如何在flutter中设置默认字体颜色

Question

我想全局设置flutter应用程序的默认字体颜色。我试过

ThemeData(
primarySwatch: Colors.blue,
fontFamily: 'Gilroy',
textTheme: TextTheme(
bodyText1: TextStyle(),
bodyText2: TextStyle(),
).apply(
bodyColor: const Color(0xff22215B),
displayColor:  const Color(0xff22215B),
),
),

有些文字是彩色的。但Appbar中的文本不会自动应用。

Answer 1

应用此

ThemeData(
appBarTheme: AppBarTheme(
textTheme: Theme.of(context).textTheme.apply(
bodyColor: const Color(0xff22215B),
displayColor: const Color(0xff22215B),
),
),
textTheme: Theme.of(context).textTheme.apply(
bodyColor: const Color(0xff22215B),
displayColor: const Color(0xff22215B),
),
)

Answer 2

textTheme单独使用不会影响AppBar。您应该使用appBarTheme。试试这个：

appBarTheme: AppBarTheme(
textTheme: TextTheme(
//...
).apply(
bodyColor: Color(0xff22215B), displayColor: Color(0xff22215B))),
