How can I change the color of an string-input in a TextField?

Question

I am working in the styles of my app, i am not able to change the color of the input of the TextField, there isn't any property to change it.

 Theme(             data: new ThemeData(               hintColor: Colors.white             ),             child:         TextField(           focusNode: _focusUsername,           controller: _controller,           decoration: InputDecoration(             border: InputBorder.none,             fillColor: Colors.grey,             filled: true,             hintText: 'Username',           ))), 

Answer 1

You can assign a TextStyle

TextField(   style: TextStyle(color: Colors.white),   ... )

Answer 2

In the example bellow, text is 'red' and the background of the TextField is 'orange'.

TextField(   style: TextStyle(color: Colors.red),   decoration: InputDecoration(fillColor: Colors.orange, filled: true), ) 

Is that what you mean?

If you want to do it generically through the app's theme, it's indeed tricky. It's probably going to be something like that:

theme: ThemeData(     textTheme: TextTheme(       bodyText1: TextStyle(color: Colors.black),       bodyText2: TextStyle(color: Colors.black),       button: TextStyle(color: Colors.black),       caption: TextStyle(color: Colors.black),       subtitle1: TextStyle(color: Colors.red), // <-- that's the one       headline1: TextStyle(color: Colors.black),       headline2: TextStyle(color: Colors.black),       headline3: TextStyle(color: Colors.black),       headline4: TextStyle(color: Colors.black),       headline5: TextStyle(color: Colors.black),       headline6: TextStyle(color: Colors.black),     ),     inputDecorationTheme: InputDecorationTheme(       fillColor: Colors.orange,       filled: true,     ) )
