How to change default back button icon in Flutter?

Question

How I will change the back button icon in flutter using the theme. So it can be reflected throughout the application. I saw multiple options in the theme to change the size and color of the icon. But didn't see the change icon option.

Answer 1

You can override the back button icon using the global theme

ThemeData(
  actionIconTheme: ActionIconThemeData(
    backButtonIconBuilder: (BuildContext context) => SvgPicture.asset('assets/arrow-back-ios.svg'),
  ),
);
