mouse from Apple does not count! It is treated as a trackpad)
// - scroll with trackpad
