Is there a way that the AppBars color can be changed through a gradient and opacity as an example? From something lighter to something darker to see the icons above the phone clearer.
if I understand correctly you want to change the appbar color with one of these methods :
1) change AppBar color only witch will affect the background of appbar only
appBar: AppBar(
backgroundColor: PrimaryColor,
),
1) change primary App color swatch : witch will change all the colors of buttons , etc to a certain color including appbar
MaterialApp(
primaryColor: Colors.red,
)
2) Switch to dark mode : witch will invert the colors of all app to dark mode
MaterialApp(
title: title,
theme: ThemeData.dark(),
)
