Summary:
This PR fixes the unexpectedly growing height of the single-line TextInput example by ensuring multiline={false}, numberOfLines={1}, and removing vertical padding.
Previously, the single-line text input in the provided example would grow in height as the user typed more characters. Attempts to fix this through native code changes were not effective. The root cause was JS-side styling and props that induced multiline or added extra vertical space.
Updated the ExampleTextInput usage to explicitly set multiline={false}, numberOfLines={1}, and paddingVertical: 0. This ensures the input remains a stable, single line with no vertical growth.
Changelog:
[General] [Fixed] - Single-line TextInput example no longer grows in height unexpectedly.
Test Plan:
Manually tested the modified example to confirm that the TextInput no longer grows vertically when typing on an Android emulator.
