I am trying to change the text color of the “Set time” button in a MaterialTimePicker that opens from a WebView in my Android app. I want to achieve this by modifying the styles.xml file.

time picker

thats my style file

<?xml version="1.0" encoding="utf-8"?>

         Flutter UI initializes, as well as behind your Flutter UI while its
         running.

Problem: The color of the “Set time” button does not change after applying these styles. The time picker opens fine, but the “Set” button still shows the default color.
