在 Flutter 中更改暗模式的文本颜色（使用动态主题）？

Question

当我进入 select 深色模式时，文本变成白色，但我想将所有文本设为白色 70 或其他内容（包括按钮和常规文本）。如何定义暗模式的默认文本颜色？

我的主题数据现在是这样的：

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return DynamicTheme(
        defaultBrightness: Brightness.light,
        data: (brightness) => ThemeData(
      primarySwatch: Colors.blueGrey,
      brightness: brightness,
        ),

Answer 1

你可以做类似的事情（随意改变你喜欢的东西）：

首先转到 ios/Runner 文件夹。接下来打开 info.plist 并将以下行添加到 Dict 部分。

<key>UIUserInterfaceStyle</key>
<string>Light</string>
<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>

接下来。确保在 MaterialApp 的主题设置中有这些行：

MaterialApp(
    themeMode: ThemeMode.light, // Change it as you want
    theme: ThemeData(
        primaryColor: Colors.white,
        primaryColorBrightness: Brightness.light,
        brightness: Brightness.light,
        primaryColorDark: Colors.black,
        canvasColor: Colors.white,
        // next line is important!
        appBarTheme: AppBarTheme(brightness: Brightness.light)),
    darkTheme: ThemeData(
        primaryColor: Colors.black,
        primaryColorBrightness: Brightness.dark,
        primaryColorLight: Colors.black,
        brightness: Brightness.dark,
        primaryColorDark: Colors.black,      
        indicatorColor: Colors.white,
        canvasColor: Colors.black,
        // next line is important!
        appBarTheme: AppBarTheme(brightness: Brightness.dark)),
