blocks|key|1705657|text|如果您查看一下MaterialButton，您将看到它使用了ButtonThemeData中的getTextColor()方法，并且该方法使用枚举ButtonTextTheme来定义文本颜色。枚举条目是normal、accent和primary。您可以仅根据这些颜色为您的RaisedButton设置全局文本颜色。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1705658|要实现这一点：|1705659|ThemeData+theme+=+Theme.of(context);

If you take a look at <a href="https://github.com/flutter/flutter/blob/1b87f558d5b2d40c79de972a99bbe75e3cc8fb42/packages/flutter/lib/src/material/material_button.dart#L334" rel="nofollow noreferrer"><code>MaterialButton</code></a>, you'll see that it uses the method <a href="https://github.com/flutter/flutter/blob/1b87f558d5b2d40c79de972a99bbe75e3cc8fb42/packages/flutter/lib/src/material/button_theme.dart#L578" rel="nofollow noreferrer"><code>getTextColor()</code></a> from <code>ButtonThemeData</code>, and this method considers the enum <code>ButtonTextTheme</code> to define the text color. The enum entries are <code>normal</code>, <code>accent</code> and <code>primary</code>. You can set a global text color for your <code>RaisedButton</code>s based on those colors, merely.

To implement that:

<pre class="lang-dart prettyprint-override"><code>ThemeData theme = Theme.of(context);

return MaterialApp(
 ...
 theme: theme.copyWith(
 buttonTheme: theme.buttonTheme.copyWith(
 textTheme: ButtonTextTheme.accent,
 ),
 ),
);
</code></pre>

If you want to set a custom color that doesn't match <code>normal</code>, <code>accent</code> or <code>primary</code>, the best option you got is creating a custom <code>Widget</code> with this color, so you don't need to set it in every <code>RaisedButton</code> individually.

Check it out:

<pre class="lang-dart prettyprint-override"><code>class ButtonWithCustomTextColor extends RaisedButton {
 ButtonWithCustomTextColor({
 Key key,
 @required VoidCallback onPressed,
 ValueChanged&lt;bool&gt; onHighlightChanged,
 ButtonTextTheme textTheme,
 // Place your custom color here
 Color textColor = Colors.blue,
 Color disabledTextColor,
 Color color,
 Color disabledColor,
 Color highlightColor,
 Color splashColor,
 Brightness colorBrightness,
 double elevation,
 double highlightElevation,
 double disabledElevation,
 EdgeInsetsGeometry padding,
 ShapeBorder shape,
 Clip clipBehavior = Clip.none,
 MaterialTapTargetSize materialTapTargetSize,
 Duration animationDuration,
 Widget child,
 }) : super(
 key: key,
 onPressed: onPressed,
 onHighlightChanged: onHighlightChanged,
 textTheme: textTheme,
 textColor: textColor,
 disabledTextColor: disabledTextColor,
 color: color,
 disabledColor: disabledColor,
 highlightColor: highlightColor,
 splashColor: splashColor,
 colorBrightness: colorBrightness,
 elevation: elevation,
 highlightElevation: highlightElevation,
 disabledElevation: disabledElevation,
 padding: padding,
 shape: shape,
 clipBehavior: clipBehavior,
 materialTapTargetSize: materialTapTargetSize,
 animationDuration: animationDuration,
 child: child,
 );
}
</code></pre>

blocks|key|1715151|text|对于那些使用轻量主题的应用程序，但是想要在按钮上显示白色文本的人来说，你可以在你的应用程序的入口点(即声明你的MaterialApp的地方)调整buttonTheme。类似于：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1715152|return+MaterialApp(
++theme:+ThemeData.light().copyWith(
++++buttonTheme:+ThemeData.dark().buttonTheme
++),
);|code-block|syntax|javascript|1715153|entityMap^0|1J|B|20|B|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|L|$]]

For anyone with a light-themed app but wants white text on buttons, you can adjust the <code>buttonTheme</code> in your app's entry point (i.e. where you declare your <code>MaterialApp</code>). Something like:
<pre><code>return MaterialApp(
 theme: ThemeData.light().copyWith(
 buttonTheme: ThemeData.dark().buttonTheme
 ),
);
</code></pre>

I would like all my <code>RaisedButton</code> widgets to have a different <code>textColor</code>, how do I change only this in the <code>MaterialApp ThemeData</code>?

Flutter change all raised button text color in theme
