How to change the text color of the button theme in Flutter

If I add a theme to my app like this:

class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, theme: ThemeData( primaryColor: Color(0xff393e46), primaryColorDark: Color(0xff222831), accentColor: Color(0xff00adb5), backgroundColor: Color(0xffeeeeee), buttonTheme: ButtonThemeData( buttonColor: Color(0xff00adb5), ) ), home: Scaffold( body: MyHomePage(), ), ); }
}

How do I change the text color for the button theme?

If you use ButtonTextTheme.primary Flutter will automatically select the right color for you.

For example, if you make the buttonColor dark like this

 ThemeData( . . . buttonTheme: ButtonThemeData( buttonColor: Colors.deepPurple, // <-- dark color textTheme: ButtonTextTheme.primary, // <-- this auto selects the right color ) ),

The text is automatically light. And if you make the buttonColor light, then the text is dark.

 ThemeData( . . . buttonTheme: ButtonThemeData( buttonColor: Colors.yellow, // <-- light color textTheme: ButtonTextTheme.primary, // <-- dark text for light background ) ),

Suragch's answer is correct, but sometimes we want to set a completely custom color as button text color. It is achievable by providing a custom colorScheme with secondary color set:

buttonTheme: ButtonThemeData( buttonColor: Color(0xffff914d), // Background color (orange in my case). textTheme: ButtonTextTheme.accent, colorScheme: Theme.of(context).colorScheme.copyWith(secondary: Colors.white), // Text color
),

I believe the more updated answer is mainly found here:

elevatedButtonTheme: ElevatedButtonThemeData( style: ButtonStyle( backgroundColor: MaterialStateProperty.all<Color>(Colors.black,), //button color foregroundColor: MaterialStateProperty.all<Color>(Color(0xffffffff),), //text (and icon) ),
),

Depending on the button change...

elevatedButtonTheme: ElevatedButtonThemeData()
outlinedButtonTheme: OutlinedButtonThemeData()
textButtonTheme: textButtonThemeData()

theme: ThemeData( textButtonTheme: TextButtonThemeData( style: TextButton.styleFrom( primary: Colors.blueGrey[900], ), ), ),

Update (New buttons):

Enabled state:

Disabled state:

ButtonTheme won't work for new buttons like ElevatedButton. For that you should set elevatedButtonTheme.

• Less customizations:

  MaterialApp( theme: ThemeData( elevatedButtonTheme: ElevatedButtonThemeData( style: ElevatedButton.styleFrom( primary: Colors.red, // Button color onPrimary: Colors.white, // Text color ), ), ),
  )

• More customizations:

  MaterialApp( theme: ThemeData( brightness: Brightness.dark, elevatedButtonTheme: ElevatedButtonThemeData( style: ButtonStyle( backgroundColor: MaterialStateProperty.resolveWith<Color?>((s) { if (s.contains(MaterialState.disabled)) return Colors.brown; // Disabled button color return Colors.red; // Enabled button color }), foregroundColor: MaterialStateProperty.resolveWith<Color?>((s) { if (s.contains(MaterialState.disabled)) return Colors.white30; // Disabled text color return Colors.white; // Enabled text color }), ), ), ),
  )

Similarly, you can do this for OutlinedButton and TextButton by replacing ElevatedButton and its properties.

I advice you to set it in the app theme, so it will be applied everywhere:

src/theme/style.dart

final appTheme = () => ThemeData( accentColor: Colors.white, buttonTheme: ButtonThemeData( buttonColor: Colors.orange, textTheme: ButtonTextTheme.accent, ), );

Then use it in your src/app.dart as theme: appTheme(),

Try it :

RaisedButton( onPressed: () => print('pressed'), child: Text('Press me'),
)

Andrey Gordeev's answer works. However I was curious what's going on so do a check on it as lacking a bit of explanation. Basically you need to set the textTheme to accent in order to use the colorScheme to set the button color. You can also override the button color using the primary in the colorScheme.

From the source code

The colors for new button classes can be defined exclusively in termsof [colorScheme].
When it's possible, the existing buttons will (continue to) gradually migrate to it.

buttonTheme: ButtonThemeData( textTheme: ButtonTextTheme.accent, colorScheme: Theme.of(context).colorScheme.copyWith( primary: Colors.orange, // secondary will be the textColor, when the textTheme is set to accent secondary: Colors.white, ),
),
