问题描述

我设法更改了 hintStyle -color

I managed to change the hintStyle-color

@override
ThemeData appBarTheme(BuildContext context) {
  return ThemeData(
    primaryColor: kPrimaryColor,
    primaryIconTheme: IconThemeData(
      color: Colors.white,
    ),
    inputDecorationTheme: InputDecorationTheme(
      hintStyle:
        Theme.of(context).textTheme.title.copyWith(color: Colors.white),
    ),
  );
}

但是，如果我在应用栏搜索栏中输入了一些内容，则颜色仍然是黑色...

But if i type something into the appbar searchfield, the color is still black...
