Description

This PR removes parameter pressure from the constructors of the following classes:

  • PointerAddedEvent
  • PointerRemovedEvent
  • PointerHoverEvent
  • PointerEnterEvent
  • PointerExitEvent
  • PointerUpEvent See below
  • PointerCancelEvent

It changes converter so that the aforementioned events will not be passed with datum.pressure.

It also changes PointerEnterEvent.fromMouseEvent and PointerExitEvent.fromMouseEvent into redirecting to their unnamed constructors, which drops the arguments down and pressure from the source event.

For reasoning, migration, and discussion, see #30412.

About redo

A first attempt #30414 was found to break devicelab and was reverted. Through investigation, it was found out that events with PointerChange.up can also contain non-zero pressure (see touchEvents which are real recordings).

As a fix, PointerUpEvent has kept its pressure parameter, and will receive datum.pressure when dispatched by event converter. Other changes are unchanged.

I have tested all devicelabs on an android device and it has passed all tests.

An event in bin/cache/pkg/goldens/dev/integration_tests/assets_for_android_views/assets/touchEvents contains PointerChange.up with non-zero pressure. This file is recorded from real events though.

Some event kinds shouldn't allow non-zero pressure
