Build number (part after +) is documented as optional, use entire app version if not present (#37036)

You can drag the cupertinoscrollbar if you pass an active scrollcontroller to the scrollbar.

Primarily these methods no longer allocate any objects other than their
return values.

Additionally, the math in the methods is reduced compared to the general
case math based on known input conditions.

Modified to no longer generate infinite values in some finite cases.

This relands https://github.com/flutter/flutter/pull/35297

The followings have been done to fix the broken tests:
  1. Add `didSendFirstFrameRasterizedEvent` extension and its tests
  2. Wait for `didSendFirstFrameRasterizedEvent` instead of
     `didSendFirstFrameEvent` during start up tests
  3. Mark missed (probably newly added) start up tests as flaky
