I have this:
Widget build(BuildContext context) {
return MaterialApp(
title: 'AnApp',
theme: ThemeData(
primarySwatch: Colors.blueGrey,
),
home: MainWidget()
);
}
}
So I have set primarySwatch
color to blueGrey
. How can I access this color inside the MainWidget
class?
I want to set a background the same as the AppBar
color.
我不确定是否有一种方法可以在像这样的小部件内使用primarySwatch
但如果您正在寻找AppBar
颜色,它实际上是primaryColor
并且您可以使用它
Color color = Theme.of(context).primaryColor;
You can use:
color: Theme.of(context).primarySwatch;
OR
you can change the primaryswatch color in main theme class instead of changing in your class by -
Clicking on ctrl + primarySwatch, You will be Headed to theme_data page and there you can change your theme color according to your convience.
Please create the AppTheme class and setup dark and light theme
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
theme: AppTheme.lightTheme,
darkTheme: AppTheme.darkTheme,
themeMode: theme.isDarkMode ? ThemeMode.dark : ThemeMode.light,
home: SplashScreen(),
);
}
