[android] [ios] [web] measure returns incorrect values of View if its parent View is scaled using transform style #54988

Open

Description

@psnet

Description

If use measure method to calculate x, y, width, height, pageX, pageY values of View it will return incorrect values in case if parent View has styles:

transform: [
  {
    scale: 2,
  },
],

in this case width, height, pageX, pageY values from measure callback will be doubled compared to real ones.

Specs

  • It is wrong due docs as transform style prop doesnt change layout, transform is used to change appearance only:

    Transforms are style properties that will help you modify the appearance and position of your components using 2D or 3D transformations. However, once you apply transforms, the layouts remain the same around the transformed component

  • It is inconsistent with react-native-web where transform doesnt affect width, height, pageX, pageY values
  • It is inconsistent with response of onLayout callback which will return width, height NOT scaled

Problem

There are 3 different behaviors:

  • react-native-web returns real sizes
  • onLayout returns real sizes
  • measure returns size SCALED due to its parent transform style

Screenshots and Videos

web console logs (3rd and 4th parameters are the same) which is ok:

>>>>> useLayoutEffect measure x, y, width, height, pageX, pageY 134 351 71 39 134 351
onLayoutHandler layout.x, layout.y, layout.width, layout.height 134 351 71 39

Android / iOS console logs (3rd and 4th parameters for measure are 2x bigger than from onLayout):

>>>>> useLayoutEffect measure x, y, width, height, pageX, pageY 176 456 148 78 139 437
onLayoutHandler layout.x, layout.y, layout.width, layout.height 176 456 74 39
