CupertinoSegmentedControl does not always respond to selections! #57326
Description
CupertinoSegmentedControl issue
Consider this simple CodePen with a CupertinoSegmentedControl:
As you can see you cannot select option 2 and 5.
Oddly enough if you change the "theFontSize" in the Codepen to 12, you cannot select options 4 or 5.
If you resize the Codepen output so it starts to compress the control's selections a bit, it will start to work correctly!
Steps to Reproduce
- Try it in the CodePen to see it: https://codepen.io/rydmike/pen/GRpXyBQ,
or
- Copy paste the code from the Codepen
- Build for Android with Windows, to an emulator or device
- If the device is wide enough that the segmented control does not get compressed a bit, you will see the same issue on the device as in the Codepen. If the control is a bit compressed horizontally, like it will be on most phone sized devices, it will work correctly. However, if you rotate such a device to landscape mode, it will stop working!
Used version
I tested the above on the live version of Codepen and Dartpad, and also by building to Android emulators PixelC tablet and Pixel3XL phone using API28. I also tested with a real Nexus7 tablet device and an Android OnePlus7 phone.
All tests show the same issue.
I have not tested on iOS devices/simulators by building with a Mac.
