The code in which you change the color of the primaryColor andprimaryColorDark does not change the color inicial of the border  only after tap the color stay black  The attribute that must be changed is hintColor  BorderSide should not be used for this  you need to change Theme   To make the red color default to put the theme in MaterialApp theme       and to change the theme of a specific widget  such as changing the default red color to the yellow color of the widget  surrounds the widget with   new Theme    data  new ThemeData      hintColor  Colors yellow        child          Below is the code and gif   Note that if we define the primaryColor color as black  by tapping the widget it is selected with the color black  But to change the label and text inside the widget  we need to set the theme to InputDecorationTheme  The widget that starts with the yellow color has its own theme and the widget that starts with the red color has the default theme defined with the function buildTheme      import  package flutter material dart    void main     gt  runApp new MyApp      ThemeData buildTheme       final ThemeData base   ThemeData      return base copyWith      hintColor  Colors red      primaryColor  Colors black      inputDecorationTheme  InputDecorationTheme        hintStyle  TextStyle          color  Colors blue                 labelStyle  TextStyle          color  Colors green                          class MyApp extends StatelessWidget      override   Widget build BuildContext context        return new MaterialApp        theme  buildTheme          home  new HomePage                  class HomePage extends StatefulWidget      override    HomePageState createState     gt  new  HomePageState       class  HomePageState extends State lt HomePage gt      String xp    0       override   Widget build BuildContext context        return new Scaffold        appBar  new AppBar          body  new Container          padding  new EdgeInsets only top  16 0           child  new ListView            children   lt Widget gt               new InkWell                onTap                       child  new Theme                  data  new ThemeData                    hintColor  Colors yellow                                    child  new TextField                    decoration  new InputDecoration                        border  new OutlineInputBorder                          hintText   Tell us about yourself                         helperText   Keep it short  this is just a demo                          labelText   Life story                         prefixIcon  const Icon Icons person  color  Colors green                          prefixText                             suffixText   USD                         suffixStyle  const TextStyle color  Colors green                                                                 new InkWell                onTap                                       child  new TextField                  decoration  new InputDecoration                      border  new OutlineInputBorder                        borderSide  new BorderSide color  Colors teal                                             hintText   Tell us about yourself                       helperText   Keep it short  this is just a demo                        labelText   Life story                       prefixIcon  const Icon Icons person  color  Colors green                        prefixText                           suffixText   USD                       suffixStyle  const TextStyle color  Colors green

That is not changing due to the default theme set to the screen   So just change them for the widget you are drawing by wrapping your TextField with new ThemeData    child  new Theme            data  new ThemeData              primaryColor  Colors redAccent              primaryColorDark  Colors red                         child  new TextField              decoration  new InputDecoration                  border  new OutlineInputBorder                      borderSide  new BorderSide color  Colors teal                    hintText   Tell us about yourself                   helperText   Keep it short  this is just a demo                    labelText   Life story                   prefixIcon  const Icon                    Icons person                    color  Colors green                                     prefixText                       suffixText   USD                   suffixStyle  const TextStyle color  Colors green

Inside your lib file Create a folder called colors  Inside the colors folder create a dart file and name it color  Paste this code inside it  const MaterialColor primaryOrange   MaterialColor       orangePrimaryValue       lt int  Color gt           50  Color 0xFFFF9480           100  Color 0xFFFF9480           200  Color 0xFFFF9480           300  Color 0xFFFF9480           400  Color 0xFFFF9480           500  Color 0xFFFF9480           600  Color 0xFFFF9480           700  Color 0xFFFF9480           800  Color 0xFFFF9480           900  Color 0xFFFF9480             const int  orangePrimaryValue   0xFFFF9480   Go to your main dart file and place this code in your theme  theme ThemeData      primarySwatch  primaryOrange      Import the color folder in your main dart like this import  colors colors dart
