The engineers at Apple added a toggle for users to switch between light and dark appearance. This theme helped people use apps in environments with lower light.ДЇortunately, in iOS13, Apple decided to grant this feature system-level love.

With the dialog created we can add it to the onPressed methods in the FlatButton widgets for the colour selection. _customTheme = (primarењњolor) ? _pyWith(primarењњolor: color) : _pyWith(accentColor: color)), Note we use the primarењњolor boolean variable to tell the picker widget whether to save the selected colour as the primary or accent colour in the _customeTheme variable. This subsequently updates the custom theme rounded button to whatever was chosen.
